A WGS pilot plant was operated with tar-rich product gas from dual fluidized bed biomass steam gasification.
The WGS pilot plant was continuously operated for about 2250 h.
A commercial Fe/Cr based catalyst was employed.
No deactivation of the catalyst could be observed during the about 2250 h of operation.
The volumetric CO content in the product gas could be lowered from about 25% to below 2%.
