摘要
Biomethane (CH4) combustion, as a renewable fuel, is an excellent alternative to decrease the CO2 emissions released into the atmosphere. However, this combustion requires catalysts which are normally poising by the presence of SO2 gas. Then, an auxiliary material capable of selective capturing the contaminant SO2 is necessary. In this work, the SO2 gas adsorption performance of a high stable Al(III) MOF known as DUT-4 was studied. In addition to the high SO2 uptake, in dry and wet conditions, and a high SO2 adsorption cyclability, we have explored for the first time a promising purification of CH4 in presence of SO2, taking into account the high affinity for SO2, even at a low concentration of SO2 (a molar gas composition of 1:99 SO2:CH4).
