ABSTRACT
The Chinese coking industry (CCI) is currently facing a great challenge on reducing greenhouse gas (GHG) emissions. Our study was set up to assess the GHG emission characteristics of 10 representative coke enterprises and analyse the factors of fuel type, production scale, loading method, oven model, loading rate, etc. The research results showed that fuel gas type, oven model, and loading rate had obvious impacts on the carbon emission intensity of coking plants, while the production scale and the loading method had little effects. The carbon emission intensity of the coking plant using mixed fuel gas was much higher than the plant using coke oven gas as fuel. The carbon emission intensity of the 6.0 m coke oven was 0.7 times higher than that of the 4.3 m coke oven. And the emission intensity of the clean heat recovery coke oven was the highest. An infrequent low loading rate would increase the direct carbon emission intensity signifi cantly. The research results will help the government to compare the emission intensity of the coking industry and make policies about carbon emission intensity reduction.
