Depolymerization of microcrystalline cellulose to value added chemicals using sulfate ion promoted zirconia catalyst.
Abstract The transformation of lignocellulosic biomass to value added chemicals in a synergetic effect of sulfated zirconia (SZ) catalyst and ionic liquid was found to effectively depolymerize microcrystalline cellulose (MCC) to sugars and dehydrate sugars to 5-hydroxylmethylfurfural (5-HMF) and levulinic acid (LA). SZ was catalyst synthesized by wet impregnation method with predetermined concentration of sulphuric acid and […]
