Web6 apr. 2024 · The primary natural sink for methane is the atmosphere itself, as methane reacts readily with the hydroxyl radical (OH −) within the troposphere to form CO 2 and water vapour (H 2 O). When CH 4 reaches the stratosphere, it is destroyed. Another natural sink is soil, where methane is oxidized by bacteria. Web12 apr. 2024 · Dry reforming of methane(DRM) is an important reaction to utilize two greenhouse gases(CO2 and CH4) simultaneously and produce syngas(CO and H2) for the manufacture of downstream high-value chemicals. One of the major obstacles to preventing the commercialization of Ni-based catalysts in DRM is the serious coking problem.
