The cokemaking industry Year＂, however it is still faced with the eokemaking in China developed rapidly during ＂Eleventh Fiveseverely unprecedented situation. Comparing with the technology used by developed countries, there exists a gap between China and developed countries in many respects such as fewer large-scale coke ovens in China, less measures to be taken for developing the technology with energy-saving and low emissions, structural overcapacity, relatively low concentration ratio of cokemaking industry which is the bottleneck for the cokemaking industry in China to be further developed. In order to become a powerful country in cokemaking technology from the No.1 country in producing cokes during ＂Twelfth Five-Year＂, large-scale top-charged coke ovens with low NOx emissions should be built and popularized and such technologies as large-scale stamp-charged cokemaking technology, coke .dry quenching technology, technology for recycling waste heat of flue gas from a coke oven and the efficient and en- ergy-saving desulfurization and decyanation technology should be developed and applied all over China. In addition, these new technologies such as the technology for recycling the waste heat of raw coke oven gas, the comprehensive utilization technology for coke oven gas and new treatment technology for cokemaking wastewater should be further developed. And it is proposed that large-scale units for processing coal tar and benzol hydro-refining should also be developed and built in China.
