Exploratory runs were continued in an attempt to determine reaction conditions which would produce results representative of those obtained in a flow reactor at Wilsonville, Alabama. Since earlier results indicated a possible mass transfer limitation of hydrogen from the gas to the liquid phase, a larger impeller was installed in the batch reactor used in this work. This reactor modification has increased the extent of the coal liquefaction approximately 10 wt percent at the same reaction conditions, and thus provides results within the range obtained at Wilsonville. Solvent balance remains a problem. Work is proceeding satisfactorily toward developing procedures for analyzing nitrogen types in the liquefaction product. Progress has also been made in developing techniques for analyzing tetralin type and phenol type compounds in the solvents to be used.
