The overall objectives of the contract are to investigate the fundamental problems and technical feasibility of selectively separating coal constituents and to determine the effects of the substantial removal of inorganic components or individual macerals on coal liquefaction. To achieve these aims, the following specific tasks will be undertaken: (1) procurement, characterization and storage of coals and solvents; (2) coal pretreatment; (3) characterization of size density fractions; and (4) coal liquefaction research. Over the last quarter final decisions have been made concerning the coal samples required for pretreatment and liquefaction research. Samples of -1/4'' subbituminous and bituminous coals have been obtained from the Penn State Coal Sample Bank. In addition large blocks of similar coals have been made available from which maceral concentrates will be obtained by hand-picking vitrain and fusain lithotypes. The remaining blocks of whole coal will then be used in both parts of the program. As part of a continuing literature survey on coal pretreatment methods, the results of an extensive review on oil agglomeration techniques are presented in this report. Studies have been continued in the characterization of size density fractions of an Illinois No. 6 coal sample, previously systematically reduced in size and fractionated by specific gravity. The results show additional evidence that petrographic composition can be substantially modified by the size-fractionation technique. Construction of the autoclave system is proceeding at a reasonable rate. 23 references, 2 figures, 3 tables.
