摘要:
Disclosed is a catalyst system, its methods of preparation and its use for producing, alkenes and/or saturated or unsaturated oxygenates, which include at least one of an aldehyde and an acid (such as propyl aldehyde, acrolein, acrylic acid, isobutyl aldehyde, methacrolein, methacrylic acid), comprising subjecting the corresponding C3 to C5 aliphatic alcohols that are derivable from biomass, such as, propanols, propanediols, and isobutanol, to a vapor phase process over the catalytic system described herein in the presence of a gas mixture of oxygen, air or nitrogen and/or other suitable diluting gas. The catalyst system comprises a single catalytic zone or multi-catalytic zones, in each of which the composition of the co-feed and other reaction parameter can be independently controlled.
