Process for the manufacture of a formulated oxygenate conversion catalyst, formulated oxygenate conversion catalyst and process for the preparation of an olefinic product

Abstract

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.
