Fremgangsmõte for õ fremstille en H2-rik gass og en CO2-rik gass ved høyt trykk

摘要

The present invention concerns a method for preparing a CO₂-rich gas stream for injection purposes or deposition, and a hydrogen rich gas stream, the method comprising the following steps: a) natural gas and H₂O are fed into a one-step reforming process for preparing a gas mixture comprising CO₂ and H₂ under supercritical condition for water from about 400° C. to about 600° C. and pressure from about 200 to about 500 bar in the reforming reactor; b) the gas mixture from a) is separated into a H₂-rich and CO₂-rich gas stream, respectively. The invention also comprises use of CO₂-rich gas stream for injection into marine formations, and use of H₂-rich stream for hydrogenation, as a source of energy/fuel in fuel cells and for production or electricity.
