Drying of lignite coal had considerable influence on the coal liquefaction conversion. Vacuum dried and nitrogen dried samples provided higher conversion than air dried samples. The air drying showed nearly lower conversion, which probably as a result of oxidation. Air Drying … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 12 Mar 2019 · 7,868 accessesView PDFCite
