"Carrick Process", from US Patent No. 1958918.
Pulping is a method of processing solid fuels ( coal and brown coal , shale , peat ) by heating without access to air to 500–550 ° C (the temperature is approximately two times lower than during coking ). During semi-coking, a solid combustible residue is obtained — semi-coke and volatile products. Semi-coke is used as an easily igniting smokeless solid fuel in industry and everyday life.
On the basis of semi-coke, one-component (self-caking) carbon structural materials are being developed, which in most characteristics are superior to similar two-component (based on coke and pitch ).
