Advances in biomass gasification in terms of new feedstocks and tar reforming.
Comparison o f Two Fine Gas Cleaning Systems for Product Gas: Catalyst Poison Removal Efficiencies of Multi-Step Gas Cleaning and Temperature Swing Adsorption
Short Introductive summary
The dual fluidized bed steam gasification process delivers a high-quality product gas, H2, CO, CO2, CH4 and impurities such as fly char, tars, as well as S-, Cl- and N-components. In a 1 MW demonstration plant located at the “Syngas Platform Vienna” a wide variety of feedstocks are tested for their gasification properties. In order to utilize the product gas in downstream catalytic processes, such as FT-synthesis, SNG-synthesis or renewable H2 production, gas cleaning steps need to be applied. In the demonstration plant, the so-called coarse gas cleaning is established. Downstream catalytic processes increase the demand on gas quality. Therefore, further gas cleaning steps were investigated in two different fine gas cleaning chains. In the traditional set-up, several different cleaning stages need to be combined, while the second set-up attempts to achieve the cleaning effect by means of temperature swing adsorption(TSA). First results of the novel TSA plant show a promising decrease in BTX- and sulphur components via the activated carbon. The results will be further compared to the impurities over the traditional fine gas cleaning set-up using wood chips as feedstock.
