Abstract: A 13X zeolite modified with Cu ions (13X Ex-Cu) by means of an innovative technique was employed as adsorbent for H2S removal from biogas, to obtain a desulfurized fuel suitable for molten carbonate fuel cell systems. Sorbent performance was characterized over a wide range of operating conditions typical of biogas mixtures (high H2S content - 200 and 1000 ppmv; CH4 (60%)/CO2 (40%) matrices) and compared to several conventional sorbents. A sensitivity performance analysis was conducted, varying parameters as space velocity, reactor temperature, gas matrix composition and particles size, finalized to identify the optimal conditions for the studied application.
