- Abstract
The article discusses experimentation on the removal of hydrogen sulfide from biogas by chemical contact of biogas and a catalytic solution of iron and ethylenediaminetetraacetic acid (Fe-EDTA). Experimental apparatus allowed for bubbling of biogas through the Fe-EDTA solution. A wide range of biogas and Fe-EDTA flow rates were tested to identify an optimal operating ratio. When regenerated Fe-EDTA solution was recirculated, the sulfur particles generated in the initial chemical reaction grew in size, suggesting their ease of removal from solution.
