Effects of CaCO3 and CaO Loading on Pore Structure, Multifractal Evolution, and Product Transformation During CO2 Gasification of Low-Rank Coal
Underground coal gasification (UCG) is an important in situ conversion technology for the clean and efficient recovery of deep and difficult-to-mine coal resources. Reactions between high-temperature char and gasifying agents such as CO2 and H2O in the reduction zone directly control the generation of valuable gases, p...
