The aim of this study is to improvement the yields of
Malatya-Arguvan lignite liquefaction products (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.
