| Abstract: | The control program of methanol dewatering tower was improved,and the catalyst activating conditions such as temperature,time and air quantity as well as reactive temperature were optimized.Based on above works,the process flow of isobutene production by methyl tert-butyl ether cracking was changed from one-reactor-six-tower to one-reactor-three-tower system.The results showed that the methanol yield increased from 30.08% to 33.47%,the isobutene yield increased from 54.01% to 58.14%,and the engery consumption of the device reduced from 8648.76MJ/t to 5863.15MJ/t. |
