    摘要: A novel hydrocarbon alkylation process is disclosed wherein the feed hydrocarbons are dried to maintain the water content of the alkylation catalyst at less than 2.0 wt. %, where said alkylation catalyst is comprised of a mineral acid and an ether component selected from the group consisting of tert-butyl ether, methylphenyl ether, tert amylmethyl ether (TAME), or methyl tert-butyl ether (MTBE). This process also incorporates a method of regenerating at least a portion of the alkylation catalyst to prevent build-up of more than 15 wt. % of polymer products therein.

    摘要: Olefins containing from 2 to about 6 carbon atoms may be directly hydrated by treatment with water in the presence of a catalyst comprising an alpha-zirconium phosphate. The use of this catalyst which possesses desirable thermal stability characteristics will enable the reaction to be effected at higher operating conditions than is possible when utilizing other catalysts.
