The coal liquids were stable while the petroleum crude oils showed some measure of instability. Instability in the coal liquid/petroleum crude oil blends was accounted for by the instability of the petroleum curde oil. Blending of the coal liquids/petroleum crude oil revealed no adverse effects in co-processing. Studies were undertaken to measure the economic impact on a typical Gulf CCoast refinery of introducing varying quantities of H-Coal liquid to replace equivalent amounts of imported crude oil. The use of both raw and hydrotreated coal liquids was investigated. When even small amounts of raw coal liquid were introduced, the need for a new naphta hydrotreater became apparet because of the nitrogen and olefins present in the naphtha. As greater portions of raw coal liquid were added, other specified limitations were reached. When imported crude oil was replaced by hydrotreated H-Coal liquid, fractionation limitations were essentially the same as for the raw coal liquids cases. The processing of additional quantities of coal liquids (raw or hydrotreated), replacing imported crude, had no great effect on product slate or refinery economics. The derived maximum values which a refiner could afford to pay for raw or hydrotreated coal liquid and still maintain his profit were nearly the same in each cast. Intuitively, however, one would assume that hydrotreated coal liquid would cost more. These conclusions are subject to confirmation by definitive studies of the stability of fresh raw coal liquid and its compatibility with crude oil.
