Abstract

This paper presents the results of thermal (with no added catalyst) coprocessing of Illinois No. 6 (hvBb) coal with two different petroleum host oils — Maya (650°F+) ATB residual oil and with whole Boscan crude. The relationship between reaction conditions and coal conversion and product selectivity has been studied. The removal of vanadium during coprocessing has been investigated. Supressed removal of sulfur and nitrogen was achieved in coprocessing compared to heteroatom removal when Maya ATB was processed in the absence of coal.
