description | En vandig lavtemperatursoksidasjon (ALTO) prosess hvor en katalysator eller katalysatorforløper bestående av en fast bærer eller en pulverkomponent og et metall eller en metallkomponent innbefattende kobolt oksideres, reduseres og gjøres katalytisk aktiv for utførelse av karbonmonoksidhydrogeneringsreaksjoner. Koboltkatalysatoren eller koboltkatalysatorforløperen blir således brakt i kontakt ved lav temperatur med en oksidant i nærvær av vann (for eksempel vann hvortil oksidant er tilsatt), tilstrekkelig til å oksidere koboltmetallet eller metallkomponenten av katalysatoren eller katalysatorforløperen. Ved reduksjon blir hydrogeneringsaktiviteten av koboltkatalysatoren forøket. En del av eller alt koboltmetallet i koboltkatalysatorforløperen oksideres til å danne C0-kationer eller okseanioniske typer i det minste under den initiale fasen av reaksjonen. Ved reduksjon, som kan erholdes ved kontakt og behandling av den oksiderte katalysatoren eller katalysatorforløperen med hydrogen eller en hydrogeninneholdende gass vil det katalytiske metall eller metallkomponenten av katalysatoren reduseres til metallisk metall, for eksempel Co, og katalysatoren aktiveres og/eller den katalytiske aktiviteten økes.
An aqueous low temperature oxidation (ALTO) process wherein a catalyst or catalyst precursor constituted of a solids support, or powder component, and a metal, or metals component, inclusive of cobalt, is oxidized, reduced and rendered catalytically active for conducting carbon monoxide hydrogenation reactions. The cobalt catalyst or cobalt catalyst precursor is thus contacted at low temperature with an oxidant in the presence of water (e.g., water to which an oxidant is added), sufficient to oxidize the cobalt metal, or metals component of the catalyst or catalyst precursor. On reduction, the hydrogenation activity of the cobalt catalyst is increased. All or a portion of the cobalt metal of the catalyst precursor is oxidized to form a Co2+ cationic or oxo-anionic species at least during the initial phase of the reaction. On reduction, as may be produced by contact and treatment of the oxidized catalyst or catalyst precursor with hydrogen, or a hydrogen-containing gas, the catalytic metal, or metals component of the catalyst, is reduced to metallic metal, e.g., Co, and the catalyst thereby activated, and/or the catalytic activity increased. |
