Hydrogen Separation for Hydrocarbon Reforming Gas

摘要

A process involves separating hydrogen that is produced from a reformer. Specifically, the products, which include hydrogen, CO2 and hydrocarbons, are added to a CaO bed. The CaO reacts with the CO2 to form CaCO3, thereby removing CO2 from the products. The remaining products (e.g., hydrocarbons and hydrogen) may be separated using a hydrogen-sensitive membrane. This membrane will produce a refined, purified supply of hydrogen gas.

主权项

1. A method of separating hydrogen gas from other products produced by a reformer comprising:
adding the products to a CaO bed, wherein the CaO bed removes CO2 from the products and forms a stream of hydrocarbons and hydrogen; processing the stream of hydrocarbons and hydrogen with a membrane, wherein the membrane separates out the hydrogen.
