No.2-20 褐炭改質によるコークス用粘結材（A-SCC）のコークス化性評価

抄録

We have been studying the cokemaking properties of A-SCC (Advanced Substitute Coking Coal) produced by thermal-hydrogenation processing of brown coal. After we refined the reforming conditions using a small autoclave, A-SCC derived from low ash brown coal was produced by auto-claves with capacity of 1.6L. The samples of A-SCC were analyzed to evaluate the performance as a coking additive. They were mixed with the test blend of coal consisting of 10% of poor coking coal and 90% of the standard blend of coal used for blast furnace coke production in Japan. The several samples of coke were produced with a simulated coke oven, a small-scale test facility. The strengths of coke were measured with several ratios of addition of A-SCC.
