Abstract: 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.
