20080269436 | Molecular sieve catalyst composition, its making and use in conversion processes - 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. | 10-30-2008 |
20090082545 | Method Of Formulating A Molecular Sieve Catalyst Composition By Controlling Component Addition - This invention provides a method of making a molecular sieve catalyst composition comprising the steps of: a) combining molecular sieve crystals with binder and liquid to form a binder-sieve mixture; b) combining the binder-sieve mixture with matrix material to form a binder-sieve-matrix mixture; c) mixing the binder-sieve-matrix mixture under conditions sufficient to form a slurry having a solids content of at least 40 wt %, based on total weight of the slurry; d) progressing the mixing until slurry viscosity decreases without significant additional dilution of the slurry, so that the slurry solids content does not significantly decrease; and e) drying the decreased viscosity slurry to produce a dried molecular sieve catalyst composition having an attrition rate index of not greater than 1 wt %/hr. The aforementioned catalyst compositions can be used in processes for making olefin product from oxygenate feedstock, which olefin products can be further used for making (co)polymer products. | 03-26-2009 |
