The palladium-containing catalysts on the base of hypercrosslinked polystyrene in the Green-diesel production process
Abstract
New palladium-containing catalysts on the base of hypercrosslinked polystyrene (HPS) were studied in the hydrodeoxygenation (HDO) reaction of stearic acid as model compound. The physics-chemical and kinetics investigation of synthesized catalytic systems in the comparison of industrial catalysts on the base of activated carbon was conducted. The structure of palladium-containing catalysts on the base of HPS was explored by the methods of low-temperature nitrogen physical adsorption, X-ray photoelectron spectroscopy, IR-Furies spectrometry and thermogravimetric analysis. Kinetic investigations
were carried out with continuous stirring (700 rpm), using dodecane as solvent, under the hydrogen pressure 0,6 МPа. The influence of temperature (230–255 °С) and initial stearic acid concentration (0,05–0,20 mol/l) on the HDO process was studied. It was found that that the system 1%-Pd/HPS is the most active (W20 % = 0,013 molSA/(molPd·min)) and selective (Sн–С17 = 99 %) in
the stearic acid hydrodeoxygenation process among the studied catalysts. The estimation of influence of temperature and initial substrate concentration revealed that the process rate increases with increasing of temperature, and the increase of the initial stearic cid concentration leads the increasing the GDO duration. The use of palladium catalysts based on HPS can improve the efficiency of GDO, and the present research forms the basis for modification of Greendiesel production technology.
