Purpose of I nvestigation. This bulletin is a report of work carried on under a cooperative agreement participated in by the Illinois State Geological Survey Division, the Engineering Experiment Station of the University of I llinois, and the U. S. Bureau of Mines. The purpose of this cooperation is to investigate resources, mining methods, and the application to industrial and domestic uses of coals of the central coal mining district. The gas and coking industry uses a large amount of coal, and many attempts have been made to increase the application of coals of the central district to the industry in this region. The use of central district coals for gas making presents many problems, of which the purification of the gas from hydrogen sulphide derived from the coal is an important one. The present overloaded condition of the gas-purifying equipment in many gas plants, brought about by economic conditions during the past few years, has increased the interest attaching to gas purification. Purifying conditions in several plants have become critical on account of the greatly increased gas production and the generally higher sulphur content of the fuels used for gas making. The financial condition of many gas companies practically prohibits the installation of larger equipment. The only solution of the problem for the present, therefore, lies in the more efficient use of existing equipment. That there is much room for improvement in this department of gas manufacture was shown in Bulletin 25 of the Cooperative Mining Series, published by the Illinois State Geological Survey. In that bulletin the purifying conditions in the medium-size gas plants of Illinois were discussed and certain improvements in operating methods were suggested, but it was pointed out that more information was needed relative to the properties of various types of oxide of iron, which have
