METHOD AND DEVICE FOR UTILIZING STRAW-LIKE BIOMASS IN FIXED BED GASIFICATION PROCESS

An invention relates to a method for utilizing bi¬o¬mass, wherein following steps are performed: first, at least one raw material containing carbon is ther¬ma¬lly gasified. In a next step, the synthesis gas produced in the gasification is purified. During said purifica¬ti¬on, the temperature of synt...

Beschreibung
Zusammenfassung:	An invention relates to a method for utilizing bi¬o¬mass, wherein following steps are performed: first, at least one raw material containing carbon is ther¬ma¬lly gasified. In a next step, the synthesis gas produced in the gasification is purified. During said purifica¬ti¬on, the temperature of synthesis gas is changed. Then the synthesis gas is preferably con¬ver¬ted into liquid fuel by means of catalyzed chemical reaction, whe¬rein straw-like biomass is selec¬ted as the raw material containing carbon, the gasification is performed in fixed bed reactor, and ash-softening temperature of straw-like raw material is increased by adding at least one alkaline-earth salt.
