Book Description
Excerpt from Solvent Extract and the Plastic Properties of Coal Because the earlier work had covered studies on only three samples of coal, we decided to extend it to cover more coals of various ranks, volatile matter con tents, and maximum fluidity levels. This report presents the results of these extended studies. In this work emphasis was placed on the relationship of quan tity of extract to maximum fluidity and on the maximum fluidities of blends made by combining extracts and residues in different proportions Chemical analyses for coals, extracts, and residues are presented, and, in addition, molecular weight data are given for the pyridine extracts and fractions thereof derived by further solvent treatment.

Book Description
Increased liquefaction yield is obtained by pretreating a slurry of solid carbonaceous material and a liquid hydrocarbonaceous solvent at a temperature above 200.degree. C. but below 350.degree. C. for a period of 10 minutes to four hours prior to exposure to liquefaction temperatures.

Book Description
A method for the hydroconversion of coal by solvent treatment at elevated temperatures and pressure wherein an alcohol having an .alpha.-hydrogen atom, particularly a secondary alcohol such as isopropanol, is utilized as a hydrogen donor solvent. In a particular embodiment, a base capable of providing a catalytically effective amount of the corresponding alcoholate anion under the solvent treatment conditions is added to catalyze the alcohol-coal reaction.
