ABSTRACT:
A method for improving the cetane number of an aromatic hydrocarbon oil such as FCC light cycle oil and thereby increase its value as a blending stock for diesel fuel or heating oil. In one embodiment, the FCC light cycle oil is alkylated in the presence of a solid acidic catalyst and with a linear mono-olefin having a chain length of at least five carbon atoms. In another embodiment, the light cycle oil is alkylated with an olefin having three to nine carbon atoms or a mixture thereof and with ZSM-20 as catalyst to decrease the frequency of catalyst regeneration.
