The difference between MTP and MTO

There are three differences: 1. The main products are different (different product distribution) 2. The catalysts are different 3. The catalytic processes are different

Brief reply: 1. Both MTO and MTP technologies belong to the category of using methanol to produce olefins. The main difference is that MTO technology uses methanol to produce ethylene, propylene and butadiene products ； MTP technology uses methanol to produce a single propylene product. 2. There is no mature industrialized technology for MTO and MTP in China. The MTO technology patent holder is mainly UOP/Hydro Company, and the MTP patent holder is mainly Germany's LURGI Company. The Dalian Institute of Chemical Physics, Chinese Academy of Sciences, is also conducting relevant research in China and has made certain progress. 3. The MTO process is a technology successfully developed in 1995 by UOP Company of the United States and HYDRO Company of Norway. This process uses methanol as raw material and produces olefin products mainly ethylene and propylene through methanol cracking. Depending on the raw material of methanol, there are two routes: natural gas and coal. 4. Currently, the main company engaged in MTP technology development in the world is Lucci. In January 2002, Lurgi Company built an MTP pilot plant in Norway, which ran continuously for 8,000 hours by September 2003. The pilot plant used the MTP catalyst from the German Sud-Chemie AG. The catalyst has the characteristics of low coking and extremely low propane production, and has achieved industrial production. At present, MTP technology has completed the process design of industrial equipment. Lurgi MTP reactors are available in two forms: That is, fixed bed reactors (only produce propylene) and fluidized bed reactors (can co-produce ethylene/propylene). At present, Lucci Company has signed technology transfer agreements with Shenhua Ningxia Coal Group and Datang respectively. Datang International Coal Chemical Industry's polypropylene project with an annual output of 460,000 tons is stepping up construction and is expected to be put into operation in 2009. (Inner Mongolia Datang International Xilingol League Coal Chemical Project plans to use lignite from the Shengli Coalfield in Xilinhot City, Inner Mongolia as raw material, and adopt a series of production technologies such as Shell pulverized coal gasification, gas shift, Lurgi low-temperature methanol washing, Lurgi low-pressure methanol synthesis, Lurgi MTP propylene production technology, Spheripol polypropylene production technology, etc., with an annual output of 1.68 million tons of intermediate product methanol, 460,000 tons of final product polypropylene and other by-products. ) This post was last edited by zjyang168168 on 2008-1-7 11:46 ]

reply: 1. Since the early 1980s, Dalian Institute of Chemical Physics has taken the lead in conducting research on producing low-carbon olefins from natural gas or coal. In 2004, the institute cooperated with Shaanxi Xinxing Coal Chemical Technology Development Co., Ltd. and Sinopec Luoyang Petrochemical Engineering Company to jointly carry out a 10,000-ton industrial test of methanol to olefins (DMTO) (Shaanxi's 16,000 tons/year industrial test device has been successfully put into operation), forming a world-leading set of innovative technological achievements with my country's independent intellectual property rights. 2. On August 15, 2007, Shaanxi Xinxing Coal and Olefins Co., Ltd.’s 3 million tons coal-based methanol to olefins project obtained my country’s first methanol to low carbon olefins (DMTO) technology transfer with independent intellectual property rights. That is, the "Shaanxi Yulin 200,000 tons/year coal-based olefin industrialization demonstration project" DMTO technology license transfer. This technology was jointly developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Luoyang Petrochemical Engineering Company, and Shaanxi Xinxing Coal Chemical Technology Development Co., Ltd. Currently, this project is listed as * * Coal-to-olefins demonstration project, * * and Shaanxi Province’s “Eleventh Five-Year Plan” key construction projects. 3. On September 17, 2007, Dalian Institute of Chemical Physics and Shenhua Group held a signing ceremony for a 600,000 tons (olefins)/year methanol-to-olefins (DMTO) technology transfer contract in Beijing.

original meaning in english: MTO - Methanol to Olefins MTP - Methanol to Propylene Methanol to propylene So MTP is more narrow, and methanol to propylene MTO is broader, but mainly methanol refers to olefins mainly ethylene and propylene. MTO and MTP are not necessarily and directly related to coal. Their precursor raw materials can be coal, natural gas, inferior oils, light hydrocarbons, etc., and even the popular biomass

Shaanxi Xinxing Coal and Olefin Co., Ltd. is honored to be our company

MTO: refers to a process technology that uses methanol synthesized based on coal or natural gas as raw material, with the help of a fluidized bed reaction similar to a catalytic cracking unit, to mainly produce ethylene; MTP: refers to a process technology that uses methanol synthesized from coal or natural gas as raw material, with the help of a fluidized bed reaction similar to a catalytic cracking unit, to mainly produce propylene.

