Abstract:
The invention relates to a method for converting energy while using biomass in an open circuit, during which a controllable quantity of biomass, while supplying an exhaust gas of an internal combustion engine (12) containing carbon dioxide and water vapor, is gasified and reduced to form a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is cooled while precipitating a condensate (37) and forming a residual gas. This residual gas is separated in a controllable manner into a first and a second portion. The first portion of the residual gas is subjected to a shift reaction and is subsequently led through a molecular sieve (44) while separating out hydrogen gas, and the hydrogen gas resulting therefrom is combined with the second portion of the residual gas for the synthesis of hydrocarbon compounds that are suitable for use as fuel, and a portion of gas not converted during the synthesis is fed either to the internal combustion engine (12) in the form of fuel or to another unit in the form of a heating medium. The invention also comprises a corresponding circulation system and an internal combustion engine.
Abstract:
The invention relates to a device for extracting fuels from biomass while adding electrical energy, comprising the following components: a gasifier (33) for gasifying the biomass while adding electrical energy to a gas mixture, a reformer (35) for reforming the gas mixture obtained from the gasification, a gas scrubber (38) for scrubbing the reformed gas mixture, the device (300) further comprising a heating system upstream of and/or in the region of the reformer for additionally heating the gas mixture obtained from the gasification and a first recirculation device (351) so that the reformed or scrubbed gas mixture can optionally be recirculated to the gasifier (33) or supplied to at least one correspondingly downstream component of the device, the first recirculation device (351) providing a recirculation loop for the reformed or scrubbed gas mixture and the recirculation loop comprising at least the gasifier (33) and the reformer (35).
