Innovative Process for the Purification of Green Aviation Fuel Additive “Dimethoxymethane”: Pervaporation

Abstract

The aim of this study is purification of aviation fuel additive “dimethoxymethane” by using pervaporation process. Polyetherimide (PEI) membrane was utilized for the purification of dimethoxymethane from dimethoxymethane/methanol mixtures. Membranes were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Purification tests were performed in different feed methanol concentration and operation temperature. Methanol selectivity value was obtained as infinite. The results obtained show that high purity dimethoxymethane green aviation fuel additive can be achieved by pervaporation process. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
