Stearic acid hydrodeoxygenation into n-heptadecane on the
catalyst containing Pd nanoparticles incorporated in the
hypercrosslinked polystyrene matrix was studied. The used catalysts were
characterized using TEM, CO chemisorption, low-temperature nitrogen
physisorption and XPS. A clear hydrogen pressure dependent induction
period was noticed. Kinetic regularities were studied for the indicated
reaction in the presence of polymer based catalysts. A mathematical
model for decarboxylation was suggested which was able to adequately
describe experimental data at different temperatures, hydrogen pressures
and initial concentrations of stearic acid. Kinetic constants were
calculated and their statistical analysis was performed.
