Faculty Mechanical, Maritime and Materials Engineering Department Process and Energy Date 2012-05-03 Abstract The invention is directed to a process for the production of furfural from pentoses and/or water soluble pentosans, said process comprising converting the said pentoses and/or water soluble pentosans in aqueous solution in a first step to furfural and in a second step feeding the aqueous solution containing furfural obtained in the first step to the top of a distillation column to produce an aqueous, liquid downflow, which column is heated at the bottom part thereof, using at least one reboiler to produce an upflow steam flow, recovering a water and furfural containing vapour product stream from the top of the said column, compressing the said vapour flow and condensing it on the hot side of the reboiler at the bottom of the said column to produce sufficient steam in the said bottom part of the column to produce the said upflow steam flow, and to recover an aqueous furfural containing solution as the condensate in the reboiler.
