ABSTRACT:
The binderless zeolite of this invention is comprised more than 90% of crystalline aluminosilicate which is produced by crystalized a binder contained in extrudate obtained by molding a mixture of crystalline aluminosilicate and binder of silica-alumina. This binderless zeolite can improve it's catalytic activity without weaken the strength of the extrudate, since a so-called secondary pores also act as catalyst. Especially, when more than 50% of TSZ zeolite is contained, the catalytic ability of binderless zeolite is so excellent that it is preferably used as the catalyst for selective cracking of n-parafins of alkylation of aromatics using alkylation agents such as alcohols and olefins. Excellent binderless zeolite can be obtained by subjecting extrudate, formed by molding a mixture of about from 30 to 70% by weight of at least one member selected from crystalline aluminosilicate, silica alumina xerogel or hydrothermally treated silica alumina xerogel, and from 70 to 30% by weight of silica alumina gel containing from 2 to 10% by weight of alumina, under hydrothermal conditions.
