  • In steam-methane reforming, methane reacts with steam under 3ā€“25 bar pressure (1 bar = 14.5 psi) in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide. Steam reforming is endothermicā€”that is, heat must be supplied to the process for the reaction to proceed.
  • Steam Methane Reforming (SMR) is a chemical process used in the gas manufacturing industry to produce hydrogen on a large scale. This process contains two chemical reactions which ultimately convert water and methane (usually in the form of natural gas) into pure hydrogen and carbon dioxide. The hydrogen gas is then further purified to a quality specified by the customer. SMR is the most common and economical way to make hydrogen gas, which is used for electricity production, refining oil,...

Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is hydrogen production .

The steam reforming of methane consists of three reversible reactions: the strongly endothermic reforming reactions (1) and (3), and the moderately exothermic water-gas shift reaction (2): CH

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 reactor, carbon monoxide and steam react to form carbon dioxide and more hydrogen gas. 4.

progressive understanding of reforming of complex hydrocarbons. Methane steam reforming (MSR), CH4 + 2H2O = CO2 + 4H2 is, in fact, the most common method of producing commercial bulk hydrogen along with the hydrogen used in ammonia plants. United States alone produces 9 million tons of hydrogen per year. The overall MSR

Methane steam reforming involves two reversible reactions: the reforming reaction 1 and the Water-Gas-Shift reaction 2. The third one 3 is the global reaction. Reactions I and III are endothermic, but the water gas shift reaction is exothermic. The reaction scheme studied is as follows [15], [19], [21], [32-35]: 3 , 0 206 / (reaction 1)

investigations of the kinetics of methane steam reforming since the early 1950s [2,4ā€“6,8ā€“10,12,19,25,27]. Methane steam reforming is a quite complex process. It not only involves the transfer and diffusion of reactants and prod-ucts between the bulk phase and catalyst surface as well as within the catalyst, but also involves several reactions simul-

In steam-methane reforming, methane reacts with steam under 3ā€“25 bar pressure (1 bar = 14.5 psi) in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide. Steam reforming is endothermicā€”that is, heat must be supplied to the process for the reaction to proceed.

Steam-methane reforming is a catalytic process that involves a reaction between natural gas or other low-boiling hydrocarbon derivatives and steam. Steam-methane reforming is the benchmark process that has been employed over a period of several decades for hydrogen production.

The steam forming step, where methane reacts with water to produce carbon monoxide and hydrogen, is an endothermic process. Thus, the process is usually maintained at approximately 850Ā°C to obtain desirable conversion. [4] The second step is known as the water-gas shift reaction where syngas reacts to recover hydrogen.
