Better Coke by Using Antifissurants: Results for Illinois No. 6and High Splint Coals.

摘要

Illinois No. 6, a high-volatile B coal of low fluidity,was blended with fluidized-bed char and coke breeze to improve the strength of the coke obtained from carbonizing this coal. Twenty-one tests,selected from those made in the small-scale Hanson carbonizer,were carbonized in the BM-AGA 13-inch diameter,cylindrical retort,with a coal charge of about 90pounds;the strength of the cokes were determined by the standard ASTM tumbler test. Using the same procedure,ten tests were made with High Splint, a high-volatile A coal from Harlan County,Kentucky. (Author Modified Abstract)
