| 20090048425 | PROCESS FOR PRODUCTION OF CYCLOOLEFIN - According to the present invention, when cycloolefins are produced by partially hydrogenating a monocyclic aromatic hydrocarbon with hydrogen in the presence of a ruthenium catalyst, water, and a metal sulfate, the decrease in catalytic activity and cycloolefin selectivity is suppressed by reducing the concentration of chloride ions dissolved in the water in which the catalyst is present to 300 wt ppm or less and regenerating a part or all of the catalyst for reuse. Zinc sulfate is preferably used as the metal sulfate. Further, the raw materials and catalyst to be supplied to the reaction preferably have a reduced chloride ion content. This method can suppress the decrease in long-term catalytic activity and cycloolefin selectivity. Furthermore, the catalytic activity and cycloolefin selectivity after catalyst regeneration can be maintained at a high level. As a result, cycloolefins can be efficiently produced for a long period of time. | 02-19-2009 |
| 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 |
