On the technical implementation of DMTO-II

It’s not a shared reactor; components with a molecular weight of C4 or higher are considered heavy fractions, which are subjected to pyrolysis in a separate cracking vessel. The resulting products are then mixed directly with the gases coming from the reactor and sent on to the next distillation stage
Reply to 2# Fake smile? Can you give a specific reason? !
Reply to 2# Fake Smile: I also have another question – how is heat coupling achieved in that case?
Reply to 3# Du Haichuan: The catalysts are different
Both MTP and MTO are exothermic reactions, while cracking is endothermic; furthermore, PP and PB are also exothermic reactions. Overall, there is definitely an excess of heat.
In the domestic DMTO-II technology, a single reactor is shared for methanol production, but it can be said that this approach has some drawbacks.
DMTO2: How can the heat generated by the reactor be utilized to heat the cracking reactor?
Reply to 7# chqi527: Could you explain it in more detail?
Reply to 5# Fake Smile: The catalysts should be the same, as they are all catalysts developed through the collaboration between Dahuahua and CP Group
