Web7 apr. 2024 · At the 2024 4C Health, Safety & Environmental Conference, Emerson’s Lara Rabbath presented Decarbonization with Steam Methane Reforming for Blue Hydrogen Production. Here is her presentation abstract: The primary method for blue hydrogen production is mainly from natural gas (methane), using steam methane reforming … WebThe deactivation pattern of a “model” Ni/MgO catalyst in the pre-reforming of n-hexane with steam (T, 450 °C; P, 5–15 bar) is reviewed. The influence of the steam-to-carbon ratio (S/C, 1.5–3.5) on the rate of catalyst fouling by coking is ascertained. Catalyst fouling leads to an exponential decay in activity, denoting 1st-order dependence of the coking process on …
