Hydrogenation/dehydrogenation reactions: isopropanol dehydrogenation over copper catalysts

Selective Furfural Hydrogenation to Furfuryl Alcohol Using Cu-Based Catalysts Supported on Clay Minerals

“…9), and they can be deconvoluted into four contributions: 284.8 eV (C-C bonds), 286.2 eV (C-OH or C-O-C bonds), 287.2 eV (C = O bonds) and 288.7 eV (O-C = O bonds). In this sense, according to the study of several authors on the adsorption heats of FUR, FOL and MF in Cu-based catalysts, it can be assumed that that FOL and mainly FUR are strongly adsorbed on active sites [31,45]. Therefore, the band observed between 286.2 and 288.7 eV can be attributed to the adsorption of reactants and products on the catalyst surface.…”

Applications and Preparation Methods of Copper Chromite Catalysts: A Review

“…The dehydrogenation of alcohols to aldehydes or ketones is a well-known industrial process, and these reactions are primarily carried out on copper catalysts because of their high selectivity to the dehydrogenation product [27]. Catalytic dehydrogenation of alcohols plays a key role in the chemical industry particularly in the synthesis of various pharmaceuticals and fine chemicals apart from bulk chemicals.…”

“…(7). Copper chromite catalysts possess high selectivity and satisfactory activity [27,100] for isopropyl alcohol dehydrogenation (eqn. 11):…”

“…Many research projects sanctioned [12,[26][27][28][29], several Ph.D. theses approved [30][31][32][33][34], a number of patents granted [35][36][37][38][39] and numerous studies [14,15,17,19,[40][41][42] have been conducted on innovative preparation methods and utilizations of the copper chromite catalysts. However, preparation methods and utilizations of such catalysts have hardly been reviewed so far.…”

Regeneration of granular activated carbon saturated with acetone and isopropyl alcohol via a recirculation process under H2O2/UV oxidation

“…4, where the trend of IPA disappearance was found closely to match that of acetone generation. It is believed that this dehydrogenation involves the abstraction of hydrogen atoms by • OH free radicals from the hydroxyl group ( OH) of IPA (CH 3 COH CH 3 ) molecules to form the corresponding acetone (CH 3 COCH 3 ) molecules [31,32]. Although IPA disappearance rates in both modes were much faster than those of acetone ( Figs.…”
