Tungsten‐Based Catalysts for Selective Deoxygenation

Abstract

On the tip of the tung(sten): The title catalysts selectively perform deoxygenation of vegetable-oil-based feeds by either decarboxylation/decarbonylation or hydrodeoxygenation (HDO) pathways, depending on the dominant tungsten phase (WO3 and W2C). The process upgrades vegetable-oil-based feeds, under a hydrogen atmosphere, to high-value olefinic products, thus providing a significant advantage over other types of deoxygenation catalysts.
