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.

### Specific heat of gas?

The specific heats of gases are generally expressed as molar specific heats. For a monoatomic ideal gas the internal energy is all in the form of kinetic energy, and kinetic theory provides the expression for that energy, related to the kinetic temperature. The expression for the internal energy is . Two specific heats are defined for gases, one for constant volume (C V) and one for constant pressure (C P).

### How does steam methane reforming work?

Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700°C–1,000°C) is used to produce hydrogen from a methane source, such as natural gas. In steam-methane reforming, methane reacts with steam under 3–25 bar pressure (1 bar = 14.

### Why gases have two specific heat?

Any form of matter will respond to heat, in different manners, at constant volume and constant pressure, hence have different specific heats. But solids do not have a huge variation since their interatomic distance remains the same at both constant volume and constant pressure, and so do liquids at certain temperature and pressure. That's why we use dual specific heat values for gases only.
