Abstract: A process is disclosed for manufacturing solid fuel which includes the steps of mixing a biomass, a heavy hydrocarbon and a sorbent to form a hydrocarbon-biomass slurry, the biomass being characterized by a particle size and distribution of about 50% between about 250-2000 .mu.m and about 50% less than about 250 .mu.m, and more preferably as follows:______________________________________ distribution particle size ______________________________________ 10-20% 1250-2000 .mu.m 10-20% 500-1250 .mu.m 10-20% 250-500 .mu.m balance .ltoreq.250 .mu.m ______________________________________compacting the slurry to form a solid fuel agglomerate; and baking the agglomerate so as to form a solid fuel briquette having a resistance to compression of at least about 22 kg/cm.sup.2. The mixing step includes the step of mixing the biomass, hydrocarbon and sorbent in the following proportions, by weight: ______________________________________ biomass 50-70%; hydrocarbon 30-45%; and sorbent 5-10%.
