Abstract Ketonization of carboxylic acids is one the crucial reactions to produce sustainable bio-fuel and bio-chemicals from pyrolysis oil wood. using different mixed solutions acids, furfural, hydroxyacetone has been explored understand influence co-feed reactants on performance ketonization acid over selected CeZrOx catalyst. Furfural (7% in water) inhibited catalytic activity for acetic (20...

Abstract The one-pot production of a relevant chemical such as 1,5-pentanediol (1,5-PDO) from sustainable sources (furfural) is key reaction to compete with existing fossil sources. This work provides new evidence on the influence starting reagent, features layered double hydrotalcite (LDH)-derived catalysts in form mixed metal oxides (MMO) and conditions productivity 1,5-PDO under batch condit...

Whole-cell biocatalysis using Antarctic bacteria is presently hampered by a lack of genetic information, limited gene tools and critically, poor range cultivation conditions. In this work, biological engineering strategy was employed for developing Pseudomonas extremaustralis, metabolically-versatile biopolymer-producing bacterium, as new whole-cell biocatalytic host. For purpose, cloning plasm...

Dilute H(3)PO(4) (0.0-2.0%, v/v) was used to pretreat corn stover (10%, w/w) for conversion to ethanol. Pretreatment conditions were optimized for temperature, acid loading, and time using central composite design. Optimal pretreatment conditions were chosen to promote sugar yields following enzymatic digestion while minimizing formation of furans, which are potent inhibitors of fermentation. T...

The mol-ecule of the title Schiff base compound, C(7)H(8)N(2)OS(2), prepared by the reaction of methyl dithio-carbazate and furfural in an ethanol solution under reflux, adopts an E configuration; the dithio-carbazate and furan units are located on opposite sides of the C=N double bond. The planar dithio-carbazate group is twisted slightly with respect to the furan ring, making a dihedral angle...

The degradation compounds formed during pretreatment when lignocellulosic biomass is processed to ethanol or other biorefinery products include furans, phenolics, organic acids, as well as mono- and oligomeric pentoses and hexoses. Depending on the reaction conditions glucose can be converted to 5-(hydroxymethyl)-2-furaldehyde (HMF) and/or levulinic acid, formic acid and different phenolics at ...

The multi-step, aqueous phase hydrogenation kinetics of furfural (FUR) to furfuryl alcohol (FA), 2-methylfuran (2MF), tetrahydrofurfuryl (THFA) and 5-hydroxy-2-pentanone (5H2P) over Pd-TiO2 on an activated carbon catalyst (derived from a monolith structure) was studied (180 °C, 2.1 MPa). Titanium addition created metal–acid functional promoted 5H2P synthesis furfural. A Langmuir-Hinshelwood mod...

The aldol condensation of model compounds furfural and acetone on the selected base catalysts have been performed. The activity of MgO was compared with industrially produced hydrotalcite and the series laboratory prepared hydrotalcites. Si×MAl2O4 hydrotalcites (M = Mg, Zn, Ni, Co, Cu, and Fe) were prepared by the solgel method at low calcination temperature of 300°C. The properties of the cata...

Integrated permeate channel (IPC) flat sheet membranes were examined for use as a reverse membrane bioreactor (rMBR) for lignocellulosic ethanol production. The fermenting organism, Saccharomyces cerevisiae (T0936), a genetically-modified strain with the ability to ferment xylose, was used inside the rMBR. The rMBR was evaluated for simultaneous glucose and xylose utilization as well as in situ...
