Development and Problems of Fluidized Bed Ironmaking Process: An Overview

Interactions of graphene with oxidants in a mixed atmosphere: synergistic effects of O2/H2O and O2/CO2 on gasification reactivity and kinetics

“…Controlling the kinetics of carbon gasification with O 2 , CO 2 , and H 2 O oxidants is a key technical challenge in applications such as the oxyfuel combustion (OFC) system, 1,2 integrated gasification combined cycle (IGCC), 3 underground coal gasification (UCG), 4,5 net-zero emissions steel production system, 6,7 etc. In the context of future low-carbon scenarios, these processes play a pivotal role in the transformation of coal utilization resources.…”

Phase Evolution Behavior during the Reduction Process of Medium‐Silica Fluxed Pellets

“…In recent years, due to their energy-saving advantages, emission reduction, and environmentally friendly low-carbon properties, pellets have gradually become the raw material for smelting in blast furnaces. [1][2][3] Depending on the SiO 2 content of the gangue phase in the magnetite ore concentrate, magnetite is classified as low silica when the SiO 2 content is less than 3%, medium silica when the SiO 2 content is between 3% and 6%, and high silica when the SiO 2 content is more than 6%. [3][4][5][6] Magnetite fines used for pellets in China typically have a higher silica content, often exceeding 6%.…”

[3][4][5][6] Magnetite fines used for pellets in China typically have a higher silica content, often exceeding 6%. The research and development of fluxed pellets for medium-and high-silica magnetite is essential to enhance the utilization of pellets in blast furnaces for many domestic pellet enterprises.…”
