At Delft University of Technology theoretical and experimental research is carried out towards selective production of furfural from renewable biomass. Furfural is an interesting molecule that has been identified as a platform chemical for a multitude of chemical products and fuel (additives).Acidic biomass hydrolysis and subsequent dehydration of the obtained C 5 sugar xylose leads to furfural. The reaction selectivity is a point of concern for reactor design, as furfural can further react to loss products. The residue of this process mainly consists of the remaining main biomass constituents, cellulose and lignin. Mineral matter is to a large extent extracted to the acid in the primary hydrolysis. This implies that the residue has the potential to be a better feedstock for thermo-chemical conversion, as e.g. alkali and chlorine species-now extracted-potentially cause different types of problems (slagging, fouling, agglomeration etc.).An interesting option for example might be to convert this improved feedstock into synthesis gas via a gasification process, which then needs to be conditioned and upgraded for the production of green transportation fuels. In this line, a new biorefinery generation is created, which selectively uses the hemi-cellulose part of biomass. An analysis is presented towards current (integrated) concepts for novel, * During the writing of the article our dear friend and colleague Henk Heidweiller passed away, we owe him a word of thanks for his contributions and ideas in the field of furfural production from biomass.

“…Levulinic acid has been of interest for many years as a bifunctional keto-acid but it has never been made on a large scale. Biofine Renewables has developed a thermochemical process that produces levulinic acid, furfural, formic acid and char from a wide variety of biomass feedstocks and have achieved large scale production [5]. New chemistry related to derivatives of levulinic acid has appeared and many are moving to advanced production levels.…”

The rapid and ongoing increase in consumption of petroleum for transportation fuels, chemicals and energy is not sustainable. Therefore, development of technology that uses agricultural, animal, forestry and municipal solid waste as renewable feedstock is critical to the US economy and national security, and presents a significant opportunity for new catalysis, chemistry and process research. This paper will outline recent developments on the conversion of biomass to renewable fuels and chemicals with emphasis on new opportunities for thermochemical catalysis.

“…3,4,19 For example, Biofine 1 patented a process in 1990 that was primarily for levulinic acid production with furfural as a side-product with a yield of approximately 70% of theoretical. [21][22][23] The Vedernikov furfural process increased yields to 75% with less cellulose losses. [24][25][26] Current commercial technology uses steam to strip furfural from the aqueous solution, but even then, the boiling point elevation that results from dissolved sugars in water limits maximum yields to about 75%.…”
