Abstract
Official abstract text for this publication.
The present invention provides a zeolite-containing catalyst having excellent shape, fluidity and mechanical strength as a catalyst for a fluidized bed reaction. The present invention provides a zeolite-containing catalyst which is a particulate catalyst containing zeolite and silica, wherein the catalyst has an average particle diameter of 20 to 300 μm and the ratio of the void area in the cross-section of the particle is 30% or less relative to the cross-section area of the particle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a zeolite-containing catalyst, wherein the zeolite is an MFI-type zeolite, comprising: the steps of obtaining a dried powder by spray drying a raw material mixture containing zeolite and colloidal silica; and calcining said dried powder to obtain a particulate catalyst comprising an MFI-type zeolite and silica, wherein said raw material mixture contains at least one water-soluble compound selected from the group consisting of a ni…
