Abstract
Methods and pyrolysis plants are described, comprising reactors for producing pyrolysis gas from biomass. The reactors comprise one or more reaction channels linked thermally with at least one heating circuit, which is configured to heat the reaction channels to a temperature that is high enough to gasify the biomass. The reactors comprise a feed section configured for feeding the biomass into the reaction channels. The pyrolysis plants comprise a gas accelerator configured for recirculating the gas that is present in the at least one reaction channel and for providing a gas flow velocity that is able to distribute the biomass in the reaction channel.

A pyrolysis plant comprising:
- a reactor for producing pyrolysis gas from biomass, the reactor comprising:
- one or more reaction channels linked thermally with at least one heating circuit configured to heat the one or more reaction channels to a temperature that gasifies the biomass;
- and
- a feed section configured for feeding the biomass into the one or more reaction channels;
