Work Of The Illinois Technical Committee On Gas, By-Products, And Public Utilities

The serious shortage of eastern gas coal and of coke for gas-making in Illinois and adjoining states during the winter of 1917-1918 was emphasized at the meeting of the Illinois Gas Association, March, 1918. The seriousness of the situation was of concern not merely to private interests but to the general public, which consumes gas for heating, lighting, and for important industrial uses. Some relief was thought possible if central district coals from Illinois, Indiana, and western Kentucky could be used generally as a substitute for eastern coal and coke in the manufacture of retort gas and water-gas. Already a little Illinois and Indiana coal was being used under special circumstances in Illinois retort plants and successful experiments with mixtures of Illinois coal and eastern coal had been conducted at the Decatur retort-gas plant by F. K. Ovitz of the U. S. Bureau of Mines and the Illinois Mining Investigations, with the advice and cooperation of a committee of the Illinois Gas Association. Consequently, it seemed desirable to continue experiments with central district coal in gas retorts, and with coal as a substitute for coke in water-gas generators, and to give publicity to the results and technical assistance to companies desiring to use central district coal. Other matters, of national importance were the prospective shortage of toluol and of ammonia for the manufacture of explosives, and the possibility of encouraging recovery of additional amounts from some of the plants in central states that were not contributing these substances. Results of work done by the Gas Section, Illinois Mining Investigations, under the advice of the Technical Committee, were pushed to early publication until the signing of the armistice lessened the importance of speed as a war measure. The first two publications listed below were distributed by the Regional Director of the U. S. Fuel Administration, through the Bureau of Gas. By-products and Public Utilities. The others were distributed by the Geological Survey. Bulletin 21. The Manufacture of Retort Coal-gas in the Central States Using Low-sulphur Coal, from Illinois, Indiana, and, Western Kentucky. Bulletin 22. Water-gas Manufacture with Central District Bituminous Coals as Generator Fuel
