Production of Acetaldehyde via Oxidative Dehydrogenation of Ethanol in a Chemical Looping Setup.

ABSTRACT: A novel chemical looping (CL) process was demonstrated to produce acetaldehyde (AA) via oxidative dehydrogenation (ODH) of ethanol. Here, the ODH of ethanol takes place in the absence of a gaseous oxygen stream; instead, oxygen is supplied from a metal oxide, an active support for an ODH catalyst. The support material reduces as the reaction takes place and needs to be regenerated in air in a separate step, resulting in a CL process. Here, strontium ferrite perovskite (SrFeO_3-δ) was used as the active support, with both silver and copper as the ODH catalysts. The performance of Ag/SrFeO_3-δ and Cu/SrFeO_3-δ was investigated in a packed bed reactor, operated at temperatures from 200 to 270 ^°C and a gas hourly space velocity of 9600 h^-1. T
