RI 3726 Effect of Acids and Alkalies Upon Carbonization Products of Coal

Published investigations show that many different chemical reagents have been used in determining the constitution of coals , but only a few studies have been applied directly in evaluating the effects of such reagents on the carbonization products of coal , Most of the treatments have been so drastic that any permissible conclusions that may be drawn are inferential in respect to any favorable effects on the yields and composition of the usual carbonization products .
