【 摘 要 】

Laboratory coal liquefaction experiments were used to investigate the relationship of product distributions to the reaction variables of temperature, time, catalyst, solvent, and hydrogen availability. For reaction conditions that ensured an adequate availability of hydrogen, conversion of a bituminous coal to products (grouped into three molecular weight distributions) can be quantitatively represented by a series reaction path described by a single selectivity constant. In addition, the stoichiometry of hydrogen consumption indicated a high hydrogen uptake during the initial coal dissolution step. These results are explained in terms of a macromolecular network structure of coal.
