Abstract

Biofuels and chemicals can be produced from the lignocellulosic biomass would be promising platform in the upcoming decades. The maize cob is selected as lignocellulosic biomass to synthesis chemicals. The maize cob treated with meagre concentration of dilute sulfuric acid (H2SO4) dehydrated with Tetrahydrofuran (THF) co-solvent and water in the ratio of 1:1 results with furfural formation. The maize cob sample acid catalysed dehydration process at 1, 2.5, 5 and 10% dilute H2SO4 is substantial for sugar compounds production, these compounds can be further fermented to produce liquid fuels viz., bioethanol, biobutanol in an efficient manner. The  maize cob treated with 0.25, 0.5 and 0.75% of dilute H2SO4 dehydrated with THF co-solvent and water (1:1) results with furfural formation and highest concentration was found in 0.5% acid catalyzed. The furfurals obtained can be downstream processed to recover and can be used as fuel precursor.
