The work presented here is the follow-up of the research carried out on a patented pilot plant called COIL for H2S removal from biogas. The goal of the research is to improve the overall efficiency of the clean-up process, limiting the elemental sulphur encrustations. Furthermore, a biotrickling filter prototype called BLUAY has been used to check the generation of H2 by bacteria is nitrogenase. So trials have been conducted with a different species of green-sulphur phylum Chlorobia, the salty water specie C. phaeovibrioides and the fresh water one C. limicola. Furthermore, consortia of these species with Desulphuromonas acetoxidans have been characterized as well. Modifications led to improvement of coil plant up to 135%.

Abstract

The work presented here is the follow-up of the research carried out on a patented pilot plant called COIL for H2S removal from biogas. The goal of the research is to improve the overall efficiency of the clean-up process, limiting the elemental sulphur encrustations. Furthermore, a biotrickling filter prototype called BLUAY has been used to check the generation of H2 by bacteria is nitrogenase. So trials have been conducted with a different species of green-sulphur phylum Chlorobia, the salty water specie C. phaeovibrioides and the fresh water one C. limicola. Furthermore, consortia of these species with Desulphuromonas acetoxidans have been characterized as well. Modifications led to improvement of coil plant up to 135%.
