Abstract
A method and apparatus for gasifying raw material. The method includes feeding the raw material into an upper part of a fixed-bed gasifier, introducing the raw material from the upper part of the gasifier to a pyrolysis zone of the gasifier to form the fixed-bed and pyrolyzing the raw material in the presence of pyrolysis air to form a pyrolysis product. Introducing the pyrolysis product from the pyrolysis zone to a lower part of the gasifier, introducing primary air countercurrently to the lower part, carrying out a final gasification in a lower part of the gasifier in order to form a gasified gas. Introducing the gasified gas to a catalytic oxidation part and through a catalyst layer of the catalytic oxidation part, and reforming the gasified gas by way of the catalytic oxidation in the presence of reforming air in the catalytic oxidation part, forming a gaseous product.
