Abstract

A method for manufg. briquet using low quality coals, esp. waste coals (A) was described. Dired rice bran or sawdust was carbonized at 120-220≰C for 125-140 min under oxygen-free condition to give carbonized powders(B). A soln. where 1:1 (Fe2O3:B2O3) mixture coexisted with 20% calcium acetate soln. was spay dried onto B to give C. The briquet with >=4500 Cal was manufd. by mixing 10-15wt.% (based on A) C and A, and molding.
