- the CO 2 produced by the combustion and the reactions of the source solid fuel is preferably, according to the invention, of vegetable origin (it is neutral with regard to the issue of greenhouse gases since the plant to renew absorbs its CO 2 equivalent to regrowth). Its liquefaction (for industrial use), its sequestration, its transformation into CO (as a substitute for fossil fuels) makes it possible to reduce the proportion of industrial CO 2 from fossil sources released to the atmosphere. Its recycling by the system according to the invention maximizes the conversion efficiency, the "source” energy of the initial solid fuel, energy made available by synthetic hydrocarbon compounds.
- the enclosure E is made to meet the temperature standards of the reactors 10 and 20.
