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.

Steam methane reforming process for hydrogen production?

  • 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,...
