RI 5780 Correlation Of Fischer-Schrader Assay And BM-AGA Carbonization Yields ? Introduction

In 1928, the Coal Carbonization Section of the Federal Bureau of Mines, in cooperation with the American Gas Association, began a survey of the carbonizing properties of American coals. A standard test method for evaluating the carbonizing properties of coals that met the following conditions was developed: To yield products similar to those obtained in commercial operations. To produce yields sufficient to permit analyses and tests of quality. To be laboratory size. To be convenient to operate. To permit reproducible control of test conditions and results. This test method has become known as the Bureau of Mines-American Gas Association (BM-AGA) test (53),3/ and more coals of greater variety have been tested in this apparatus than in any other of similar scale.
