Abstract:
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.
Abstract:
A thermal method for stabilizing a load of wood, in particular timber, including: a phase of treatment of the load of wood in a treatment kiln by a gaseous treatment flow; generation of a gaseous treatment flow at high temperature from a heat generator independent of the treatment kiln and recovery of the loaded gaseous flow after treatment.
Abstract:
A method of generating energy from a gas flow, called the initial flow, including water vapour, the method including the deoxidation of at least some of the water vapour by passing the initial gas flow through a layer of material at high temperature, called the thermal base layer, essentially including high-temperature carbon, the deoxidation making it possible to obtain a first gas flow comprising hydrogen obtained by the reaction of the water vapour with the carbon elements. The initial flow may be a gas flow that has served for the treatment of a charge of wood. The hydrogen obtained constitutes an energy source and may then be used to produce energy by a gas boiler, a gas turbine, a fuel cell, a gas-powered engine, a turboalternator, or the like.
Abstract:
A method for roasting a load of plant biomass, includes the following stages: generation of a treatment gas stream by a thermal generating apparatus, the treatment gas stream being an inert gas consisting essentially of CO2; generation of a bed of material at high temperature, called the thermal base; treatment of the load of biomass with the treatment gas stream, the treatment gas stream being laden with gaseous components including a water steam and volatile organic compounds originating from the load of biomass during the treatment; and recycling of at least a portion of the water steam by passing at least a portion of the laden gas stream through the thermal base.