Who said the MTO test of Shanghai Institute of Technology in Yanhua was successful? Please give details.

Sinopec Shanghai Petrochemical Research Institute recently succeeded in the pilot test of MTO in Yanhua. It is said that its performance is better than that of Dahua? All details

I hope relevant indicators can be given, it would be inappropriate to talk nonsense like this. According to what I know (both Dahua Institute of Chemical Industry and Sinopec have a good understanding of it), as far as the current MTO technology in China is concerned, Dahua Institute of Technology is far ahead in terms of catalyst originality, catalyst performance, research methods and industrial performance. Sinopec's MTO catalysts may have intellectual property issues, and the catalysts of the Shanghai Petrochemical Institute are related to Sinopec's internal units such as the Beijing Petrochemical Institute, BEPK, and East China University of Science and Technology. If there are many more things in the husband's family, it will be more complicated. The MTO technology of Dahua Institute only has one in-law, so things may be simpler.

Can you list the indicators? It is said that it will be evaluated in the near future. The BEPK mentioned above should be SEI. This post was last edited by zhdgzhdg on 2008-1-23 19:43 ]

DMTO of the Dalian Institute of Chemical Physics was developed based on the DMTO technology of the U.S. company UOP? Who made the conclusion? Is it UOP?

The products of MTO are ethylene, propylene and a small amount of n-butene. The products of MTP are propylene, naphtha, LPG and a very small amount of ethylene. The cracking reactor of MTO is a fluidized bed, and the catalyst is SAPO-34. The cracking reactor of MTP is a fixed bed, and the catalyst is ZSM-5. Both produce large amounts of water. None of them have industrial experience. Some of them have experience in pilot or industrial trials, and the continuous operation time is not long. They are still some distance away from industrialization. Before the demonstration plant is put into operation and stabilized, large-scale construction is risky.

You may have a misunderstanding, thinking that MTP products are single propylene, and MTP technology is simpler than MTO technology. In fact, it is not the case. The catalytic reaction of MTP is carried out in two steps. The first step is MTO. The second step is the process of passing the ethylene, butene, pentene, etc. generated by the MTO reaction through the second reactor (EBTP reaction) and converting it into propylene through catalyst selection. Therefore, MTP technology is more complex and difficult than MTO technology. The MTP device can also produce all MTO products, but the MTO device cannot achieve the high propylene selectivity of the MTP device. This is the essential difference between MTP technology and MTO technology. Currently, Dalian Institute of Chemical Physics and Sinopec have completed the MTO pilot plant. The MTP pilot plant was jointly developed by Tsinghua University and China National Chemical Engineering Group Corporation. It is expected to be put into production by the end of this year. This technology has obtained * * Invention patent. Lucci's MTP in Datang is a fixed-bed reactor, while the pilot plants of Tsinghua University and China National Chemical Engineering Group are fluidized-bed reactors. There are essential differences between the two. I hope that experts engaged in the research, development and application of coal chemical technology will cheer for the research on the world's first fluidized bed MTP technology developed by our people.

1. MTP product distribution is wider than MTO (refer to the 21st floor). This is correct, so the separation process will be more complicated.； 2. The product of the first step of MTP reaction is DME, and the second step converts DME into hydrocarbons. This is clearly evident in the design of Lurgi’s three fixed beds. There is no such absurd statement as "the first step is MTO". Although MTO and MTP are both methanol to olefins, the catalysts, process routes, and product distribution are essentially different. They are two routes and two technologies. 3. Tsinghua University’s MTP fluidized bed is about to be put into pilot testing in Anhui. I wish Professor Wei Fei good luck.

Agree with Brother Fei! After the success of the Dahua Institute, a press conference was held in the Great Hall of the People in August 2006. If Sinopec had been equally successful in Yanshan last October (not to mention more successful than the Dahua Institute), they would have held a press conference on the moon, but they remained silent, low-key, low-key. . . It's so respectable :'(

Duolun's polypropylene is from Unipol technology.

Domestic technology is so mature, why does Yankuang Yulin Nenghua still use Lucci's technology? I really don’t understand

MTO: Methanol to olefins, olefins include ethylene and propylene, where the production ratio of ethylene and propylene can be adjusted within a certain range ； MTP: Propylene is produced from methanol, and the product is propylene.

MTG is methanol to alkanes, MTO is methanol to olefins, and MTP is specifically methanol to propylene. This post was last edited by andyzheng on 2008-11-18 10:50 ]

MTP reacts in two steps, but the first step is to generate dimethyl ether, which cannot generate all the components of MTO. The product is determined by the catalyst, especially the pore size of the catalyst.
