  • Patent number: 4677245
    Abstract: 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).

  • Patent number: 4311868
    Abstract: Hydrocarbon is catalytically converted by using a fluorine compound represented by the general formula Z.sup.+ MF.sub.6.sup.-, wherein Z is a hydrogen atom or a hydrogen group, and M is a niobium atom, an antimony atom or a tantalum atom as a catalyst, wherein a catalytically inactive component is settled as a heavy liquid phase or deposited as a solid in a reaction product solution from the conversion of hydrocarbon, the heavy liquid phase or the solid is removed from the reaction product solution, thereby removing substantially the catalytically inactive component therefrom, and the remaining catalytically active component is reused in the conversion of hydrocarbon. An amount of a fresh catalyst solution to be supplemented is considerably reduced by effectively reusing the catalytically active component.
