The Production of Hydrogen Gas: Steam Methane Reforming

Steam Methane Reforming is the most widely used process for bulk gas production, accounting for 95% of the hydrogen produced in the United States. The Steam Methane Reforming process can be broken down into five distinct steps: 1. Water enters the furnace, producing steam at a very high temperature. 2. Steam reacts with natural gas, producing hydrogen and carbon monoxide. 3. In the water shift ...

steam methane reforming 1. Introduction Hydrogen is mostly produced today through steam reforming of natural gas [1,2]. The main reaction is assumed to be represented by steam methane reforming (SMR), an endothermic equilibrium reaction: CH4 + H2O ˝ CO + 3 H2 DH298 = +206.63 kJ/mol (1) Establishing together with the water gas shift (WGS) equilibrium: CO + H2O ˝ CO2 + H2 DH298 = 41.16 kJ/mol ...

Steam reforming.The dominate steam-reforming processes convert natural gas, LPG or naphtha, with water vapor in the presence of a nickel catalyst, into a hydrogen-rich synthesis gas. The process reaction is: C nH m + H 2O→ H 2 + CO + CO 2 + CH 4 +H 2O at a temperature of 800°C–900°C and a typical pressure of 10–25 bar. The classic steam-reforming process with external heat supply (Figs ...

Steam Methane Reforming: steam methane reforming refers to the entire process in Figure 1. This name is commonly retained even when other feedstocks (e.g. naphtha) are used. Meanwhile, the steam methane reformer refers only to the fired chemical reactor in which Reaction 1-3 takes place. 4. Hydrogen Production by Steam Methane Reformers
