Development of a kinetic model for alcohol synthesis over a cesium-promoted copper/zinc oxide catalyst

摘要: This paper reports on a kinetic reaction network developed for the synthesis of oxygenates from gave over Cs-promoted Cu/ZnO catalysts in differential regime. The most important carbon- carbon bond forming reactions model are linear growth by addition an oxygenated C{sub 1} intermediate to alcohol chain that yields alcohols and {beta}-addition aldol condensation type mechanism between aldehydic n} 2-methyl-branched primary alcohols. carbon-oxygen is methoxide addition, {eta}{sub 0}, methyl esters. Estimates parameters show {beta} faster than growth, which results high selectivities branched alcohols, i.e., 2-methyl-1- propanol.
