And a vapor-phase acid-catalyzed hydrolysis of the Lewis acid co-furfural method of preparing
2013
The present invention belongs to the technical field prepared furfural, particularly relates to a method and a gas phase acid-catalyzed hydrolysis of the Lewis acid were prepared using furfural. This method is mixed biomass feedstock and an aqueous solution of a Lewis acid, hydrochloric acid vapor was placed in a tubular reactor, sparged with nitrogen evacuated, vaporized and then passed from one end of the tubular reactor, the tubular reactor from another One end of the condensate collected condensate that is furfural crude product. The present invention adds a Lewis acid promoter, to improve the yield of furfural, while avoiding the corrosion of equipment, no acid effluent discharge, avoid environmental pollution.
