Abstract:

The coal blend and coke-making experiment was conducted on 5 kg test oven to study the influence of additive amount and grain size of waste activated carbon, the result showed that it was feasible that in coal blending and coke-making lean coal was replaced by a certain amount of waste activated carbon, when the blending amount and grain size of waste activated carbon were respectively controlled at 0.5%~2% and 0.5~1.0mm, there was no influence on cold strength and hot strength of coke. To replace lean coal for coke-making with waste activated carbon can reduce the cost of coal blend, and the issues of wasting resource and environmental pollution can be effectively solved.
