  • Method of preparing a modified zeolite catalyst and preparing ethylbenzene using one cycle process
    Patent number: 10927055
    Abstract: The invention provides a modified zeolite, a method of preparing the modified zeolite and a method of one cycle alkylating benzene in presence of one of an unmodified and modified zeolite catalyst. The modified zeolite catalyst includes zeolite with ratio of silica to alumina ranging between 5% to 95% of silica and 95% to 5% alumina, kaolinite and a binder, wherein the zeolite is modified with one or more metal oxides of Lanthanide-series of the Periodic Table. The method of alkylating benzene is one cycle process in presence of a catalyst that includes charging benzene and ethylene gas feedstock to an alkylation zone. Heated benzene and the ethylene gas feedstock are contacted in a fixed bed reactor in the alkylation zone. The catalyst for alkylating benzene is added in a catalyst zone of the fixed bed reactor.
