Studies on coal-oil co-processing are one aspect of the research carried out in the field of coal liquefaction. The oil used in the process is likely to be a heavy petroleum residue due, in part, to the economic constraints of the process and, moreover, to the expected chemical compatibility. This project studies the influence of the kind of coal, vacuum residue, catalyst and temperature on the co-processing conversion and the quality of liquid products. The influence of partial pressure of hydrogen is studied. Two different Spanish lignites were co-processed with a typical commercial vacuum residue and in the presence or absence of solid catalysts. Two supported catalysts, one with 25% Fe, as oxide, and a second with 25% Fe plus 10% Mo, as oxides, were prepared. Prior to their utilization, the catalysts were sulphided
