Abstract
A process is presented for the removal of acetaldehyde from mixture of oxygenates. Acetaldehyde is selectively removed in the presence of other oxygenates like ketones, alcohols and nitriles using an amorphous sodium doped alumina derived from thermally decomposed Dawsonite. The process successfully removes acetaldehyde which can adversely impact catalyst operation.
