Process For The Production Of Furfural From Pentoses

10 May 2012
Congratulations to our Associate Consultant Gianluca Marcotullio (and also Wiebren) on the publication of United States Patent Application 20120108829!

Gianluca's PatentGianluca has a special business focus on technologies that reduce energy (= steam reduction in furfural plants) and complements the DalinYebo team with his particular interest and knowledge in the field of process development for new generation biorefineries. Gianluca has a personal interest in the furfural chemistry and technology, which is published in his thesis "The Chemistry And Technology Of Furfural For Modern Lignocellulose-Feedstock Biorefineries (Furfural, the sleeping beauty)" and now also in the above United States Patent Application:

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 to produce an upflow water vapour flow, recovering a gaseous water and furfural containing product stream from the top of the said column, compressing the said vapour flow and condensing it on the hot side of a reboiler at the bottom of the said column.
