摘要:The dynamic adsorption/desorption behavior of VOCs (C7H8) was evaluated for mesoporous SBA-15 silicas with four kinds of morphologies and pore sizes on a fixed bed unit. The SBA-15 silica with interconnected rodlike morphology exhibited exceptionally good breakthrough behavior, a higher adsorption capacity, and better desorption performance for toluene. The large dynamic VOC capacity of the interconnected rodlike silica was attributed to the pore system of the micropores and mesopore size, group-togethering rods which can aggregate to enhance the ability of adsorption, together with the smoother surface.
