摘要： The acidity of a zeolite catalyst is reduced by calcination in an essentially water-free atmosphere at temperatures above 700.degree. C., preferably from 725.degree. to 800.degree. C., to reduce the alpha value to less than about 10 percent of its original value. The low acidity catalysts produced in this way may be used for conversions requiring low acidity, shape selective catalysis, including dewaxing. The calcined, low acidity catalysts exhibit improved dewaxing activity.

摘要： A hydrocracking catalyst is provided that includes a crystalline molecular sieve material component having a faujasite structure and an alpha acidity of less than 1, preferably 0.3 or less, and a dispersed Group VIII noble metal component. The extremely low acidity allows selective hydrocracking of the aromatic and naphthenic species in a feedstock, while limiting the cracking of paraffins. The catalyst produces improved yields of products, such as diesel fuel, at high conversion rates and with high cetane values.

摘要： The present invention relates to a process for upgrading multi-branched C.sub.9 + olefinic and/or paraffinic by-products of heavy hydrocarbon upgrading processes including alkylation, polymerization, and MOGD, to high octane gasoline. Feeds rich in multi-branched C.sub.9 + olefins and/or paraffins are contacted with hydrogen at a pressure in the range of about 200 psig to about 2000 psig in the presence of an unsulfided catalyst composition comprising a low acidity molecular sieve having an Alpha Value of 5 or less. Because of the capability of the catalyst to crack at unsubstituted carbon-carbon bonds, the paraffinic products are more highly branched, and thus higher in octane number than those obtained from conventional dual function hydrocracking catalysts having Alpha Values greater than 5.
摘要翻译： 本发明涉及一种将含有烷基化，聚合和MOGD的重质烃改质方法的多支链C9 +烯烃和/或链烷烃副产物升级成高辛烷值汽油的方法。 富含多支链C9 +烯烃和/或链烷烃的进料在约200psig至约2000psig范围内的压力下在氢气存在下，在含有Alpha值为5的低酸度分子筛的非硫化催化剂组合物的存在下与氢气接触 或更少。 由于催化剂在未取代的碳 - 碳键处裂解的能力，链烷烃产物比具有α值大于5的常规双功能加氢裂化催化剂获得的链烷烃产物更高度支化，因此辛烷值高。
