Influence of Cu(CH3COO)2 promoting additive on bituminous coal oxidation process

Research output: Contribution to journalConference article

Abstract

The process of coal oxidation with applied Cu(i H3COO)2 additive was studied by the capillary incipient wetness impregnation method with 5% mass concentration. The experiment was conducted by thermogravimetric analysis at a heating rate of 2.5°C/min to a maximum temperature of 600°C in atmospheric air. It was established that application of the initiation additive leads to a significant reduction in the initial temperature of sublimation and active oxidation of volatile compounds (ΔTi = 78°C) and the oxidation end temperature (ΔTf = 64°C). It was established that in the presence of copper acetate the nature of coal oxidation reaction significantly changes (DTG data). The parameters of the coals oxidation process in the presence of copper acetate were determined, and an assumption was made about the presence of a composite catalytic effect.
