abstract
Efficient recovery of ionic liquid (IL) from aqueous mixture of ILs and sugars (which derived from
enzymatic or chemical catalyzed hydrolysis of ILs-pretreated biomass) is a major drawback for commercialization
of biofuel and platform chemicals production from biomass utilized ILs as pretreatment
solvent. In this study, simulated moving bed (SMB) chromatography equipped with ion exclusion column
(containing [Emim]+ cation) was investigated to separate sugars (glucose and xylose) which are the main
products from biomass hydrolysate and 1-Ethyl-3-methylimidazolium acetate (EmimAc) which is the ILs
used for biomass pretreatment. A four-zone SMB system with a configuration of 2-2-2-2 (2 ion exclusion
columns in each zone) was used to recover glucose, xylose and EmimAc from their aqueous mixture with
yield of 71.38, 99.37 and 98.92%, respectively. Moreover, the optimization of SMB zone configuration by
simulation results in a complete recovery of ILs. This result indicates that for the first time, ion exclusion
SMB chromatography could be used for complete recovery of ILs from aqueous sugar mixture.
