Emission Mitigation of CO2 in Steel Industry: Current Status and Future Scenarios

Coke oven gas: Availability, properties, purification, and utilization in China

“…An increase in the use of DRI processes has recently been observed due to less investment costs as compared to a BF technology [49,50]. Although DRI produces less amount of CO 2 as compared to BF technology, the amounts off-gas emissions are fairly high calling for a subsequent gas-recycling during the process [51]. CH 4 is mainly utilized as a reducing gas for DRI production and is popular among countries with rich natural gas reserves.…”

Synthesis of Ca-based Layered Double Hydroxide from Blast Furnace Slag and Its Catalytic Applications

“…The amount of CO 2 to produce every ton of steel is estimated to be about 2 200 kg of CO 2 on a world average (1 800 kg of CO 2 for many developed countries). 13,14) Therefore, chemical fixation of CO 2 into such industrially beneficial, valueadded compounds would provide interesting insights for sustainable development of iron and steel industry.…”

Combined steam and CO2 reforming of CH4 using coke oven gas on nickel-based catalyst: Effects of organic acids to nickel dispersion and activity

“…In addition, the byproduct gases generally contain CO 2 and CH 4 with abundant hydrogen form steel industries during a refining process of iron ores, which has been known to release a larger quantity of CO 2 in a single industry by occupying about 6% of the total released anthropogenic CO 2 [10,11]. The byproduct gases can be utilized for the CSCR reaction to produce H 2 -rich syngas or to synthesize syngas having various ratios of H 2 /CO through environmentally-benign recycling processes.…”
