Abstract

The invention is a hydrocracking process which employs a small reactor-containing hydrotreating catalyst to reduce the recombinant mercaptan content and/or smoke point of a product recovered from the effluent of the hydrocracking reactor. The entire effluent of the hydrocracking reactor is first cooled by indirect heat exchange and then passed through the hydrotreating catalyst. The effluent of the hydrotreating catalyst then continues throughout the customary cooling and separation steps employed in the product recovery system.
