This study established a novel process using sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL) for robust and efficient bioconversion of softwoods. The process consists of sulfite treatment of wood chips under acidic conditions followed by mechanical size reduction using disk refining. The results indicated that after the SPORL pretreatment of spruce chips with 8-10% bisu...

Abstract Here, tetrakis(hydroxymethyl)phosphonium chloride‐protected colloidal iridium nanoparticles were deposited by sol‐immobilisation on three different supports (CeO 2 , NiO and TiO ) investigated for the liquid‐phase direct hydrogenation (H atmosphere) catalytic transfer – CTH (N of furfural to study effect H donor. The occurrence strong‐metal support interactions in 1 wt % Ir/CeO catalys...

Fructose can be efficiently converted to 5-hydroxymethylfurfural by using the functionalized ionic liquid 3-(2-chloroethyl)-1-methylimidazolium chloride as both solvent and catalyst in the presence of water. This work advances the field and is distinct from earlier efforts in the sense that the observed yields of HMF from fructose are rather high and the reaction conditions rather mild and neut...

Effects of furfural on the aerobic metabolism of the yeast Saccharomyces cerevisiae were studied by performing chemostat experiments, and the kinetics of furfural conversion was analyzed by performing dynamic experiments. Furfural, an important inhibitor present in lignocellulosic hydrolysates, was shown to have an inhibitory effect on yeast cells growing respiratively which was much greater th...

An alternative to 5-hydroxymethyl-2-furfural (HMF), which is a promising furan derivative that can be used as starting material for the preparation of non-petroleum-derived polymeric materials from sugars, 5-acetoxymethyl-2-furfural (AMF). The less-hydrophilic acetyl group AMF has advantages over hydroxy HMF in terms thermal stability and isolation. In previous studies, fructose been along with...

The conversion of 5-(hydroxymethyl)furfural (5-HMF) into 2,5-dimethylfuran (2,5-DMF) via cascade hydrogenation and hydrogenolysis over metallic catalysts has been considered a promising method to produce high-energy-content biofuel. Understanding the adsorption reactants, reactions, desorption byproducts is essential for developing efficient selective catalysts. Herein, most plausible reaction ...
