ABSTRACT:
Problems associated with the formation of polycyclic aromatic compounds within hydrocracking reaction zones are reduced by a feed pretreating sequence which comprises first contacting the feed with a metal-free alumina to produce polycyclic compounds or their precursors followed by their removal by contacting the feed with a bed of adsorbent such as charcoal. The feed pretreatment steps are operated at an elevated temperature but at a very reduced pressure and preferably substantially free of hydrogen.
