ZEOLITE CATALYST MANUFACTURE

摘要

CATALYST MANUFACTURE Attract Zeolite containing catalysts are prepared by forming and drying an aqueous slurry of zeolite, aluminum chlorhydrol and clay to obtain particulate composites that contain in excess of about 1 percent by weight alkali metal oxide. The particulate composites are calcined and subsequently ion exchanged to obtain hard, attrition resistant catalyst particles which have an alkali metal oxide content of less than 1 percent by weight.
