Consideration and Practice of Science, Technology and Strategy for Minimizing CO₂ Emission in Chinese Steel Industry

Abstract

In order to minimize CO₂ emission from iron and steel-making processes to abate greenhouse gas impact, the considerations and some practice of science and technology as well as its strategy completed and on going in Chinese steel industry are summarized. Two available ways for the minimizing in China so far:
(1)Minimizing carbon-consumption (fossil energy-saving) in all the processes of steel industry which is the most realizable measure for reducing CO₂ emission.
(2)To look for new alternative reaction medium in the processes where producing more CO₂ like H2 in blast furnace etc and new processes for iron and steel making which discharge less CO₂ .
Some new ideas like macro-based measures are put forward for minimizing CO₂ emission in steel industry.
