摘要： A process for catalytically converting cyclohexanone oxime to epsilon caprolactam. The conversion catalyst is a crystalline aluminosilicate zeolite having a Constraint Index greater than 1 and a reduced surface acidity. The surface acidity is reduced by selective surface dealumination of the crystalline aluminosilicate zeolite by contacting the zeolite with dicarboxylic acid, such as oxalic acid.

摘要： A method for skeletal isomerization of linear olefins to iso-olefins, e.g., n-butenes to isobutylene, over a catalyst comprising medium pore zeolite, e.g., a zeolite selected from ZSM-22, ZSM-23, and ZSM-35. Treatment of the zeolite with dicarboxylic acid, e.g., oxalic acid, significantly reduces aging rate and increases cycle length of the catalyst.

摘要： There is provided a process for regenerating a coked catalyst comprising a zeolite and a noble metal such as platinum. The process involves treating the coked catalyst under somewhat mild oxidation conditions, whereby a sufficient portion of the coke is removed from the catalyst to restore the hydrocarbon sorption properties of the zeolite component to the level observed in the non-coked form. Surprisingly, the original activity of the catalyst is substantially restored, even though a substantial amount of coke remains on the regenerated catalyst.

摘要： A method for producing substantially linear hydrocarbons by oligomerizing a lower olefin at elevated temperature and pressure which comprises contacting the lower olefin under oligomerization/polymerization conditions with constrained intermediate pore siliceous acidic zeolite, e.g., ZSM-22, -23 or -35, having Bronsted acid activity; wherein the zeolite has acidic pore activity and wherein the zeolite surface is rendered substantially inactive for acidic reactions. The zeolite surface can be inactivated by contact with dicarboxylic acid, e.g., oxalic acid. The olefin oligomers may be used as alkylating agents to prepare biodegradable alkylbenzenes and alkylphenylsulfonates.

摘要： A process for producing high quality lubricants by the hydrocracking and hydroisomerization of petroleum waxes uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material exhibits unusually large pores of at least 13 .ANG. diameter and a high sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than about 18 .ANG. and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 .ANG. diameter which can be indexed with a d.sub.100 value greater than about 18 .ANG.. The hydrocracking catalysts based on these materials are capable of producing lube products with a high VI of at least 120 and usually higher, values of 135 and higher e.g. 143. the lube products are produced in good yield from feeds which may contain down to about 30 percent wax content, although wax contents of at least 50 percent are preferred for the highest quality products. The catalysts achieve this result without the use of fluorine or other promoters.

摘要： The equilibration of a zeolitic hydrocracking catalyst is accelerated by the addition of nitrogen compounds to the hydrocracker feed during the start of cycle (SOC). Addition of the nitrogen compounds reduces the exotherm, indicative of a decrease in the hydrogenation activity of the catalyst consequent upon the addition of the nitrogen. The reduced hydrogenation level decreases hydrogen consumption at this point in the cycle so that units which are hydrogen constrained may be operated under more favorable conditions. In addition, the attainment of equilibrium or lineout conditions is accelerated and yield benefits, particularly in the production of middle distillates are observed.
摘要翻译：沸石加氢裂化催化剂的平衡通过在循环开始（SOC）期间向加氢裂化器进料中加入氮化合物来加速。氮化合物的添加降低了放热，表明随着氮的加入，催化剂的氢化活性降低。降低的氢化水平降低了循环中此时的氢消耗，使得氢受限的单元可以在更有利的条件下操作。此外，达到平衡或排水条件得到加速，产量有利，特别是在中间馏分的生产中被观察到。
