Journal ArticleDOI
Hydrogenolysis Goes Bio: From Carbohydrates and Sugar Alcohols to Platform Chemicals
TL;DR: Past and present developments in hydrogenolysis reactions are highlighted, with special emphasis on the direct utilization of cellulosic feedstocks, to bridge currently available technologies and future biomass-based refinery concepts.
Journal ArticleDOI
Hydrogenolysis of cellulose combining mineral acids and hydrogenation catalysts
TL;DR: In this paper, a catalytic system capable of reaching high performance in the hydrogenolysis of cellulose at low reaction temperature and short reaction times has been developed, where supported noble metal catalysts based on Pt, Pd and Ru have been combined with dilute mineral acids.
Journal ArticleDOI
Heteropoly acids as efficient acid catalysts in the one-step conversion of cellulose to sugar alcohols
TL;DR: Heteropoly acids together with supported ruthenium catalysts show not only high activity but also remarkable selectivity to sugar alcohols reaching up to 81% yield of C(4) to C(6) sugar Alcohols in only 7 h at 160 °C.
Journal ArticleDOI
Role of water in metal catalyst performance for ketone hydrogenation: a joint experimental and theoretical study on levulinic acid conversion into gamma-valerolactone
Carine Michel,Jeremie Zaffran,Agnieszka M. Ruppert,Joanna Matras-Michalska,Marcin Jędrzejczyk,Jacek Grams,Philippe Sautet +6 more
TL;DR: It is demonstrated that water is responsible for the enhanced reactivity of Ru under aqueous phase conditions in the hydrogenation of ketones such as the conversion of levulinic acid into gamma-valerolactone.
Journal ArticleDOI
Glycerol etherification over highly active CaO-based materials: new mechanistic aspects and related colloidal particle formation
Agnieszka M. Ruppert,Johannes D. Meeldijk,Bonny W. M. Kuipers,Ben H. Erné,Bert M. Weckhuysen +4 more
TL;DR: A plausible alternative reaction scheme for glycerol etherification is presented, which considers the facilitation of the hydroxyl leaving process and the stability of the catalytic solids under study was investigated and it was found that colloidal CaO particles can be spontaneously generated during reaction.
