Abstract

Hydrogen sulfide (H2S) is a hazardous chemical compound present in raw biogas and requires removal. Biofiltration offers an eco-friendly solution by utilizing sulfur oxidizing bacteria (SOBs) within a biofilter. This biofilter typically comprises packing material to house SOBs and facilitate desulfurization. To optimize removal efficiency (RE), the physicochemical properties of packing materials (organic/inorganic/synthetic) need evaluation. This study focused on the characteristics of sewage sludge and biochar samples produced via pyrolysis at temperatures of 400 °C, 500 °C, and 600 °C, along with cellular concrete (CLC) waste and polyurethane foam (PUF). Measurements included bulk density, pH, and electrical conductivity, with discussion on their impact on H2S purification from biogas under dynamic conditions. Ultimately, PUF, CLC waste, biochar after 600 °C pyrolysis, and sewage sludge exhibited superior performance in terms of lowest bulk density, optimal pH, and highest electrical conductivity.
