该专利涉及一种汽油烷基化脱硫的催化蒸馏方法。将含硫汽油加入到催化蒸馏塔内,在固体酸催化剂作用下,汽油中的烯烃与硫化物发生烷基化反应,生成更高沸点的含硫化合物。将柴油或高沸点烃油与汽油共同在蒸馏塔中进行分馏,通过分馏作用将高沸点的含硫化合物从汽油转移到柴油或高 This patent relates to a gasoline catalytic alkylation desulfurization distillation method. The sulfur-containing gasoline is added to the catalytic distillation tower. Under the action of the solid acid catalyst, the olefins in the gasoline are alkylated with the sulfides to generate higher-boiling sulfur-containing compounds. Diesel or high-boiling hydrocarbon oils are co-fractionated with gasoline in a distillation column, the high boiling point sulfur-containing compounds are shifted from gasoline to diesel or high by fractional distillation
