This paper reports an excellent performance of pyrenes and fluoranthenes hydrogenated with Li-ethylenediamine or a Ni-Mo catalyst to produce hexane soluble as well as benzene soluble products from the brown coal under the short contact time conditions at further high temperature and a low pressure, the former of which was attained within 1. 5 min. Roles of hydrogen reactivity of the solvent are briefly discussed in such a liquefaction process.
