A review on glycerol valorization to acrolein over solid acid catalysts

The projected rise in global biodiesel production and demands inevitably implied a linear rise in glycerol production. The paper therefore critically tailored recent literature on the progress made regarding the glycerol to acrolein process. Emphasis was given to the role of catalysts such as oxides, heteropoly acids, zeolites and silicoalumino phosphates (SAPOs) and their associated activity and stability properties. Concise details on the reaction mechanisms and the strategies being employed to ensure optimal catalytic performance, hinder deactivation and improve product yields were also appropriately captured and analyzed. An outlook was simultaneously tailored to identify new paths for future research. (C) 2016 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
