| titleOfInvention | Semi-continuous method for converting methyl alcohol into propylene by using moving bed technology |
| abstract | The invention discloses a semi-continuous method for converting methyl alcohol into propylene by using a moving bed technology, which comprises the following steps: mixing a molecular sieve based catalyst with a diluent, and then, introducing into a first reaction zone; introducing a methyl alcohol raw material into the first reaction zone to generate contact reaction with the molecular sieve based catalyst to generate a first material flow; introducing the first material flow into a second reaction zone to generate the contact reaction with the molecular sieve based catalyst to generate a second material flow; after the second material flow and the methyl alcohol raw material exchange heat and after dehydration and oxide removing are carried out, carrying out separation to obtain a second reaction zone return, a second reaction zone discharge and a third reaction zone feed, and merging the second reaction zone return into the first material flow; introducing the third reaction zone feed into a third reaction zone to be contacted with the molecular sieve based catalyst to generate a third material flow; and conveying the molecular sieve based catalyst into a regenerating unit at regular intervals by adopting a catalyst collector for regeneration, and intermittently merging into the molecular sieve based catalyst for circulation. Three stages of reaction of the methyl alcohol into the propylene are realized only by one molecular sieve based catalyst, thereby, the propylene yield is improved. |
