摘要
Abstract
The oligomerization and cracking of 1-butene were studied at various space-time,temperature and partial pressure and over HZSM-5 in an isotherm fixed-bed reactor. The results showed that increasing the space-time could improve the catalyst activity,but increased the cracking reaction and lowered the selectivity of C8. When the temperature was increased from 220℃to 410℃,the conversion of 1-butene increased first but then decreased,and the highest conversion of 1-butene was obtained at 300℃ which was explained by the 1-butene consumption rate equation. 1-Butene oligomerization was in favor of low temperature. At higher temperature cracking increased rapidly,resulting in the product distribution shifted towards lighter hydrocarbons. It was also observed that higher partial pressure increased the consumption rate of 1-butene,and therefore the oligomerization favored high partial pressure.关键词
