Abstract
The present invention relates to a process for selectively solubilizing and removing lignin and hemicellulose components of cellulosic biomass and obtaining a cellulosic feedstock having a higher proportion of cellulose, as compared to the biomass from which it is derived, and having a greater cellulose Crystallinity Index. In particular, the process comprises: i) contacting cellulosic biomass with a basic ionic liquid having a basic anion selected from one or more alkylcarbonates; and ii) obtaining a cellulosic feedstock which has a higher proportion of cellulose component, as compared with the cellulosic biomass from step i).
