A new option for coal-to-ethanol production—the Jupeng biological method

Thread Content

01 The ethanol market has broad prospects. Influenced by factors such as the \"oil crisis\" in the mid-1970s, the fuel ethanol industry developed rapidly in many countries, especially in Brazil, Europe, and the United States. The use of ethanol-blended gasoline can, on the one hand, reduce dependence on crude oil, and on the other hand, increase the octane rating of gasoline while reducing the emission of pollutants in exhaust gases. In 2016, China’s production of fuel ethanol was 2.6 million tons, indicating significant room for growth when compared to the consumption levels in the United States, which were 45.8 million tons, and in Brazil, which was 21.8 million tons. Our country consumes nearly 120 million tons of gasoline per year; based on a 10% addition rate of ethanol, there is a demand gap of almost 10 million tons for ethanol compared to the current level. http://www.mhg114.com/data/attachment/forum/201710/10/15281566vkkoh8ztqo8m9n.png Uploaded 5 hours ago.

The biological fermentation method primarily uses materials such as corn, wheat, and tubers as raw materials, and produces anhydrous ethanol through processes such as fermentation, distillation, and dehydration ； Coal-to-ethanol is one of the emerging development directions in China’s coal chemical industry, encompassing processes such as the catalytic synthesis of ethanol from syngas, direct hydrogenation of acetic acid, hydrogenation of acetate esters, and the production of ethanol through microbial fermentation using industrial waste gas/syngas. http://www.mhg114.com/data/attachment/forum/201710/10/152816ddoapa52p3cma6ap.png Uploaded 5 hours ago.

In the aforementioned process route, the catalysts used in the precious metal catalysis method are precious metals such as rhodium, which result in high costs ； In the acetic acid route, there is severe corrosion caused by acetic acid, high catalyst costs, large amounts of waste acid, and environmental pollution ； The dimethyl ether route involves carbonylation, followed by catalytic hydrogenation, to obtain a mixture of low-carbon alcohols; after purification and separation, anhydrous ethanol can be obtained. This method has the advantages of lower corrosivity and reduced energy consumption for separation compared to the direct hydrogenation of acetic acid, but it also has the disadvantages of more reaction steps and more complex equipment. http://www.mhg114.com/data/attachment/forum/201710/10/152817mhtrmzezy0m6yfyt.png Uploaded 5 hours ago.

Jupeng Bio was formerly known as Ineos Bio, and it was established by Ineos Group, one of the world’s leading chemical companies. In 1989, the core fermentation technology was discovered; in 2003, integrated pilot tests were conducted; and in 2008, Ineos Bio was established. In February 2011, Ineos Bio began constructing a pilot plant in Vero Beach, Florida, capable of processing 300 tons of biomass per day and producing 24,000 tons of ethanol annually; it was the world’s first facility to produce ethanol through biomass gasification followed by continuous microbial fermentation. In July 2013, Ineos Bio announced that the plant had begun commercial-scale production of bioethanol. http://www.mhg114.com/data/attachment/forum/201710/10/1528171odo1f1rrpofdbuo.png Uploaded 5 hours ago.

As the ethanol market in the United States has changed and the economic drivers behind Ineos’ technological development are no longer aligned with its strategic goals, Ineos launched a global tender in August 2016 to sell this technology. In November 2016, Jupeng Bio began negotiations with Ineos. Driven by its commitment to bioethanol technology and its vision for its application, it stood out among numerous international competitors. In April 2017, it successfully passed the CFIUS review in the United States and completed the acquisition. At the core of the Jupeng biotechnology platform are unique microbial bacteria with high selectivity and high efficiency for converting syngas into ethanol. This bacterium is a strain discovered in nature and selectively cultivated over many years, and it performs better than any other known traditional catalyst. Syngas, a mixture of CO and H2, is cooled and purified before being fed into the fermentation reactor. Our company’s unique microbial bacteria, suspended in water, convert syngas into ethanol efficiently, rapidly, and with high selectivity. After the reaction, a solution containing ethanol is formed; through distillation for purification and drying, anhydrous ethanol can be obtained, which can then be used as a clean fuel or as a chemical intermediate. Advantages of the Jupeng biological method ◆ Simple process, operates at normal temperature and pressure. ◆Syngas does not require conversion and can be processed directly. ◆It can be connected to PSA exhaust gas, etc. ◆Bacteria reproduce automatically and do not need to be replaced. ◆Bacteria have a high tolerance for the vast majority of impurities. ◆It exhibits high selectivity and high conversion rate for ethanol. ◆In continuous fermentation, the conversion can be completed within a few minutes.
