Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to take part more actively in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* On December 31, 2021, Tianchen Company successfully carried out the initial feeding process for China’s first fluidized bed methanol-to-propylene (FMTP) plant, built by Gansu Huating Coal Industry Group! ! ! This project is a technology demonstration facility for producing 200,000 tons of polypropylene from 600,000 tons of methanol using a fluidized bed process, and it is based on the core technologies of the Reaction Engineering Laboratory (FLOTU) at the Department of Chemical Engineering at Tsinghua University. It represents China’s first fluidized-bed methanol-to-propylene plant, having gone through 23 years of research and development as well as engineering work. Based on over 20 years of research, the research group led by Professor Wei Fei from the Department of Chemical Engineering at Tsinghua University has developed a fluidized-bed methanol-to-propylene technology, using interfacial SAPO molecular sieves as catalysts and building upon the efficient conversion techniques for ethylene, butylene, and higher-carbon alkenes into propylene. First, the methanol to olefins reaction is carried out in a fluidized bed reactor, while in another reactor the conversion of the separated ethylene and butylene into propylene takes place, ultimately yielding propylene as the product.

First, the methanol to olefins reaction is carried out in a fluidized bed reactor, while in another reactor the conversion of the separated ethylene and butylene into propylene takes place, ultimately yielding propylene as the product.
In 2009, an industrial-scale trial with a capacity of 30,000 tons per year was successfully completed, marking the success in the development of the core industrial technology for FMTP with independent intellectual property rights; the carbon-based yield from propylene reached over 72%. In 2012, the construction of a 600,000-ton/year fluidized-bed methanol to propylene (FMTP) technology demonstration project was initiated by Huaning Huating Coal Industry in China, with China Tianchen Engineering Co., Ltd. serving as the general contractor. Since the official commencement of the project, all members of Tiantian Company’s Huating FMTP Technology Demonstration Project Team have worked tirelessly, successfully completing various milestone tasks such as the installation of large-scale equipment, the installation and pressure testing of process pipelines, electrical and instrumentation debugging, the startup of the unit, fluidization tests of the three related devices, and the mechanical completion of the project. These efforts ensured that the project’s commissioning was successful on the first attempt. A successful feeding of this project has laid a solid foundation for the consistent production of high-quality polypropylene products. It holds great significance for extending the coal chemical industry chain and promoting the sustainable, healthy, green, and circular development of the modern coal chemical industry.
