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. 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.
WebApr 19, 2024 · Dry reforming methane (DRM) has been in the spotlight as this reaction has the advantage of solving two issues related to the reduction in greenhouse gas (GHG) emissions since it uses (CH 4 and CO 2) as feed stocks … WebThe dry reforming of methane is a process that requires the use of catalysts such as the noble metals Rh and Pt, supported on metal and nonmetal oxide support materials such as Al 2 O 3, MgO, TiO 2, ZrO 2, and CeO 2 ( Topalidis, et. al., 2007 ). Although these noble metals yield high activity and selectivity, they are relatively expensive.
