The principal objective of this research is to determine the role that host petroleum-derived oils (1000 {degree}F{sup +}), as that of catalytically treated host oils, play when used as liquefaction solvents in coprocessing with coal. The host oils will be extensively characterized and then pretreated in a number of ways which involve catalytic reactions such as hydrogenation, hydrocracking, and isomerization. The pretreated oils will then be characterized by elemental analysis, catalytic dehydrogenation, and NMR. The effects of the host oil on coprocessing with coal will be compared to those obtained using catalytically modified heavy oils. When appropriate, model compounds will be used to study specific reactions brought about by the pretreatments. A total of 18 pretreatment runs have been made on an AMOCO vacuum tower residuum, VTR, in an attempt to increase its hydrogen content from 10.2 wt % to a level of about 11.5%. This pretreatment resulted in a significant increase in the hydrogen content of the starting oil (10.2 wt % to 11.2%).
