Production of high cetane diesel fuel by employing hydrocracking and catalytic dewaxing techniques

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° F. (205° C.) and 1000° F. (538° C.) is subsequently catalytically dewaxed in order to obtain a cloud point of no more than 41° F. (5° C.). The hydrocracker effluent fraction is preferably recycled to the hydrocracking step prior to dewaxing.
