Estudio de la remoción de sulfuro de hidrógeno empleando extrudados de arcilla ecuatoriana en corriente de biogás

Abstract

Abstract: 2 ABSTRACT In this work, the removal capacity of the H2S, using clay Ecuadorian, modified with Na, Cu, and Zn and morphologically adapted to the shape of extrudates was studied. The removal capacity of the H2S, was evaluated using a fixed bed filter containing the sorbent, coupled to a flow of biogas, with 2% H2S, using a flow of 1mL/s, at a gauge pressure of 2 psig, ambient temperature of 30°C. The flow of biogas came from a bioreactor anaerobic treatment of vinasse. The concentration of H2S to the inlet and the outlet of the filter was determined, through blisters GASTEC 4H and 4HH, using a suction pump GASTEC GV-100-S-TR with capacity for suction of 50-100 ml. The solid that gave better results was ST15Na12Fe15Cu15Zn, which lasted for a time of 920 minutes before becoming saturated, stirring mili 2.67 moles of H2S/gram of sorbent. While the industrial activated carbon, used as a reduction in the concentration of H2S presented a removal capacity of 2.40 mili moles of H2S/gram of carbon and was saturated to 540 minutes.
