Abstract

La presente invención se refiere a la remoción H2S que puede estar contenido en biogás o en gases de procesos industriales en concentraciones de 35-15000 ppm. Por medio de nanopartículas de ferrita de manganeso MnxFe3-xO4 con x=0%, 0.1%, 0.3 % y 0.5%, obtenidas por medio de co-precipitación química a partir soluciones de cloruros y a una temperatura menor de 100 grados Celsius. Con área superficial de 142-240 m2/g y tamaño de partícula de 7-9 nm. Y que se realiza mediante un conjunto de componentes como: válvula reguladora de presión, un medidor de flujo, un rector tipo flujo pistón, una manómetro, una válvula tres vías, un equipo de medición de biogás, un lavador de gases y un quemador del biogás.
