Abstract
A method for adsorbing volatile organic compounds (VOCs) derived from organic matter comprises adsorbing the VOCs onto palladium doped ZSM-5, optionally at ambient temperature. The organic matter can be perishable organic goods such as food, including fruit and/or vegetables, horticultural produce, including plants and/or cut flowers, or refuse. The palladium doped ZSM-5 has a Si:Al ratio of less than or equal to 100:1 and preferably has a palladium content of from 0.1 wt % to 10.0 wt % based on the total weight of the doped ZSM-5.
Claims23
A method for adsorbing volatile organic compounds (VOCs) derived from organic matter comprising the step of adsorbing the VOCs onto palladium doped hydrogen ZSM-5, wherein the Si:Al ratio of the hydrogen ZSM-5 is less than or equal to 100:1.
