| 英文摘要 | the preparation of light alkenes by the gas phase oxidative cracking (goc) or catalytic oxidative cracking (coc) of model high hydrocarbons ( hexane, cyclohexane, isooctane and decane in the goc process and hexane in the coc process) was investigated in this paper. the selection for the feed in the goc process was flexible. excellent conversion of hydrocarbons ( over 85%) and high yield of light alkenes ( about 50%) were obtained in the goc of various hydrocarbons including cyclohexane at 750 degreesc. in the goc process, the utilization ratio of the carbon resources was high; co dominated the produced cox (the selectivity to co2 was always below 1%); and the total selectivity to light alkenes and co was near or over 70%. in the coc of hexane over three typical catalysts (hzsm-5, 10% la2o3/hzsm-5 and 0.25% li/mgo), the selectivity to cox was hard to decrease and the conversion of hexane and yield of light alkenes could not compete with those in the goc process. with the addition of h-2 in the feed, the selectivity to cox was reduced below 5% over 0.1% pt/hzsm-5 or 0.1% pt/mgal2o4 catalyst. the latter catalyst was superior to the former catalyst due to its perfect performance at high temperature, and with the latter, excellent selectivity to light alkenes ( 70%) and the conversion of hexane (92%) were achieved at 850 degreesc ( a yield of light alkenes of 64%, correspondingly). |
