ABSTRACT:
A method is provided for preparing a synthetic crystalline aluminosilicate zeolite Alpha containing platinum-group metal within the zeolite pores as synthesized, thereby providing shape-selective hydrogenation activity. The method comprises synthesizing the zeolite from a reaction mixture of controlled composition including a source of a cationic platinum-group metal complex. Catalysts made with the zeolite synthesized in accordance hereto are stable, both thermally and in the presence of steam, and exhibit beneficial shape-selectivity in catalysis and absorption.
