Abstract
The blending of carbonaceous materials, particularly Pennsylvania anthracite, with coking coals as a means of mitigating the acute war shortage of certain types of metallurgical coke, has received considerable emphasis in recent months. However, the desirability of blending anthracite fines with coking coals for by-product coke production has been a matter of considerable controversy. To settle the differences of opinion and judgment, an attempt has been made as reported in this paper to evaluate, at least relatively, some of the variables encountered in the case of anthracite fines. The investigation in question was conducted at the Mineral Industries Experiment Station of The Pennsylvania State College, and was sponsored jointly by the Anthracite Institute and the Commonwealth of Pennsylvania.
