| 英文摘要 | olefin alkylation of thiophenic sulfur process was carded out in model gasoline, using ho zeolites with different si/al(2) ratios as catalysts. in particular, the influence of acid properties of h beta zeolites on its catalytic ability for the thiophene alkylation, xylene alkylation and hexene oligomerization was investigated. the results showed that the acidity of the h beta zeolite was increased with the decrease of si/al(2) ratio, but its catalytic ability was not always increased. in fact, it reached the maximal catalytic ability at si/al(2) ratio of 66, and under the reaction conditions of 60 degrees c, 1.5 mpa, whsv 3.0 h(-1) and time on stream 2 h. at the ratio, the conversion of thiophene, xylene, and oligomerized hexene were 96.6%, 2.7% and 2.8%, respectively. an optimal si/al(2) ratio exists for the catalytic performance of h beta zeolite. by investigating the coke deposition of the used h beta zeolite catalysts, it has been found that the optimal si/al(2) ratio is attributed to the combined effect of the carbocation activation capability and the hydrogen transformation capability of the h beta zeolite catalyst. |
