Abstract

Palladium catalysts with different loading on SBA-15 have been prepared using a direct synthesis method and characterized with X-ray diffraction, micrograph images, and X-ray photoelectron spectroscopy. Mesoporous Pd-SBA-15 was an active and selective catalyst for deoxygenation of stearic acid in dodecane as a solvent at 300 °C under 17 bar of 5 vol% H2 in argon as a carrier gas in a semibatch reactor.

Palladium/SBA-15 catalysts have been prepared using a direct synthesis method and characterized with X-ray diffraction, micrograph images, and X-ray photoelectron spectroscopy. They were an active and selective catalyst for deoxygenation of stearic acid in dodecane as a solvent at 300 °C under 17 bar of 5 vol% H2 in argon as a carrier gas in a semibatch reactor.
