Abstract:In this study, two Turkish coals, namely, Cayirhan (CC) and Kangal (KC), characterized by high levels of ash and sulfur, were co-liquefied with petroleum asphalt (Asp) at 400, 425, and 450 °C. The liquefaction/prolysis of coals and petroleum asphalt under nitrogen and hydrogen atmospheres was also performed at 400 °C. The distribution of the main product fractions (total conversion, oil, preasphaltene + asphaltene, and gas) obtained from liquefaction/pyrolysis and co-liquefaction and the detailed chemical comp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
