CATALYST PARTICLES, PROCESS FOR THE PREPARATION OF AN OLEFINIC PRODUCT, AND PROCESS FOR THE PREPARATION OF AN OXYGENATE CONVERSION CATALYST

摘要

Catalyst particles comprising a first molecular sieve having one-dimensional 10-membered ring channels, and a second molecular sieve having more-dimensional channels; a process for the preparation of such catalyst particles; and a process for the preparation of an olefinic product, comprising reacting an oxygenate feedstock in a reaction zone in the presence of catalyst particles of the invention.
