- Removal of H2S using a natural clay modified with a surfactant and incorporating Cu, Fe and Zn into the structure Leiner Semprún Roger Solano Jorge Sánchez Gabriela Carruyo Miguel Ángel Ramos José Antonio Enao Reinaldo Atencio Tereza Bandosz Mykola Seredych Alexander Moronta Ingeniería H2S removal montmorillonite template method Mesoporous solids were used for hydrogen sulfide removal from stream H2S-Air. These solids were synthesized from a natural montmorillonite clay (STx-1) using the template method with a non-ionic surfactant and exchanged with Fe3+, Cu2+ and Fe3+-Cu2+; additionally, MgO/surfactant-clay solids impregnated with different contents of Zn, Fe-Zn and Cu-Zn were also prepared. The solids were characterized by using XRF, XRD, surface area, TPR and TGA-DTG. An increase in the surface area, pore volume and mesoporosity of STx-1 modified with surfactant was observed. The natural clay modified with surfactant and exchanged with copper cation enhanced the H2S breakthrough capacity. The STx-1 clay impregnated with zinc improved H2S removal, which increased with increasing the zinc content. 2011 artículo científico 0254-0770 https://www.redalyc.org/articulo.oa?id=605767224009 en http://www.redalyc.org/revista.oa?id=6057 Revista Técnica de la Facultad de Ingeniería, Universidad del Zulia application/pdf Universidad del Zulia Revista Técnica de la Facultad de Ingeniería, Universidad del Zulia (República Bolivariana de Venezuela) Num.1 Vol.34
