Abstract
The invention relates to a molecular sieve catalyst composition, to a method of making or forming the molecular sieve catalyst composition, and to a conversion process using the catalyst composition. In particular, the invention is directed to making a formulated molecular sieve catalyst composition from a slurry of formulation composition of a synthesized molecular sieve that has not been fully dried, a binder and an optional matrix material. In a more preferred embodiment, the weight ratio of the binder to the molecular sieve and/or the solid content of the slurry is controlled to provide an improved attrition resistant catalyst composition, particularly useful in a conversion process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, preferably an oxygenate containing feedstock.
