| In this study, hydrodesulphurization (HDS), hydrodenitrogenation (HDN), hydrodemetallization (HDM), and micro carbon residue (MCR) removal were investigated using residuum hydrocracking catalysts containing a zeolite component. The first family of catalysts containing H-mordenite was tested at a pressure of 13.9 MPa and at temperatures of 400 and 450;Benzofuran temperature programmed desorption (TPD) measurements showed that, the number of acid sites increased with increasing zeolite (H-mordenite or HY) content in the catalysts.
