Sorbitol and glycerin, dideoxyhexitol, and trideoxyhexitol are under consideration as a new generation green energy platform, instead of syngas, to produce bio-fuels,2,3 chemicals, and hydro- gen.4,5 Sorbitol is generally obtained via a two-step process, that is, hydrolysis of cellulose in acidic water and then by further hydrogenation.
Sep 21, 2018 · However, several technological challenges, such as elevated reaction temperature (220280 °C), high H 2 pressure (410 MPa), uncontrollable side reactions, and intensive capital investment, have resulted in a bottleneck for the further development of existing APH processes.

Dec 10, 2013 · Under the applied reaction conditions, optimal results (63.2 % yield in hexitols with a selectivity for sorbitol of 57.9 % at complete conversion of cellulose, and 97.1 % yield in hexitols with a selectivity for sorbitol of 95.1 % at complete conversion of cellobiose) were obtained using a RuPTA/MIL100(Cr) catalyst with loadings of 3.2 wt DOI:10.1002/cssc.201301123 Pt Nanocatalysts sorbitol directly.[5,912] Nevertheless, few solid catalysts can obtain sorbitol with high yield when microcrystalline cellulose is used as feedstock except under harsh reaction condi-tions. In the conversion of cellulose to sorbitol, the catalyst used can accelerate hydrolysis or/and hydrogenation reactions (Scheme 1).

China is the major producer of sorbitol in the world. It accounts for around 40-45% of the global production capacity of the sorbitol.
H3PW12O40/SiO2 for sorbitol dehydration to isosorbide 3. Typical Procedure for Dehydration of Sorbitol The sorbitol dehydration measurements were performed at at-mospheric pressure, in a fixed bed reactor packed with 0.5 g of the catalysts. The gas employed as carrier was nitrogen. The reaction feed, a sorbitol aqueous solution, was introduced into the reaction system by a syringe pump.
Aug 29, 2002 · The equilibrium constant for reaction (1) per mole of CO 2 is of the order of 10 8 at 500 K, indicating that the conversion of sorbitol in the presence PEER-REVIEWED ARTICLE bioresources.nanoparticles played an important role in the hydrogenation of D-glucose into D-sorbitol, and the Ru particle was widely dispersed all over the support surface. In addition, the Ru/CCD catalyst was stable during the reaction and was reused for up to five successive runs with a slight decrease in D-sorbitol
sorbitol can reach above 90% under the catalyzing of Ru-based catalysts (Zhang et al. 2011). However, the selectivity to sorbitol decreased markedly during the hydrolytic hydrogenation of cellulose, and downstream molecules such as ethylene glycol and propylene glycol were produced at the same time (Palkovits et al. 2010). Furthermore, Product Control and Insight into Conversion of C6 The hydrogenation of sugar or biomass are usually catalyzed by some support catalyst based on noble metal such as Ru, Pd and Pt. Perrard et al. have achieved complete conversion of glucose hydro-genation over a Ru catalyst loaded on activated carbon with a sorbitol selectivity of 99.2 %. And xylitol can be hydrogenated
Abstract Alcohols have a wide range of applicability, and their functions vary with the carbon numbers. C6 and C4 alditols are alternative of sweetener, as well as significant pharmaceutical and ch Secondary hydrogenation device for sugar alcohol Mar 05, 2009 · The secondary hydrogenation device for sugar alcohol structurally comprises a primary reaction kettle, a secondary reaction kettle and a sedimentation tank, wherein the liquid outlet of the primary reaction kettle is communicated with the liquid inlet of a hydrogenation liquid intermediate tank through a pipeline after being connected in
