China's coke industry: Recent policies, technology shift, and implication for energy and the environment
چکیده انگلیسی

China is the largest coke producer in the world, accounting for over 60% of the world coke production, which makes the coke industry in China a significant coal consumer and air pollutant emitter. Recently, China has taken a series of measures to improve energy efficiency and reduce emissions from the coke industry, including eliminating old and low energy-efficiency coking technologies, promoting advanced technologies, and strengthening energy and environmental requirements on coking processes. As a consequence, China's coke industry is experiencing an unprecedented technology shift, which was characterized by the elimination of old, inefficient, and polluting indigenous ovens and small machinery ones within 10 years. This study examines the policies and the prompt technology shift in China's coke industry, as well as the associated energy and environmental effects, and discusses the implications with respect to the development of the coke industry in China towards a more efficient and clean future. As China sets stricter requirements on energy efficiency and the ambient environment, a more significant change focusing on technologies of energy saving and emission reduction is urgently needed at present. Those mature technologies, including coke dry quenching, coke oven gas recycle, fine particle removal, etc., should be enforced in the near future.


► With 60% of world coke output, China's coke making has big energy/pollution issues.
► Actions were taken to improve energy and environmental performance of coke plants.
► China's coke industry is experiencing an unprecedented technology shift.
► Another shift, focusing on technologies of energy and emission saving, is needed.
► More measurement studies on coking emissions are needed given the importance.
