设计了一种带有内部传质结构的高比表面积管式反应器，通过混合实验验证了其混合效果达到并优于STRATCO反应器。在管式反应器系统上考察了烷烯摩尔比、反应温度、停留时间和酸烃摩尔比对三甲基戊烷（TMP）选择性的影响，优化得到管式C₄烷基化反应最佳的工艺参数条件。当烷烯摩尔比为15：1、温度为10℃、停留时间为5 s、酸烃摩尔比为1：1时，反应转化率≥ 99%，TMP的选择性达到64.2%，主要技术经济指标达到了STRATCO工艺的水平。

A high specific surface area tubular reactor with an internal mass transfer structure is designed and verified through mixing experiment to achieve better mixing effect than STRATCO reactor.The effects of alkane/olefin ratio,reaction temperature,residence time and sulfuric acid/hydrocarbon ratio on the selectivity of trimethyl pentane (TMP) are investigated in above tubular reactor system,and the optimal process parameters are obtained for the tubular C₄ alkylation reaction.The reaction conversion rate can exceed 99% and the selectivity to TMP can reach 64.2% when the alkane/olefin ratio is 15:1,the temperature is at 10℃,the residence time is 5 seconds and the ratio of sulfuric acid to hydrocarbon is 1:1.The main technical and economic indexes can reach the level of STRATCO technology.
