摘要：

Influence of pretreatments, i.e., demineralization and pre-soaking in some solvents on the yields of liquefied products obtained from hydro-depolymerization of Pakistani coal in a pool of hydrogen has been discussed. Results of hydrogenation experiments demonstrated that demineralizing the coal sample prior to liquefaction caused the yields to decrease compared with the Virgin coal samples. The contribution of mineral matter of coal has been evaluated by comparing the yields of liquid products Of Virgin and leached samples. Increase in the yields obtained from the hydrogenation experiments of swollen coal samples was not satisfactorily significant.
