Abstract

“Underground Gasification of Coal”is a process for bringing to the surface as gcs the useful ingredients of coal, while leaving the unwanted material behind in the seam.<BR>In laboratory the author conducted many basic experiments in underground gasification of coal. In this report, a first experiment is described.<BR>The author tried to gasify a small coal block, which was made artificially, by using only air. This preliminary experiment showed the following conclusions:<BR>1. It is difficult to get the desirable gas. The amount of gas produced, and amount of coal gasified are small.<BR>2. The volumetric amount of hydrogen and CmHn, in gas produced are very small, and also calorific value of it very small. It is clear that, a lot of heat lost occurrs in the process of underground gasification of coal.<BR>3. it is necessary to use oxygen for getting a lot of gas of the high calorific value. The author will describe in next repors on the basic study of gasification of coal by using oxygen.
