TLDR
In this paper, the authors comprehensively review the recent advances for chemical-looping reforming of CH4 (CLR) technology, which breaks down the traditional CH4 reforming process (including steam and dry reforming) into two separate half-steps, namely CH4 oxidation and replenishment of oxygen carrier (OC) with appropriate oxidizing agents.About:

Pulverized Sponge Iron, a Zero-Carbon and Clean Substitute for Fossil Coal in Energy Applications
Henrik Wiinikka,Henrik Wiinikka,Therese Vikström,Jonas Wennebro,Pal Toth,Pal Toth,Alexey Sepman +6 more
TL;DR: In this article, the authors show that the emission of CO2 is insignificant during the combustion of pulverized sponge iron compared to that of coal combustion, and that the emissions of other harmful pollutants NOx and SO2 were 25 and over 30 times lower, respectively, than in the case of pulpined coal combustion.
