Patent number: 5464593Abstract: A process for producing a spherical zeolite catalyst is disclosed, which comprises dropping a zeolite-containing alumina sol into a surfactant-containing oil phase from a dropping opening directly or through air to thereby form spherical droplets of the sol, and then allowing the droplets to gel in an aqueous alkaline solution phase underlying the oil phase and withdrawing the thus gelled droplets, said dropping of the sol being conducted while the dropping opening is being impulsed to thereby impart a spherical and uniform shape to the resulting zeolite particles containing alumina as a binder, and a novel apparatus therefor.Type: GrantFiled: July 12, 1994Date of Patent: November 7, 1995Assignees: Mitsubishi Oil Co., Ltd., Chiyoda CorporationInventors: Kazuo Takahashi, Fumio Kumata, Hitoshi Nozaki, Shinichi Inoue, Toshiji Makabe
