Abstract
Reivindicación 1: Un proceso para producir etanol que comprende las etapas de: pasar una corriente gaseosa que comprende hidrógeno y un ácido alcanoico en la fase de vapor a través de un catalizador de hidrogenación para formar un producto que comprende un alcohol y menos de aproximadamente el 0,25% de éter en base al peso total del producto, en donde el catalizador de hidrogenación se produce por medio del proceso que comprende las etapas de: impregnación de un modificador de soporté a partir de metatungstato de amonio, heptamolibdato de amonio tetrahidratado, ácido silicotúngstico hidratado, ácido fosfotúngstico, ácido silicomolíbdico, ácido fosfomolíbdico, oxalato de niobio hexahidratado u óxido de vanadio en un soporte para formar un primer soporte impregnado; calcinación del primer soporte impregnado para formar un soporte calcinado; impregnación de uno o varios metales activos a partir de uno o varios precursores de metales en el soporte calcinado para formar un segundo soporte impregnado, en donde uno o varios metales activos están seleccionados del grupo que consiste en hierro, cobalto, níquel, rutenio, rodio, platino, paladio, osmio, iridio, titanio, zinc, cromo, molibdeno, tungsteno, estaño, lantano, cerio, manganeso y oro; y calcinación del segundo soporte impregnado para formar el catalizador.Claim 1: A process for producing ethanol comprising the steps of: passing a gas stream comprising hydrogen and an alkanoic acid in the vapor phase through a hydrogenation catalyst to form a product comprising an alcohol and less than about 0.25% ether based on the total weight of the product, wherein the hydrogenation catalyst is produced by the process comprising the steps of: impregnation of a carrier modifier from ammonium metatungstate, tetrahydrated ammonium heptamolybdate, hydrated silicotungstic acid, phosphotungstic acid, silicomolibic acid, phosphomolibic acid, niobium oxalate hexahydrate or vanadium oxide in a support to form a first impregnated support; calcination of the first impregnated support to form a calcined support; impregnation of one or more active metals from one or more metal precursors in the calcined support to form a second impregnated support, wherein one or more active metals are selected from the group consisting of iron, cobalt, nickel, ruthenium, rhodium , platinum, palladium, osmium, iridium, titanium, zinc, chromium, molybdenum, tungsten, tin, lanthanum, cerium, manganese and gold; and calcination of the second support impregnated to form the catalyst.
