The adsorbent investigated was powdered hematite, synthesized by a wet-chemical precipitation method and further activated with copper (II) oxide, used both as produced and after pelletization with polyvinyl alcohol as a binder. The pelletization procedure aims at optimizing the mechanical properties of the pellet without reducing the specific surface area. The active substrate has been characterized in its chemical composition and physical properties by X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), thermogravimetric analysis (TGA) and N2 physisorption\/desorption for the determination of surface area. Both powders and pellets have been tested as sorbents for biogas purification in a fixed bed of a steady-state adsorption column and the relevant breakthrough curves were determined for different operating conditions. The performance was critically analyzed and compared with that typical of other commercial sorbents based on zinc oxide or relying upon specific compounds supported on a chemically inert matrix (SulfaTreat\u00ae). The technique proposed may represent a cost-effective and sustainable alternative to commercial sorbents in conventional desulphurization processes.<\/jats:p>","DOI":"10.3390\/ma13214725","type":"journal-article","created":{"date-parts":[[2020,10,22]],"date-time":"2020-10-22T20:51:00Z","timestamp":1603399860000},"page":"4725","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Hydrogen Sulfide Adsorption by Iron Oxides and Their Polymer Composites: A Case-Study Application to Biogas Purification"],"prefix":"10.3390","volume":"13","author":[{"given":"Camilla","family":"Costa","sequence":"first","affiliation":[{"name":"DCCI, Department of Chemistry and Industrial Chemistry, Universit\u00e0 degli Studi di Genova, Via Dodecaneso 31, 16146 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo","family":"Cornacchia","sequence":"additional","affiliation":[{"name":"DCCI, Department of Chemistry and Industrial Chemistry, Universit\u00e0 degli Studi di Genova, Via Dodecaneso 31, 16146 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcello","family":"Pagliero","sequence":"additional","affiliation":[{"name":"DCCI, Department of Chemistry and Industrial Chemistry, Universit\u00e0 degli Studi di Genova, Via Dodecaneso 31, 16146 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5646-2568","authenticated-orcid":false,"given":"Bruno","family":"Fabiano","sequence":"additional","affiliation":[{"name":"DICCA, Department of Civil, Chemical and Environmental Engineering, Polytechnic School, Universit\u00e0 degli Studi di Genova, Via Opera Pia 15, 16145 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6824-4488","authenticated-orcid":false,"given":"Marco","family":"Vocciante","sequence":"additional","affiliation":[{"name":"DCCI, Department of Chemistry and Industrial Chemistry, Universit\u00e0 degli Studi di Genova, Via Dodecaneso 31, 16146 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea Pietro","family":"Reverberi","sequence":"additional","affiliation":[{"name":"DCCI, Department of Chemistry and Industrial Chemistry, Universit\u00e0 degli Studi di Genova, Via Dodecaneso 31, 16146 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"777","DOI":"10.1016\/j.matpr.2019.07.242","article-title":"Removal of hydrogen sulphide and odour from tannery & textile effluents","volume":"21","author":"Shivasankaran","year":"2020","journal-title":"Mater.
