[0111] Example 1
[0112] Input 205t / h methanol as figure 2 In the shown system, the operation is carried out according to the above-mentioned operation process, wherein the flow rate of the first branch pipe 41 restricted by the first restricting flow meter 411 is 145 t / h, and the The flow rate is 56 t / h, and the flow rate on the third by-product output pipe 5 controlled by the third limiting flow meter 51 is 10 t / h, to obtain 56.8 t / h of propylene, and the yield of propylene is 27.71 wt%.
[0113] like image 3 The system of the prior art shown, the operation process is as follows:
[0114] Methanol is input into the first reactor 9' for methanol to dimethyl ether reaction to obtain the first product stream (dimethyl ether / methanol), the first product stream from the first reactor 9' is heated in the heating furnace 2' and then input into the Propylene is synthesized in the second reactor 1' to obtain the second product stream; the second product stream is input into the...
