The world’s first pilot project for producing ethanol from syngas yielded qualified product. Author/Source: Date: 13-01-2017. Clicks: 76. At 9 a.m. on January 11, the highly anticipated 100,000-ton-per-year industrial pilot project for producing ethanol from syngas carried out by Yanchang Petroleum was successful in its first batch of production, resulting in anhydrous ethanol with a purity of 99.71%. This marks the success of the world’s first industrial pilot project for producing ethanol from syngas, representing another significant breakthrough in the application of advanced coal chemical technology in China. It is reported that the syngas-to-ethanol industrial demonstration project is an industrial demonstration project jointly developed by Yanchang Petroleum and Dalian Institute of Physical Chemistry. It has been designated as a key project under Shaanxi Province’s Science and Technology Innovation Plan, as well as a major task within the Chinese Academy of Sciences’ strategic pilot project on \"Key Technologies and Demonstrations for the Clean and Efficient Utilization of Low-Rank Coal.\" The total investment in this project was 743 million yuan. Construction began in October 2015, and with the strong support of the group company and the close cooperation of units such as the Dalian Institute of Physical Chemistry, Huajian Company, Beijing Engineering Company, and Xinghua Company, the project was completed efficiently and to a high standard within just one year, including the construction, equipment installation, and commissioning phases. At present, the pilot production of this project is operating stably, the product quality is satisfactory, and all process parameters are within normal ranges; efforts are being made to achieve full production capacity and meet the required standards as soon as possible.
This sounds really amazing. If that were really the case, it would be terrible. However, the extended R&D was just a formality; nothing else followed. Go to another place and put one there. But when I look at the Dalian Institute of Chemical Physics, it seems a bit more reliable.
I couldn’t help it and searched again for something called the GP syngas method. Pure PZ. In recent years, there has been an overcapacity of acetic acid production in the domestic market, with costs remaining consistently negative. The adoption of methanol fuel is hindered by issues such as the lack of relevant standards, its toxicity, and its corrosive effect on non-metallic components in fuel systems. This has prompted many research institutions and investors to pay attention to coal-based ethanol. Given the current technological conditions, developing coal-based ethanol can not only consume large amounts of acetic acid, thereby alleviating the issue of overcapacity in acetic acid production, but it can also replace some petroleum with ethanol-based gasoline, reducing the country’s dependence on imported petroleum and lowering vehicle exhaust emissions – thus bringing about positive environmental and social benefits. Some experts have even predicted that coal-to-ethanol could become another investment hotspot and the most promising development direction in coal chemical industry, following coal-to-olefins, coal-to-natural gas, coal-to-oil, coal-to-ethylene glycol, and coal-to-aromatics. So, can coal-based ethanol truly become the sixth pathway for modern coal chemical industry? The journalist’s investigation helps you find **. Technological breakthroughs led to a sharp increase in such projects. On April 28, 2016, the 30,000-ton/year industrial demonstration plant for the production of ethanol via acetic acid hydrogenation, built using technology from the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences, was successfully commissioned with its first batch of feed and has since operated steadily. According to Ding Yunjie, a researcher at Dahuahua Research Institute, the operation results of Sopco’s 30,000 tons per year demonstration plant show that, under basically identical conditions regarding material and energy consumption, the acetic acid hydrogenation technology developed by Dahuahua Research Institute is capable of producing anhydrous ethanol with a purity of over 99.6%. This indicator is nearly 5 percentage points higher than the acetic acid hydrogenation technology used by Solutia in the United States, indicating that the technology developed by Dahuaxue Institute is at the international leading level. This is another advanced coal-to-ethanol technology that Da Hua has announced after a month. In early March this year, Liu Zhongmin, deputy director of the Dahuahua Research Institute and an academician of the Chinese Academy of Engineering, revealed that the 100,000-ton-per-year industrial ethanol production facility using coal as a feedstock, developed by the Dahuahua Research Institute – which employs technologies such as converting coal into syngas followed by methanol production, then dimethyl ether production, carbonylation of dimethyl ether to produce methyl acetate, and hydrogenation of methyl acetate to obtain anhydrous ethanol – is set to be completed and put into operation in October. Process packages for capacities of 200,000 tons per year and 300,000 tons per year using this technology are currently under development. Ding Yunjie revealed that, driven by the promising prospects for coal-based ethanol production, the institute has simultaneously carried out research on four different technologies for producing ethanol from coal: ethanol synthesis via the hydrogenation of syngas with carbon dioxide derivatives, ethanol synthesis via the hydrogenation of syngas with acetic acid, ethanol synthesis via the hydrogenation of olefins/acetic acid through esterification, and ethanol production via the carbonylation and hydrogenation of methanol/syngas. Significant technical breakthroughs have been achieved in all of these areas. Among them, the industrial pilot scale of producing ethanol from syngas via the hydrogenation of dicarbonyl compounds is set to be completed this year at a scale of thousands of tons ； The two technologies of producing ethanol from syngas via acetic acid hydrogenation, and producing ethanol from olefins/acetic acid via ester hydrogenation, have been put into industrial use ； An industrial demonstration plant for the production of ethanol via methanol/syngas carbonylation hydrogenation is under construction. If this is considered as the production of ethanol from syngas, then the hydrogenation of acetic acid also starts from syngas. http://qoofan.com/read/YlP9vo13GQ.html
The route is a bit long; I’m not sure about the cost-effectiveness
What to do after it’s made? Was it sold directly? What is it used for? :)
Acetic acid is hydrogenated to produce ethanol; ethanol then reacts with acetic acid to form ethyl ester, which is subsequently hydrogenated to yield ethanol again. . . . . . . . Going on and on, just playing around.
