Resumo: | This work investigates the influence of several catalyst properties in the activity and selectivity of stearic acid deoxygenation reaction using molybdenum and tungsten carbides and nickel phosphide as catalysts. The studied catalyst properties were: active phase, nature of support, synthesis method and particle size. In addition, it was performed a review about the deactivation routes of carbides in liquid phase reactions. The experimental results showed that the active phase, nature of support, synthesis method and particle size influence the activity and/or selectivity of carbides and phosphides in the stearic acid deoxygenation reaction. Knowing the influence of each of those properties enable to steer the selectivity of this reaction to specific products. |
