| 英文摘要 | by analyzing the reaction process and calculating the thermodynamics of each reaction in butene catalytic cracking combining the factual product distribution, the formation mechanism of each product and its influence factors have been studied. the calculated equilibrium constants showed that high temperature favored c4h8 cracking to c3h6 and c2h4, but relatively low temperature and high pressure were needed in order to increase the molar ratio of c3h6/c2h4 in the products. the equilibrium constants of alkene hydrogen transfer and oligomerization-dehydrocyclization-aromatization reaction were 10 similar to 1000 times as high as those of c4h8 cracking to c3h6, which implied that it was favorable to form aromatics and low carbon alkanes under the cracking conditions compared with c3h6 and c2h4 production. in order to suppress the formation of aromatics and low carbon alkanes dynamically, it was very important to develop catalysts with high selectivity for c3h6 and c2h4, and to optimize reaction conditions such as relatively high whsv and high temperature. in the mean time, the amount of c5+ hydrocarbons was in a low level under the catalytic cracking conditions. the thermodynamics result was confirmed and supplemented by its application in catalyst design and reaction condition optimization during butene catalytic cracking to c3h6 and c2h4. |
