Claims
- 1. A process for producing a binderless zeolite catalyst which is a molded body consisting essentially of TSZ crystalline aluminosilicate, by carrying out a hydrothermal treatment of a solid prepared by molding a mixture obtained by mixing 30 to 70 weight % of at least one member selected from the group consisting of a silica/alumina xerogel, a hydrothermally treated silica/alumina xerogel and mixtures thereof with 70 to 30 weight % of a silica/alumina gel having an SiO.sub.2 /Al.sub.2 O.sub.3 ratio essentially equal to that of TSZ crystalline aluminosilicate, wherein said hydrothermal treatment is carried out in an aqueous solution in the presence of a neutral sodium salt mineralizer in a concentration ranging from 1.5 weight % to the solubility limit until the aluminosilicate content reaches essentially 100%.
- 2. A process of claim 1 wherein said hydrothermal treatment is carried out in the absence of organic cation.
- 3. A process of claim 1 wherein said molding is carried out to produce pellets, polylobal bodies, or hollow tubes.
