催化裂化汽油临氢异构化/芳构化改质过程的反应特性
Hydroisomerization and aromatization hydro-upgrading behavior of fluid catalytic cracking gasoline
摘要
Abstract
The hydroisomerization and aromatization behavior of fluid catalytic cracking(FCC) gasoline was studied over a commercial Ni-Mo/Al2O3-HZSM-5 catalyst in a fixed bed microreactor. The effects of reaction temperature, pressure, weight hourly space velocity (WHSV), volumetric H2/oil ratio were investigated by analyzing the changes in group compositions between feedstock and products. Volumetric H2/oil ratio had negligible effect on product composition, higher reaction temperature, lower pressure and lower WHSV favored olefin aromatization, while lower reaction temperature, higher pressure and higher WHSV favored olefin isomerization. The hydro-upgraded FCC gasoline had reduced olefin content and increased isoparaffin and aromatics contents and thus had well-preserved octane rating. Lighter FCC naphtha with higher olefin content had the highest reactivity, with alpha-olefins being more reactive than internal ones and linear olefins being more reactive than branched ones.关键词
