Judging from Tsinghua's patent 1144188, it is SAPO34. The product should be 60% ethylene and 25% propylene, but I don't know why it is called FMTP. Please correct me if I am wrong.
Methanol to olefins abbreviation "FMTP"”
Fluidized bed methanol to propylene, abbreviated as FMTP. The catalyst is SAPO-34
But judging from the patent, the main products are ethylene and propylene, which are similar to those of Dalian University of Technology (DMTO). It seems more appropriate to call it FMTO. I don’t know if there is another reason.
The main purpose of FMTP is propylene. It mainly returns ethylene to react again to produce propylene, thereby increasing the revenue of propylene. That’s why it’s called FMTP.
Because the cracking of C4 and above and the disproportionation of butene and ethylene to produce propylene are later added, in the end there is more propylene.
Abroad, Luqi's MTP is a fixed bed, Tsinghua's is a fluidized bed, so it is called FMTP, and MTO is both fluidized bed, Dalian's is called DMTO, and Sinopec Shanghai Research Institute's is called SMTO. The added letters seem to be for intellectual property rights!
Thank you Yiye Zhiqiu and happydays for your answers. Still have questions? don't know! Ethylene accounts for the majority of the product, but it returns to produce more propylene, which is obviously uneconomical. Whose technology is the disproportionation of butene and ethylene to produce propylene, LUMMUS’s OCT?
As mentioned on the 8th floor, Tsinghua University’s FMTP currently uses modified SAPO-34 and has completed pilot testing. However, there are currently many scientific research units studying ZSM-5, such as Lurgi's MTP. Since its pores are larger than SAPO-34, it can better utilize the generation of propylene. It has been reported that using modified ZSM-5 and a fixed production process, the single-pass propylene selectivity can be greater than 58%, and the total olefin selectivity can be greater than 79%.
Domestic, where is the fmtp catalyst produced?
Tianchen company produces FMTP catalyst
In addition to engineering design, Tianchen also produces catalysts?
