Abstract: [eng] [cze]
Tar content in gas produced by the gasification of biomass always plays an important role because high tar content disables some potentialities of the further treatment of the produced gas. There is a strong effort to produce gas with low tar content from this point of view. High concentrations of hydrogen and carbon monoxide also advance possibilities of the usage of the produced gas. Experiments were carried out in a reactor for plasma gasification equipped with hybrid gas-water stabilized DC torch. They confirmed that the reactor is absolutely suitable for this purpose mainly due to extremely low flow of plasma composed of argon, hydrogen and oxygen and its high inner temperature. The measurements of the tar content, using wood as a treated material, were based on SPE method and the determination of benzene and toluene in a gas phase revealed really low concentrations of tar, mostly below 10 mg/Nm3. Obsah dehtů obsažených v plynu vzniklém při plazmovém zplyňování je velmi podstatný zejména z hlediska dalšího využití tohoto plynu. Čím větší obsah vodíku a oxidu uhelnatého a nižší obsah dehtů, tím lépe. Při zplyňování dřevěných pilin v reaktoru vybaveném hybridním vodou stabilizovaným plazmatronem bylo dosaženo extrémně nízkých hodnot dehtů v produkovaném plynu.
