An Experimental Approach for the Production of Pure Hydrogen Based on Wood Gasification

Popis výsledku v původním jazyce

In this experimental work, a unique process chain for hydrogen production based on biomass gasification has been investigated. For almost 100 hours, a pilot plant was operated continuously with 2 Nm?/h of dry product gas, derived from dual fluidized bedsteam gasification at the combined heat and power plant in Oberwart, Austria. The implemented process chain consisted of four operation units: (1) sulfur resistant catalysis of the water gas shift reaction, (2) gas drying and cleaning in a chilled rapeseed methyl ester scrubber, (3) hydrogen enrichment via membrane separation and (4) generation of pure hydrogen by means of pressure swing adsorption. High hydrogen yields of all operational units were achieved, resulting in an overall hydrogen recovery ofalmost 70% (42g/kg dry biomass). The purity of hydrogen was above 99.85%vol.
