Abstract
A method of producing hydrogen in a plant for hydrogen production during combustion of a mixture of hydrocarbon feedstock with an oxidizer with an oxidant excess ratio of less than 1. The method is characterized in that the combustion process is carried out at a temperature of less than 1400 K inside several cavities, completely or partially formed by a material permeable to a mixture of hydrocarbon feedstock with an oxidant.
Claims19
A method for producing hydrogen (H2) from hydrocarbon material, comprising:
- mixing of the hydrocarbon material with an oxidant to form a mixture of the hydrocarbon material and the oxidant;
- flowing of the mixture through a porous material, wherein the porous material has, and is bounded by:
- an inflow surface through which the mixture enters the porous material from an upstream space located behind the inflow surface, and
- an opposite outflow surface through which any combustion products of the mixture and any non-combusted portions of the mixture exit the porous material to enter a downstream space located in front of the outflow surface;
- and
- combustion of the mixture only in a combustion zone, wherein the combustion zone is only within the porous material and/or in front of and adjoining the outflow surface, to produce syngas that includes combustion products of the mixture and any non-combusted portions of the mixture;
- wherein heat generated by the combustion in the combustion zone raises the temperature of the combustion zone to a combustion temperature, which is a temperature sufficiently high to trigger the combustion of the mixture, and
- the temperature in the upstream space behind the inflow surface remains below the combustion temperature so that combustion does not occur behind the inflow surface to any significant extent.

An apparatus for producing hydrogen (H2) from hydrocarbon material, comprising:
- an inner porous material that surrounds and bounds an inner cavity;
- an intermediate cavity that surrounds and bounds the inner porous material;
- an outer porous material that surrounds and bounds the intermediate cavity;
- an outer cavity that surrounds and bounds the outer porous material;
- an outer wall that surrounds and bounds the outer cavity;
- an inner chamber wall that encases the inner cavity, is formed at least in part by the inner porous material, and has an outlet;
- an intermediate chamber wall that encases the intermediate cavity and is formed at least in part by the outer porous material;
- an outer chamber wall that encases the outer cavity and has an outlet;
- a mixture-supply device configured to supply a mixture of a hydrocarbon material and an oxidant to the intermediate cavity;
- the apparatus being configured to function such that:
- a first portion of the mixture flows radially-inward from the intermediate cavity into the inner porous material, to combust in a first combustion zone located in the inner porous material and/or in the inner cavity, to fill the inner cavity with first syngas comprising combustion products of the first mixture portion and any non-combusted portion of the first mixture portion;
- the first syngas exits the inner cavity through the inner chamber's outlet;
- a second portion of the mixture flows radially-outward from the intermediate cavity into the outer porous material, to combust within a second combustion zone located in the outer porous material and/or in the outer cavity, to fill the outer cavity with second syngas which comprises combustion products of the second mixture portion and any non-combusted portion of the second mixture portion;
- the second syngas exits the outer cavity through the outer-chamber's outlet;
- heat generated by the combustion of the first and second mixture portions raises the temperature of the combustion zone to a combustion temperature, which is a temperature sufficiently high to trigger the combustion, while the temperature throughout the intermediate cavity remains below the combustion temperature so that combustion does not occur in the intermediate cavity.
