The permeance of hydrogen declined but methane permeance increased with an increase in gas pressure. The permeance of hydrogen declined sharply in the range of 1–2 bar and it steadily dropped especially for the pressure of 4–10 bar. The permeance of methane was enhanced steadily with a small slope in the range of 1–10 bar.

In a process called "methane cracking," the molecular components of methane – hydrogen and carbon – are separated at temperatures of over 750° C (1,382° F), without harmful emissions.

A process for separating hydrogen and methane from a gas mixture containing hydrocarbons heavier than methane in which the gas mixture is passed through a plurality of chilling stages, a bottoms...

A ceramic membrane makes it possible to produce compressed hydrogen from methane with near-zero energy loss.

Automatic equipment for separation of hydrogen from gas mixtures Gas mixture at 14 to 35 bar was fed into the chamber and the palladium allowed to absorb hydrogen for 1 to 8 seconds while hydrogen-depleted mixture was bled away at a rate predetermined by a downstream manual valve.

sort to separate hydrogen from nitrogen by absorbing hydrogen at low temperature and later expelling the gas by heating the metal. More recently Boice and Salmon (9) have described a method based on the same principle. Hydrogen was absorbed from the gas mixture by palladium at -78 to --IOOOC and was later recovered at 200 to 350°C. In

Temperature control is critical for maximum membrane separation. The membranes separate the desired gas constituents from the impurities in the gas stream which are rejected. Membranes can achieve purity up to 97%. For high purity Hydrogen (H 2) a pressure swing absorption (PSA) system is required after the membranes.

The results obtained in this investigation indicate that: (1) it is possible to obtain pure hydrogen from a mixture of hydrogen and natural gas using a PEM fuel cell as a separating device. (2) If the percent hydrogen recovery is less than 80% then only a small fraction of the energy available in the hydrogen is required to perform the separation.

Hydrogen from steam methane reforming with co2 capture energy?

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.

How is methane converted to hydrogen?

In steam-methane reforming, methane reacts with steam under 3–25 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 endothermic—that is, heat must be supplied to the process for the reaction to proceed.
