Gasification of biofuels to a fuel gas with a high calorific value is taking place in at least two steps. One step is carried out in counter-current with the pre-pyrolysis for release of carbon dioxide. A second step with complete gasification is carried out in co-current. The gasifier, which can be called the counter-current/co-current gasifier, is supplied with a second counter-current section (3) for pre-pyrolysis with conduits (8 and 9) for supply and removal, respectively, of gas and a co-current section (5) for final gasification with a conduit (10) for gasification air and a conduit (11) for removal of fuel gas. |
