A research program to investigate the cause of high viscosity of coal liquefaction products and to improve this critical property was carried out at Harvey Technical Center under the joint sponsorship by Electric Power Research Institute and Atlantic Richfield Company. Prior to this joint program an in-house project was also initiated by Atlantic Richfield to determine causes and remedies for high viscosity of coal liquefaction products. One result of these programs is the discovery that certain chemical compounds, when used at concentrations of 1 to 10%, are effective in reducing the melt viscosity and softening temperature of these coal liquefaction products. These compounds can be divided into two groups, reactive and unreactive additives. Acids, anhydrides, amides and epoxides fall in the reactive group, while pyrrolidines and compounds belonging to the chemical classes of amides, phosphoramides, lactams and ketones belong to the unreactive additives. This paper summarizes findings on this subject and explains the mechanism of action involved.
