High-volatile a bituminous coal from the Allen Mine, Las Animas County, Colorado, blended with char produced from the same coal, yielded acceptable metallurgical coke in a 500-lb movable-wall test oven. Nineteen experimental runs were carried out using several concentration levels of two different chars, 5.6 and 19.6 percent volatile matter, produced by entrainment carbonization of the base coal. With the higher-volatile char, an acceptable coke was produced at a 22.5-percent concentration; the lower volatile char did not produce an acceptable coke at the concentrations investigated.
