| titleOfInvention | Method for controlling temperature of multistage moving-bed reactor |
| abstract | The invention discloses a method for controlling the temperature of a multistage moving-bed reactor applied to a technology for preparing propylene by methanol, the method comprises the following steps: 1) dividing the product flow from a dimethyl ether reactor into two streams, wherein one stream of the product flow is used for directly feeding of a multistage moving-bed MTP reactor, other stream of the product flow is divided into a plurality of streams which are being used for feeding of the temperature controlling of the multistage moving-bed MTP reactor; 2) reducing the temperature of the feeding stream controlled by the temperature through the heat comprehensive utilization; 3) introducing the interstage high temperature reaction gas of the multistage moving-bed MTP reactor, mixing the reaction gas with the low temperature feed stream used for controlling the temperature in an interstage treating zone out of the reactor; 4) mixing the cooled material to send to a next stage moving-bed MTP reactor for continuously participating in a conversion reaction until the material is discharged at a final stage. The method for controlling the temperature of the multistage moving-bed reactor of the invention is capable of effectively removing the strong reaction heat discharged from the reactor, stabilizing the reaction temperature in the multistage moving-bed reactor and realizing the purpose of raising the yield of propylene finally. |
