ABSTRACT:
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.
