Abstract :The aim of this study is to improvement the yields of Malatya-Arguvan lignite liquefaction products insert ignore into journalissuearticles values(char, preasphaltene, asphaltene, oil-gas);. For this purpose, the liquefaction experiments of coal which firstly raw and then enriched by spiral have been carried out. The chemical characterizations of the obtained products were determined by proximate and ultimate analysis. The composition of the oil was identified by GC-MS. As a result of the enrichment, the char yield decreased by 9.28% whereas the preasphaltene yield increased by 5.31% and the oil + gas yield increased by 4.18%. Total conversion increased from 47.57% to 56.85%. It has been concluded that the enrichment process has a positive effect on the liquefaction yields.
