Alkaline phosphate-activated clay/zeolite catalysts |
摘要 |
Zeolite/clay/phosphate catalysts can be prepared by a process wherein a composition of zeolite-clay-phosphate is brought to a pH level of about 7.0 to about 14.0. The resulting slurry is then age reacted for about 0.5 to about 24 hours. Thereafter the slurry is dried to produce a zeolite/clay/phosphate catalyst particles that are particularly characterized by their high levels of zeolite stability.
