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