Hydrogen Production with Steam Methane Reforming and CCUS

WebSteam reforming or steam methane reforming (SMR) is the reaction where steam and hydrocarbons, such as natural gas or refinery feed stock, react in a reformer at temperature of 800˚C - 900˚C and moderate pressure (around 30 bar) in the presence of metal based catalyst for the production of syngas [5] . Syngas reacts further to give more ... WebThe water−gas shift reaction, where CO and H 2 O react to form CO 2 and H 2, is an exothermic reaction that connects SMR and DMR, and it affects the H 2 /CO ratio that can be thermodynamically obtained in the presence of H 2 O and CO 2 (see Figure S2). This phenomenon is leveraged on industrial scale to tune the final gas composition.

WebIn an SMR based plant, a heated mixture of the hydrocarbon feedstock and steam flows through catalyst filled tubes within a fired furnace called a reformer. In the presence of nickel catalyst, the mixed feed reacts with steam to produce hydrogen and carbon oxides by the following reactions: CnHm + nH2O → nCO + (m/2+n) H2. Web21 Oct 2024 · The SMR reaction is CH4 + H2O (+ heat) = CO + 3H2. In the DRI production process, NG is reformed in a reformer which is a gas tight refractory lined furnace containing alloy steel tubes filled with a catalyst. The feed gas to the reformer is the fresh NG blended with the top gas from the shaft furnace which is being recycled.
