Optimization of unsupported CoMo catalysts for decarboxylation of oleic acid

Hydrodeoxygenation (HDO) processes have been developed to remove the oxygenated compounds in lipids. However, the HDO process consumes excess hydrogen. As opposed to the HDO process, decarboxylation does not require hydrogen. In this study, decarboxylation of oleic acid without hydrogen was carried out over unsupported CoMo catalysts. Unsupported CoMo catalysts were prepared by a co-precipitation method. The Co/Mo ratio was systematically varied to optimize unsupported CoMo catalyst. The catalyst properties were studied using various characterization techniques and related to the activity results in decarboxylation. (C) 2015 Elsevier B.V. All rights reserved.
