Abstract: A novel catalyst and the use thereof in a reforming process is disclosed. The catalyst comprises a refractory inorganic oxide, platinum-group metal, Group IVA(IUPAC 14) metal, indium and lanthanide-series metal. Utilization of this catalyst in the conversion of hydrocarbons, especially in reforming, results in significantly improved selectivity to the desired gasoline or aromatics product.

Abstract: An alkylating agent alkylates an alkylation substrate in a solid catalyst alkylation process in which an alkylation reactor produces a reaction effluent and a catalyst regeneration zone produces a hydrogen-containing regeneration effluent. The alkylation effluent passes to an alkylate fractionation zone, while the regeneration effluent passes to a hydrogen fractionation zone to remove hydrogen and produce a hydrogen-depleted stream that passes to the alkylate fractionation zone. The process recycles hydrogen, and can recycle halogen-containing species as well, within the process while preventing admixture of hydrogen with the alkylating agent. This invention is particularly applicable to alkylation processes that use an olefinic alkylating agent.
