Preparation of furfural and reaction kinetics of xylose dehydration to furfural in high-temperature water

Kinetics of furfural production by dehydration of xylose in a biphasic reactor with microwave heating

Quantitative Formation of Furfural from Xylose

A study has been made of various methods of distillation of solutions of furfural and of xylose with the object of increasing the 88-percent yield of furfural obtained from xylose by the present standard m ethod of distillation. Sources of error that have been considered are: Decomposition of furfural, volatilization of furfural, effect of rubber stoppers used in the distillation procedure, inc...

Kinetics and inhibition effects of furfural and hydroxymethyl furfural on enzymes in yeast

Fermentatively produced ethanol from lignocellulose by yeast is a renewable alternative to fossil fuels. However, inhibitors originating from the breakdown process of the raw material decrease the fermentation rate. Previous studies have made known inhibition effects by the furan compounds furfural and hydroxymethyl furfural (HMF). In the current work, the kinetics and inhibition effect of furf...

Microemulsion and Sol-Gel Synthesized ZrO₂-MgO Catalysts for the Liquid-Phase Dehydration of Xylose to Furfural.

Two series of catalysts were prepared by sol-gel and microemulsion synthetic procedure (SG and ME, respectively). Each series includes both pure Mg and Zr solids as well as Mg-Zr mixed solids with 25%, 50% and 75% nominal Zr content. The whole set of catalysts was characterized from thermal, structural and surface chemical points of view and subsequently applied to the liquid-phase xylose dehyd...

Selective Preparation of Furfural from Xylose over Sulfonic Acid Functionalized Mesoporous Sba-15 Materials

Sulfonic acid functionalized mesoporous SBA-15 materials were prepared using the co-condensation and grafting methods, respectively, and their catalytic performance in the dehydration of xylose to furfural was examined. SBA-15-SO3H(C) prepared by the co-condensation method showed 92–95% xylose conversion and 74% furfural selectivity, and 68–70% furfural yield under the given reaction conditions...
