The dehydrogenation of methanol to methyl formatePart I: Kinetic studies using copper-based catalysts

Simultaneous production of dimethyl ether (DME), methyl formate (MF) and hydrogen from methanol in an integrated thermally coupled membrane reactor

“…Kinetics of the dehydrogenation of methanol to MF has been examined for a commercial copper-chromite catalyst. Following is the rate expression obtained by Huang et al [62,68]:…”

Applications and Preparation Methods of Copper Chromite Catalysts: A Review

“…40 and 41) can occur in the PROX system. CO + ½ O2 → CO2 ∆H 0 = -282.98 kJ/mol (40) H2 + ½ O2 → H2O ∆H0 = -241.82 kJ/mol (41) CO is a typical by-product in the production of hydrogen by reforming of alcohols or hydrocarbons and must be reduced down to ppm levels in order to be used as feed for proton-exchange membrane fuel cells. Up to date, several options for CO removal have been studied and the selective oxidation (CO-PROX) is considered one of the most H2 + CO + O2 (air) → CO2 + H2 (42) Many industrial applications using H2 as a feedstock require a H2 stream containing a little CO.…”

“…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.…”

Production of high-value products including gasoline hydrocarbons from the thermochemical conversion of syngas

“…Methanol can be produced indirectly from the gasification of biomass through the process listed earlier and serves as a reactant to form many other high valued products such as acetic acid [46,47], acetic anhydride [47], BTX [48], chloromethanes [49], dimethyl oxalate [50], dimethyl carbonate [51], ethanol (and other higher alcohols [52]), ethylene [53] , ethylene glycol [54], formaldehyde [55,56], methyl acetate [57], methyl chloride [58], methyl formate [59][60][61], methyl esters [62,63], methyl glycolate [211,64], MTBE [65][66][67][68], methylamines [69][70][71], olefins, [72][73][74], propylene [75] and vinyl acetate [76]. Methanol can be the reactant to form many higher alcohols but one common practice is methanol coupling to form ethanol.…”
