Title:
BINDER-FREE ZEOLITE CATALYST, PROCESS FOR ITS PREPARATION, AND CATALYTIC REACTION USING SAME
Document Type and Number:
WIPO Patent Application WO/1984/003452
Kind Code:
A1
Abstract:
Binder-free zeolite prepared by kneading and molding crystalline aluminosilicate with a silica/alumina binder and crystallizing the binder in the molding to convert 90 % or more of the whole molding into crystalline aluminosilicate. The obtained binder-free zeolite shows an improved catalytic effect without reducing the strength of the molding since so called secondary fine pores effectively show a catalytic action. Particularly good performance can be obtained when 50 % or more of the crystalline aluminosilicate is TSZ crystalline aluminosilicate, and this catalyst is excellent as a catalyst for selective cracking of n-paraffin hydrocarbons and as catalyst for aromatic alkylation with an alkylating agent such as an alcohol or olefin. Good binder-free zeolite can be obtained by kneading and molding a mixture of 30 to 70 wt % of one or more members selected from among crystalline aluminosilicate, silica/alumina xerogel, and hydrothermally treated silica/alumina xerogel and 70 to 30 wt % of silica/alumina gel containing 2 to 10 wt % alumina, and hydrothermally treating the molding.
