Abstract: A sulfuric acid alkylation process wherein acid consumption is reduced by reacting spent acid with propylene and butylene to form diisopropyl sulfate and dibutyl sulfate in an olefin absorption zone and wherein the dibutyl sulfate and diisopropyl sulfate are separately recovered in an extraction zone. The efficiency of the alkylation reaction and the quality of alkylated products are enhanced by passing the recovered dibutyl sulfates and diisopropyl sulfates to separate alkylation reaction zones.
Abstract translation: 一种硫酸烷基化方法，其中通过使废酸与丙烯和丁烯反应而在烯烃吸收区中形成二异丙基硫酸盐和二丁基硫酸盐，并且其中二丁基硫酸盐和二异丙基硫酸盐在萃取区中单独回收，从而降低酸消耗。 烷基化反应的效率和烷基化产物的质量通过将回收的二丁基硫酸盐和二异丙基硫酸盐通过分离的烷基化反应区而提高。

Abstract: Alkylation process wherein tertiary olefins are removed from a mixed olefin feed comprising tertiary and secondary olefins by catalytic polymerization and distillation, the remaining secondary olefins are reacted in excess with strong sulfuric acid until no further reaction occurs, the resulting dialkyl sulfates are extracted from the olefin-acid reaction product leaving a raffinate acid phase which is used as the catalyst for the polymerization of the tertiary olefins. The dialkyl sulfateisoparaffin extract solution and the tertiary olefin polymers are passed to a sulfuric acid alkylating zone where they are alkylated with isoparaffin.

Abstract: IMPROVED METHOD FOR RECOVERING SULFURIC ACID FROM USED SULFURIC ACID CONTAINING WATER AND HYDROCARBON WHEREBY USED ALKYLATION ACID IS BLENDED WITH SPENT ACID OF RELATIVELY HIGH HYDROCARBON CONTENT OBTAINED BY REACTING USED ALKYLATION ACID WITH AN ALIPHATIC OLEFIN TO FORM DIALKYL SULFATE WHICH IS EXTRACTED FROM THE SPENT ACID WITH ISOBUTANE. THE BLEND OF THE TWO ACIDS IS BURNED IN A SLUDGE CONVERSION PROCESS AND THE SULFUR VALUES RECOVERED AS STRONG SULFURIC ACID.
