No.30 Differences of Oxidation Properties between Coal and its Hyper-coal

Abstract

Air oxidation properties of coals and its Hyper-coal's (ash-free coal, HPC) were studied to utilize the HPC as a feedstock for carbonaceous materials with high purity. It was revealed that differences of oxidation properties between HPC's and the coals were attributed to those aliphatic carbons and micropore distribution. Oxidation reactivity of HPC at high temperature was lower than that of the coal due to the low surface area.
