The environmentally obnoxious nature of Nitrogen in fuel oils requires serious attention for its removal. In this work, a novel hybrid matrix membrane was prepared by introducing MoO3 nanoparticles into poly (ether-block-amide) (PEBAX2533) and was in turn used for the pervaporative separation of pyrrole/n-heptane mixtures. The interactions between the membrane, pyrrole and n-heptane were investigated by swelling experiments. Pervaporative separation performance of PEBAX membranes revealed higher selectivity for pyrrole from its mixture with n-heptane, which further increased with increasing MoO3 contents in membrane along-with correspondingly increasing the total flux and the separation factor as well. At 2000 µg·g− 1 pyrrole concentration and 30°C temperature, the total flux and the separation factor reached the maximum values of 2.46 kg•m− 2•h− 1 and 17.58, respectively. Attributed to the outstanding separation performance of PEBAX membranes, this work may provide a useful insight into the viable removal of nitrogenous compounds from gasoline via pervaporation.
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.
