Phosphorus-containing zeolite catalysts and their method of preparation

A zeolite catalyst that may be used in aromatic alkylation is prepared by treating a zeolite with a phosphorus compound. The phosphorus-treated zeolite is calcined and contacted with liquid water, whereby an amount of phosphorus is removed from the phosphorus-treated zeolite. The phosphorus-treated...

Beschreibung
Zusammenfassung:	A zeolite catalyst that may be used in aromatic alkylation is prepared by treating a zeolite with a phosphorus compound. The phosphorus-treated zeolite is calcined and contacted with liquid water, whereby an amount of phosphorus is removed from the phosphorus-treated zeolite. The phosphorus-treated zeolite is then heated. A method of preparing an aromatic product may also be carried out by contacting the prepared zeolite catalyst with an aromatic alkylation feed of an aromatic compound and an alkylating agent under reaction conditions suitable for aromatic alkylation.
