Sulfur present in petroleum based fuels is the main source of air pollution from exhaust emissions. For this reason, environmental regulations restrict the sulfur content of fuels to very low levels. Hydrodesulfurization is an important hydrotreating process (HDT) by which this target can be reached.  Alumina-supported Co-Mo and Ni-Mo catalysts play an important role in hydrodesulfurization of petroleum based fuels. The main objective of this research was to assess the effects of various types of aluminas on the key properties of alumina extrudates used as supports for preparing hydrotreating catalysts and to assess the effects of operating conditions during the processing of alumina on the properties of alumina extrudate.

Relation between alumina raw materials and the properties of extrudates used as support for hydroprocessing catalysts
