    摘要: A surface-inactivated catalyst composition comprising acidic porous crystalline material, e.g., ZSM-23, having active internal Bronsted acid sites and containing coke-inactivated external acid sites is prepared by contacting the catalyst under high pressure coking conditions, e.g. 800 psig. The catalyst may be used for organic compound conversion, e.g., oligomerization of lower olefins to produce distillate boiling range materials having reduced methyl branching and increased cetane number.

    摘要: A process for the production of diesel fuel with a high cetane number at a low cloud point, which involves hydrocracking highly aromatic fractions obtained from catalytic cracking operations. The fraction of hydrocracker effluent which boils between about 400.degree. F. (205.degree. C.) and 1000.degree. F. (538.degree. C.) is subsequently catalytically dewaxed in order to obtain a cloud point of no more than 41.degree. F. (5.degree. C.). The hydrocracker effluent fraction is preferably recycled to the hydrocracking step prior to dewaxing.
