PROCESS FOR THE MANUFACTURE OF A FORMULATED OXYGENATE CONVERSION CATALYST FORMULATED OXYGENATE CONVERSION CATALYST AND PROCESS FOR THE PREPARATION OF AN OLEFINIC PRODUCT

摘要

The present invention provides a process for the manufacture of a formulated oxygenate conversion catalyst the process comprising combining a first molecular sieve comprising aluminosilicate a second molecular sieve different from the first molecular sieve the second molecular sieve having more-dimensional channels and a matrix material; and treating the catalyst with a phosphorus containing compound after combination of the molecular sieves with the matrix material. In a further aspect the invention provides a formulated oxygenate conversion catalyst and a process for the preparation of an olefinic product.
