Abstract

 The search for alternative processes for the removal of sulfur compounds in fuels is a constant, as environmental legislation around the world is becoming increasingly rigorous regarding reductions in the fraction of these compounds in fuels. This study evaluated the adsorptive capacity of zeolite ZSM-35 pure and impregnated with 2.5% and 5% molybdenum in the removal of the thiophene, organosulfur compound, of a model gasoline. The materials were prepared via wet impregnation and characterized by XRD, SEM, thermal analysis (TG/DTG). Adsorption kinetics were performed at temperatures of 303 K and 313 K in a batch system under agitation of 140 rpm for 12 hours. The kinetics of adsorption was evaluated by kinetic models of pseudo first order, pseudo second order, intraparticle diffusion and Elovich. The results showed that the increase in temperature and the concentration of molybdenum in the structure of the zeolite has an influence on the increase of the sulfur removal efficiency of the gasoline.
