Web28 feb. 2024 · H 2, which is often produced by water electrolysis, is a common co-reactant in the conversion of CO 2 to CH 4, CH 3 OH, and other compounds. Electrolysis techniques are energy-intensive and expensive [ 68 ]. Near-zero emission energy sources must be employed for the systems to be carbon-neutral. WebCoal maceral composition has a great effect on gas adsorption and diffusion. The interaction between maceral composition and supercritical CO2 (SCCO2) fluid will affect gas diffusion behavior in coals. Thus, the diffusivity derived from adsorption kinetics of CH4 and CO2 in vitrinite- and inertinite-rich coals with low-violate bituminous rank collected from the …
