摘要: A hydrogenation process for reducing the unsaturation of lubricants uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material has pores of at least 13 Å diameter arranged in a uniform manner and exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams (50 torr and 25 °C). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern that can be indexed with a d100 value greater than about 18 Å. The hydrogenation catalysts based on these materials are capable of reducing the unsaturation in poly alpha olefin lubricants to a low level.

摘要: A catalytic process for the treatment of exhaust containing NOx along with other undesirable compounds is described. One embodiment of the process comprises a catalytic stage to selectively catalytically reduce NOx over an intermediate pore size zeolite catalyst that has been treated or modified to contain iron and then has been hydrothermally treated at least one time.

摘要: This invention relates to the catalyst composition resulting from the addition of phosphorus, and optionally, a matrix material, to a porous crystalline material having the structure of MCM-22. The addition of phosphorus to the MCM-22 is found to improve the hydrothermal stability of the resulting catalyst. The improved catalyst is useful in organic conversion processes, e.g., catalytic cracking processes.
