Abstract

This project focussed on the study of the activities of different catalysts in one-step coal liquefaction processes. A series of alumina supported catalysts was prepared by multistep impregnation, including a conventional CoMo/Al(2)O(3) and other preparations containing Zn as a second promoter, and the alumina acidified with different fluorine contents. These catalysts were characterised physicochemically, and their HDS and HYD activities were tested using a model compound (thiophene). The results obtained indicate that partial substitution of Co by Zn does not affect the HDS and HYD activities and that fluorination diminishes these activities due to textural changes of the carrier.
