Abstract
The present invention concerns a method for preparing a CO-rich gas stream for injection purposes or deposition, and a hydrogen rich gas stream, the method comprising the following steps: a) natural gas and HO are fed into a one-step reforming process for preparing a gas mixture comprising COand Hunder 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 H-rich and CO-rich gas stream, respectively. The invention also comprises use of CO-rich gas stream for injection into marine formations, and use of H-rich stream for hydrogenation, as a source of energy/fuel in fuel cells and for production or electricity.
