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: - treating with a phosphorus containing compound a first molecular sieve comprising aluminosilicate and a second molecular sieve, different from the first molecular sieve, the second molecular sieve having more- dimensional channels; and - combining the first molecular sieve, the second molecular sieve and a matrix material; wherein the catalyst is not treated 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.
