PROCESS FOR PRODUCING SYNTHETIC COKING COAL OF HIGH VOLATILE MATTER CONTENT

摘要

N-4-2211GC/79 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.degree.C and 500.degree.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 ? 0.293x2 - 26.12x + 790, wherein T is the temperature (.degree.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 eoal product.
