Abstract:
A method to convert cellulose contained within lignocellulose solids to form hydroxymethylurfural which comprises:providing lignocellulose solids containing cellulose, and providing a vessel containing an aqueous acidic solution, and adding said lignocellulose solids to said vessel, and subjecting cellulose contained within said lignocellulose solids to hydrolysis by said aqueous acidic solution to form glucose, and subjecting said glucose to form hydroxymethylurfural, and removing said hydroxymethylurfural from said vessel, and separating solids, remaining from hydrolysis, from said vessel thereby producing hydroxymethylurfural from cellulose contained within lignocellulose solids and separating solids remaining from hydrolysis from the vessel.
