TÓM TẮT
The acid gas containing trace amount of H2S from the crude natural gas or from biogas is nowadays treated by selective oxidation process. The presence of benzene, toluene, and xylene (BTX) in the acid gas effluent, even in very small concentrations, can alter the chemical kinetics of H2S oxidation significantly and often causes rapid catalyst deactivation due to hydrocarbon deposition, especially for the metal-based catalysts. In order to reduce such deactivation problem the BTX compounds were removed through enrichment/combustion process before the H2S processing. It is of interest to develop new catalyst with high resistance towards BTX deactivation process in order to reduce the overall cost of the process
