    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 .ANG. 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.degree. C.). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG.. The hydrogenation catalysts based on these materials are capable of reducing the unsaturation in poly alpha olefin lubricants to a low level.

    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, along with the method for making the catalyst composition, and the method for using the catalyst composition in catalytic cracking. It is desirable to improve the hydrothermal stability of the catalysts which are based upon porous crystalline materials having the X-ray structure of MCM-22 to increase the activity that the catalyst maintains after repeated cycles of steaming such as is experienced in the FCC process. It has been found that phosphorus addition to a porous crystalline material having the structure of MCM-22 improves the hydrothermal stability of the resulting catalyst. This improved catalyst is useful in organic conversion processes, e.g., catalytic cracking processes.

    摘要： Akylation product is contacted with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream may then be further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound to a monoalkylated aromatic compound. The process may use a large pore molecular sieve catalyst such as MCM-22 as the purification medium in the pre-reaction step because of its high reactivity for alkylation, strong retention of catalyst poisons and low reactivity for oligomerization under the pre-reactor conditions. Olefins, diolefins, styrene, oxygenated organic compounds, sulfur containing compounds, nitrogen containing compounds and oligomeric compounds are removed.
