We report on the markedly improved stability of a novel 2-bed catalytic system, as compared to that conventional 1-bed steam reforming catalyst, for production H2 from acetic acid. The system consists (i) basic oxide ketonization catalyst conversion acid acetone, and (ii) Co-based both beds placed in sequence within same unit operation. Steam catalysts are particularly prone deactivation when acid, used here model compound aqueous fraction bio-oil. Catalysts consisting MgAl2O4, ZnO, CeO2,...
Warm (250–450 °C) cleanup of coal- or biomass-derived syngas requires sorbents and catalysts to protect downstream conversions. We report first a sequential ZnO bed operation in which the capacity is optimized for bulk desulfurization at 450 °C, while subsequent removal sulfur parts-per-billion levels can be accomplished lower temperature approximately 300 °C. At this temperature, gaseous (H2S COS) could adsorbed equally well using ZnO, both with without presence H2O feed, suggesting direct...
The electrooxidation of ethylene glycol on a Pt/C catalyst was investigated over range temperatures (333 - 373 K) using newly developed high pressure electrochemical reforming reactor. Two distinct oxidation peaks were visible the positive sweep reaction. reactor able to maintain steady state current reaction potentials implying catalytic system for glycol.
Electrocatalytic reforming (ECR) of ethylene glycol (EG) was studied in an effort to determine the feasibility ECR for hydrogen production from biomass. Measurements were made a proton exchange membrane (PEM) reactor with Pt/C anode and cathode Nafion electrolyte. Electrooxidation EG aqueous phase over temperature range 40--137°C. Reaction progress followed by cyclic voltammetry, potential-step chronoamperometry, chromatographic analysis reaction products. Sustained occurred at overpotential...
