Method and system for producing integrated hydrogen from organic matter

摘要

A method for production of hydrogen from organic matter, includes: pyrolysis of a feed of organic matter by passing a gaseous treatment stream essentially having carbon dioxide through the organic matter, the pyrolysis producing, on the one hand, a pyrolysis gas stream having the gaseous treatment stream, steam and volatile organic compounds originating from the organic matter, and on the other hand pyrolysis chars having carbon components; oxycombustion of at least a proportion of the volatile organic compounds present in the pyrolysis gas stream, by injection of oxygen, upstream of a layer of redox filtering matter comprising high-temperature carbon components; and after the oxycombustion, passing the oxidized pyrolysis gas stream through the redox layer, the passage producing a synthesis gas stream comprising hydrogen obtained by deoxidation of steam by the high-temperature carbon components.

1. A method for production of hydrogen from organic matter, said method comprising the following stages:
pyrolysis of a feed of organic matter by passing a gaseous treatment stream comprising carbon dioxide through said organic matter, said pyrolysis producing, on the one hand, a pyrolysis gas stream comprising the gaseous treatment stream, steam and volatile organic compounds originating from said organic matter, and on the other hand pyrolysis chars comprising carbon components; oxycombustion of at least a proportion of said volatile organic compounds present in said pyrolysis gas stream, by injection of oxygen, upstream of a layer of redox filtering matter comprising high-temperature carbon components; and after said oxycombustion, passing said oxidized pyrolysis gas stream through said redox layer, said passage producing a synthesis gas stream comprising hydrogen obtained by deoxidation of steam by the high-temperature carbon components.
