抄録

The previous paper described the first experiment in laboratory on the underground gasification of coal by using only air. This paper describes the gasification of coal by using oxygen. The purpose of this experiment was to know the outline of gasification processes which took place by using oxygen. The author concludes as follows;<BR>1. By using oxygen, the calorific value of gas is greater than that by using air only.<BR>2. The gasified zone is also greater. In our experimental apparatus-the amount of oxygen is 3. 2l/min, length of borehole 30cm and diameter of this hole 1. 2mm-we could get the gas, of which calorific value is more than 1000 kcal/Nm3, during about 10 hours.<BR>3. By using oxygen, we can get the desirable gas. But what amount of gas is much desirable in this case? What reduction process occurs in coal seam?<BR>Can we get the reaction speed in gasification process of coal? Many experiments about these themes were carried out in our laboratory, and that will be described in next paper.
