Xie, Zean published the artcileSeparation of methyl glycosides and glycerol from aqueous fraction of methyl bio-oils using nanofiltration, Category: esters-buliding-blocks, the main research area is methyl glycoside glycerol aqueous fraction bio oil nanofiltration.
The feasibility of separating small mol. organic compounds in the aqueous fraction of Me bio-oils (AFMBO) using nanofiltration (NF) and reverse osmosis (RO) membranes was studied. Four kinds of com. available NF and RO membranes were studied preliminarily by using model solutions (aqueous solution of Me glycosides and glycerol). The membrane module was spiral wound, which is a more suitable format for industrialization than the flat-sheet format for dead-end filtration. The NF400-600 membrane exhibited the best separation performance; the permeate flux was 48.6 L/(m2·h), the Me glucosides (MEG) rejection ratio was 95.4%, and the transmission of glycerol was 81.0% with an initial concentration of 10 g/L (0.4 MPa, 45 °C). Compared with the model solution, the NF performance of AFMBO, which included permeate flux, rejection of MEG, transmission of glycerol, and separation of the other components in AFMBO, was investigated. The more complex constituents of AFMBO led to NF400-600 permeability and separating property decline compared with the model solution in the same operating conditions; meanwhile more serious and even irreversible membrane fouling occurred. This research provided a reference for membrane separation industrial feasibility and application of AFMBO.
