Producing an energy carrier made of straw or wood by torrefaction in a reactor having a torrefaction zone and a compression zone, comprises connecting torrefaction zone and compression zone to each other

The process of producing an energy carrier (2) made of straw or wood by torrefaction in a reactor (1) having a torrefaction zone and a compression zone integrated into the reactor, comprises connecting the torrefaction zone and the compression zone to each other. The torrefaction zone and the compression zone stand with each other in a transition region in a gas exchange. The biomass is guided into the reactor, and is thermochemically converted into the torrefaction zone. The torrefaction biomass in a hot state is compressed into the compression zone. The process of producing an energy carrier (2) made of straw or wood by torrefaction in a reactor (1) having a torrefaction zone and a compression zone integrated into the reactor, comprises connecting the torrefaction zone and the compression zone to each other. The torrefaction zone and the compression zone stand with each other in a transition region in a gas exchange. The biomass is guided into the reactor, and is thermochemically converted into the torrefaction zone. The torrefaction biomass in a hot state is compressed into the compression zone. An outlet opening of the reactor is closed in a gas-tight manner for the torrefaction biomass, where a closure is formed by the torrefaction biomass. The torrefaction zone is supplied to a flue gas from biogas combustion. The torrefaction biomass is crushed before the subsequent compression. An independent claim is included for a reactor for producing an energy carrier made of straw or wood by torrefaction in a reactor.
