Remoção de sulfeto em biogás utilizando nanoparticulas de óxido de ferro

Abstract

Biogas is a gas mixture, which is the result of anaerobic degradation of organic matter deposited in biodigesters, which has traces of sulfide in its composition. Sulfide in turn is responsible for corrosion in the biogas purification system. To verify the degree of purification of the biogas in relation to the sulfide, characterization analyzes of the iron oxide nanoparticle were carried out, which was our adsorbent, reaction kinetics, where it was verified that the time for the reaction to occur is approximately 10 minutes and to finish the study was carried out the chemical adsorption, where a curve was made for comparison purposes, also called the blank of the analysis and with the addition of nanoparticles. You chose to work in a range around 1.0x10-4 mol / L. This concentration is the general average found in biodigesters. The characterization of the nanoparticle showed results around 50 nm for particle size, and purification of the solution by adsorption using nano iron oxide particles is considered possible. The values obtained in this work indicate that 1 gram of the adsorbent purifies at least 1.15L of biogas.
