A Victorian brown coal (VBC) has been heated with strong aqueous KOH under severe conditions, neutralized with dilute H2SO4 and then hot-briquetted with or without coking coal tar pitch as a binder, optionally air cured and finally carbonized. The final products were evaluated as a blast furnace (BF) coke substitute. The least reactive final product had a much lower reactivity than the product obtained...
The products obtained by carbonization of a mixture of hydrothermally dewatered acid washed Victorian brown coal and coking coal tar pitch, which had been briquetted at 150 or 230°C and air cured were shown to approach blast furnace (BF) coke in many of their properties. The samples had higher strength than BF coke and showed surface areas and reactivities much closer to those of a typical BF coke...
Attempts have been made to obtain a substitute for blast furnace (BF) coke from a Victorian brown coal mixed with a tar derived from brown coal under conditions sufficiently mild to be economical. Changes to the procedure used in a previous attempt include hot briquetting of the coal–tar mixture at 150°C rather than ambient, the addition of air curing at 200°C and carbonization at higher temperature,...
This paper describes attempts to produce blast furnace coke from Victorian brown coals. The attempted method involves combining a coal-derived binder with the original brown coal or its commercial products, briquettes. Briquetting of these mixtures gave composites that were then carbonized to form coke-like materials. Products were characterized by bulk density, helium density, compressive strength,...
