ABSTRACT:
Hydrodenitrogenation of high nitrogen content hydrocarbon feeds comprises contacting the feed with hydrogen under hydrodenitrogenation conditions in the presence of a multiple catalyst system comprising an initial catalyst of apparent higher order reaction kinetics and lower rate constant for hydrodenitrogenation followed by at least one subsequent catalyst of apparent lower order reaction kinetics and higher rate constant for hydrodenitrogenation.
