Abstract

The formation of carbon monoxide (CO) from glucose and cellulose by the treatment with various ionic liquids was studied. Ionic liquids with an imidazolium structure as cation and the chloride or acetate as anion were used. Additionally, 1,8-diazabicyclo [5.4.0]undec-7-ene (DBU) was employed as an additive. CO was generated from glucose with a maximum yield of 0.57 mol% after 90 min of treatment at 120 °C in the reaction system in which DBU was added to the ionic liquid. Pyrolysis above 600 °C has been commonly employed for the gasification of lignocellullosics to produce useful gases such as CO. However, this study has revealed that gasification of lignocellullosics to produce CO can occur at significantly lower temperature, specifically at 120 °C.
