WebApr 12, 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. This … WebSteam methane reforming (SMR) is a process in which methane from natural gas is heated, with steam, usually with a catalyst, to produce a mixture of carbon monoxide and hydrogenused in organic synthesis and as a fuel1. In energy, SMR is the most widely used process for the generation of hydrogen2.
WebHerein, a surface spatial confinement strategy was employed to design high-performing catalysts for the dry reforming of methane (DRM). Specifically, active nickel (Ni) nanoparticles (NPs) were confined on the surface of a dendritic mesoporous silica (DMS) in the form of the “catalysts in coronas”. The Ni/DMS catalyst exhibited a high ... WebThe importance to have a global vision on this topic is strictly related to the most currently and important challenges in the sustainable energy production. In fact, dry-reforming is one of the few known processes in which greenhouse gases are utilized as reactants (methane and carbon dioxide) to produce syngas.
WebMethane (US: / ˈ m ɛ θ eɪ n / MEH-thayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms).
