Sulphur removal is significant for fuels used as hydrogen sources for modern fuel cell applications. A high performance membrane adsorber with metal organic frameworks (MOFs) has been fabricated. The architecture of the three-dimensional membrane channels provided multiple functional sites and an efficient method of incorporating [Cu 3 (BTC) 2 ] particles into a polyimide (PI) matrix. The properties of the MOF-based membrane adsorber, including the adsorption contribution, regeneration behavior and effect of fuel species, have been investigated. In all cases, the inlet fuel can be desulfurized to below 0.1 mg L 21 , which means that the outlet fuel can be used as a sulphur-free hydrogen source for fuel cell applications. The related discussions can propose some general suggestions for the separation of organic-organic mixtures involved in current energy and environmental problems. The desulfurization capabilities of the membrane adsorber are likely to play an influential role in the reduction of motor vehicle pollution and the development of fuel cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
