The Fluidized Bed Methanol to Olefins (FMTP) technology was developed jointly by China National Chemical Engineering Group, Tsinghua University, and Huaihua Group. The three parties built a pilot-scale fluidized-bed methanol to propylene (FMTP) plant in Huainan, Anhui, with a methanol processing capacity of 30,000 tons per year. The plant was completed by the end of 2008; by August 2009, it had produced 11 tons of catalyst and undergone secondary fluidization tests, thereby fully establishing the system’s process flow. This technology uses a SAPO-34 catalyst and a fluidized-bed reactor, just like the MTO process. However, after separating the propylene from the products, the C2 components and those with a carbon number of 4 or higher are fed into a separate olefin conversion reactor where they are converted into propylene. It is claimed that by using this technology to produce olefin products with propylene as the target product, the overall yield of propylene can reach 77%, with a methanol consumption of 3 tons per ton of propylene. Using this technology to produce olefin products based on propylene, the overall yield of dienes (ethylene + propylene) can reach 88%, with a methanol consumption of 2.62 tons per ton of dienes. Data from Yahuazheng Consulting shows that Tsinghua University holds 30% of the rights related to the FMTP technology ； Sinopec Engineering Group accounts for 24% ； China Tianchen Chemical Engineering Company accounts for 18% ； Donghua Technology accounts for 18% (both Tianchen and Donghua Technology are subsidiaries of China National Chemical Engineering Corporation) ； Anhui Huaihua Group holds 10%. Commercial demonstration projects for FMTP technology are underway. Building on its existing 600,000 tons per year methanol production facility, Huating Zhongxu Coal Chemical Company plans to construct a 200,000 tons per year propylene plant using FMTP technology; the feasibility study has been completed and the project is now in the preliminary stage. Yuanxing Energy plans to use FMTP technology to develop a 1 million tons per year methanol-to-olefins project in Ordos, Inner Mongolia, building on its existing natural gas-to-methanol facilities. In August 2010, it signed an engineering design contract with Donghua Technology, a subsidiary of China National Chemical Engineering Group. . Note # ) # # , . hcbbs
Did the FMTP pilot plant in Huaihua cost 180 million? It is unknown how the people at Huaihua evaluate this pilot plant. No comment is made here on whether to dismantle this costly pilot plant. All I can tell you is that the MTO catalysis technology developed through the collaboration between Huaihua and the Chinese Academy of Sciences has just passed provincial-level evaluation.
Huaibei cooperating with the Chinese Academy of Sciences? Is the message reliable?
It was reported in the news. It has already passed the provincial appraisal. Anyway, Huaihua already has some kind of development in FMTP technology; you know about that
I know people from Huaihua, and I haven’t heard of them engaging in MTO activities. Do you know which institute of the Chinese Academy of Sciences they are collaborating with? Or give a link to the news, thank you
It’s not Huaihua, right? It’s Huaibei Mining Group – different, right? ? I don’t know; please don’t mislead people! ! !
Is Huaibei Mining going into MTO? That’s unlikely
Under observation; only after passing industrial application tests can a definite conclusion be drawn.
It’s the Huaibei coal mine: http://www.cnmjh.com/Article/Show.asp?ID=11472
During the first test run of FMTP at Tsinghua University, the catalyst suffered severe wear; since then, there have been no reports of any breakthroughs. There are likely major problems with their catalyst design, and without resolving this issue, no matter how good the manufacturing process may be, it will be of no use.
This is the result of decades of work by experts and academicians; there will be no problems. The problem lies with the equipment manufacturers. Moreover, to ensure success, why not buy some catalysts from UOP or from Dahuasuo first, so as to guarantee a successful commissioning of the equipment? No, leave no issues unresolved for later
