Process for producing synthetic coking coal of high volatile matter content
A process for producing a synthetic coking coal of high volatile matter content by thermal cracking of a heavy hydrocarbon through the delayed coking process comprising heating said heavy hydrocarbon in a furnace to a temperature between about 380/sup 0/ C and 500/sup 0/ C and sufficient to initiate cracking; introducing said heated heavy hydrocarbon into a coking drum where it is maintained at a temperature and for a time sufficient to effect cracking to thereby produce a thermally cracked residue having a volatile matter content of from about 25 to 45 wt % and a gieseler fluidity of at least about 50,000 ddpm; withdrawing said thermally cracked residue from the coking drum at a temperature selected so as to satisfy the relation: T < or = 0.293x2-26.12x+790 where T is the temperature (/sup 0/C.) of the thermally cracked residue; X is the volatile matter content of the residue (Wt %) and is in the range of from about 25 to 45 wt %, and bringing said residue into contact with water for cooling and solidification; and the synthetic coking coal product.
