PROCESS FOR THE PRODUCTION OF ASHLESS LIQUID FUELS

摘要

PROCESS FOR THE PRODUCTION OF ASHLESS LIQUID FUELS An ashless liquid fuel of good quality is produced by combining powdery coal with a heavy oil of the petroleum series in an amount of at least 50 parts by weight of heavy oil per 100 parts by weight of the powdery coal, subjecting the mixture to a heat treatment conducted at 400-450.degree.C and thereafter, removing a solid coagualted material formed in the treated product. An especially good result is obtained when a heavy oil of petroleum series having an atomic ratio C/H of at least 0.9 is used.
