摘要: Alkali oxides added to methanol catalysts increase the formation of ethanol, n-propanol and isobutyl alcohol. This result has been known for many years, yet few quantitative studies have reported in literature. Data obtained on a commercial copper-zinc oxide catalyst promoted with K2 CO3 are presented compared published work. The optimum promoter concentration was about 0.5% by weight. H2 CO feed ratio important determining higher alcohol selectivity. rate production varied as pp while methanol, ethanol both exponents were positive less than 1.6. Decreasing hydrogen carbon monoxide from 2 0.5 more doubled Chain growth schemes predicting selectivity estimates parameters given. L'addition d'oxydes alcalins aux catalyseurs de la du augmente d'ethanol, et d'alcool isobutylique; ce resultat est connu depuis nombre d'annees, mais jusqu'ici peu d'etudes quantitatives sur point ont paru dans litterature. On rapporte les resultats d'une etude faite un catalyseur forme cuivre d'oxyde zinc active par CO3; compare aussi obtenus avec ceux La optimale l'activateur en poids. Le rapport d'alimentation H2/CO pour selectivite alcools superieurs. vitesse l'alcool isobutylique varie comme pp, tandis que, le cas l'ethanol propanol normal, deux exposants etaient positifs inferieurs En diminuant 0.5, double alcool isobutylique. presente des modeles croissance chaǐnes prevoir superieurs donne estimations differents parametres.
