PROCESS FOR PRODUCING SYNTHETIC COKING COAL OF HIGH VOLATILE MATTER CONTENT

摘要

N-4-2211GC/79ABSTRACT OF THE DISCLOSUREA process for producing a synthetic coking coal of highvolatile matter content by thermal cracking of a heavy hydro-carbon through the delayed coking process comprising heating saidheavy hydrocarbon in a furnace to a temperature between about380°C and 500°C and sufficient to initiate cracking; introducingsaid heated heavy hydrocarbon into a coking drum where it ismaintained at a temperature and for a time sufficient to effectcracking to thereby produce a thermally cracked residue havinga volatile matter content of from about 25 to 45 wt% and aGieseler fluidity of at least about 50,000 ddpm; withdrawingsaid thermally cracked residue from the coking drum at atemperature selected so as to satisfy the relation:T ? 0.293x2 - 26.12x + 790,wherein T is the temperature (°C) of the thermally crackedresidue; x is the volatile matter content of the residue (wt%)and is in the range of from about 25 to 45 wt%, and bringingsaid residue into contact with water for cooling and solidi-fication; and the synthetic coking eoal product.
