Abstract

In addition to catalytic tests, the addition of probe molecules (methanol, formaldehyde, ethylene glycol, ethanol, acetone, propionaldehyde) and thermoprogrammed-desorption studies (formaldehyde, acetaldehyde, ethanol, acetone) have been used to investigate the mechanism of higher alcohol synthesis on Cu-ZnO-Al2O3 catalysts. More attention is given to the first carbon-carbon bond and branched-product formation. An overall mechanism is proposed.