\"Environmental Protection of Diesel Vehicles: Taking Advantage of Ethanol-Related Products\" comes from WeChat ID 18204201692. In the past, ethanol was used primarily for blending into gasoline to create \"ethanol gasoline\". Among the ethanol-based products designed for use in diesel engines, only the \"Diesel Engine Liquid Booster\" invented by the author has a work equivalent comparable to that of diesel fuel of the same volume. The mixing ratio of this booster with diesel in the combustion chamber ranges from 1:5 to 1:2.5; it helps reduce fuel consumption by 17%-25%, results in lower carbon emissions and is environmentally friendly, while also enhancing power output by 17%-25%. \"Diesel engine liquid booster\" is made using aqueous ethanol as the main raw material – estimation: For diesel trucks with a power of over 300 horsepower, each 10,000 units consume 100,000 tons of ethanol per year... For every million units, the annual ethanol consumption is 10 million tons, and so on. This \"Diesel Engine Liquid Booster\" is used in diesel engine intakes; therefore, ethanol-related products are sold separately and independently, with no connection to or constraints imposed by the petroleum industry. “Diesel Engine Liquid Booster” Patent No. ZL201210031768.6
Fuel ethanol is recognized as an environmentally friendly fuel for use in vehicles. The volume of this fuel produced indicates the extent to which emissions from gasoline-powered vehicles can be controlled in terms of environmental impact. When 10% fuel ethanol is mixed with regular gasoline, its energy output is lower than that of pure gasoline. However, to avoid fuel blending: ethanol-based products such as \"diesel engine liquid boosters\" are used in diesel engine intakes; their energy output is equivalent to that of diesel of the same volume. The mixing ratio of this substance with diesel in the cylinder ranges from 1:5 to 1:2.5, allowing it to replace 17%–25% of the diesel used, while simultaneously increasing power output by 17%–25% – a figure far higher than the proportion of ethanol used to replace gasoline. Based on an annual consumption of 100 million tons of gasoline by gasoline-powered vehicles, 10 million tons of fuel ethanol need to be blended in ； If ethanol is used in diesel engine intakes, and assuming an annual diesel consumption of 100 million tons, then 17 million tons to 25 million tons of ethanol would be required per year. This amount can replace 17 million tons to 25 million tons of diesel, and when combined, the total demand for ethanol could reach 27 million tons to 35 million tons. From the perspective of alternative energy, the huge market gap resulting from insufficient biomass ethanol production can only be filled by expanding the capacity of the emerging coal-based ethanol industry
The functional role of fuel ethanol is to serve as an environmentally friendly fuel for vehicles: (1) partially replacing petroleum, and (2) reducing exhaust pollution emissions. However, the way fuel ethanol is blended into gasoline differs significantly from that of diesel engine liquid boosters in terms of how they enter the market: (1) Fuel ethanol intended for use in gasoline-powered vehicles can only be blended into gasoline by companies in the petroleum refining industry; designated ethanol production enterprises do not have the authority to carry out this process. (2) The ethanol-based product designed for use in diesel engines, namely the “Diesel Engine Liquid Booster,” does not need to be mixed with diesel at all. Using ethanol as its main ingredient, this liquid booster vaporizes in the intake system of the diesel engine, thereby allowing it to replace a large amount of diesel fuel. Therefore, ethanol production enterprises that are not **designated have full operational autonomy; they do not need to go through the petroleum industry and are not subject to the constraints and limitations imposed by petroleum blending. As a result, they are freed from the exclusive monopoly of the petroleum industry. (3) The end of the fuel ethanol industry chain is the market for environmentally friendly energy for vehicles. However, one should not focus solely on \"ethanol gasoline\" in a one-sided manner, without also paying attention to the huge market for using ethanol in diesel engines. The demand for diesel engines to utilize ethanol as an environmentally friendly energy source is, relatively speaking, much greater than that for ethanol-blended gasoline. Only through a comprehensive strategic approach by ethanol production companies can strong momentum be created to drive the rapid development of the industry related to ethanol as an environmental fuel. Therefore, coal-to-ethanol has a very bright future.
If it can be sold at the price of alcohol, the profits would be quite high: lol. But as a gasoline additive, with current oil prices, and given such long processing times and energy consumption, do you think it would be profitable? It only increases the total carbon emissions
\"Diesel Engine Liquid Booster\" is a product derived from ethanol: used as an additive for diesel engine compression, it is atomized in the intake manifold and mixed with air before being drawn into the combustion chamber. It can replace part of the diesel fuel, increase the engine’s power, and effectively control exhaust pollution emissions. Its demand far exceeds that of ethanol-based gasoline; it offers significant economic benefits and irreplaceable social advantages. It represents a breakthrough point for the coal-to-ethanol industry to expand its production capacity and gain access to large consumer markets
