Deoxygenation of palmitic and stearic acid over supported Pd catalysts: Effect of metal dispersion

---

Abstract.
Catalytic deoxygenation of palmitic and stearic acids mixture was studied over four synthesized Pd
catalysts supported on synthetic carbon (Sibunit) in a semibatch reactor and dodecane as a solvent at
260–300 8C. The catalysts were prepared by precipitation deposition method using Pd chlorides as metal
precursors. All catalysts contained 1 wt.% Pd, however, the metal dispersion was systematically varied.
An optimum metal dispersion giving the highest reaction rate was observed. The main liquid phase
products were n-heptadecane and n-pentadecane, which were formed in parallel. In addition to the
particle size effect the impact of mass transfer was elucidated and a detail discussion on temperature
programmed desorption of CO from the fresh and spent samples was provided.

Keywords: Deoxygenation, Fatty acid, Palladium.
