Oil-containing biomass is a wide spread material for alternative fuel production in the form of biodiesel. However the production and usage of common biodiesel are connected with several problems, i.e. the dependence of fuel properties from source type and the necessity of additional modification to increase the quality of the product. These problems can be solved by the development of new technologies of triglycerides conversion into various compounds that are divided into two main processes: deoxygenation to produce diesel-like hydrocarbons and hydrogenation to form fatty alcohols which can be used both as highly effective fuel and feedstock of chemical production. In this work we studied the both stearic acid hydrodeoxygenation and hydrogenation processes in the presence of palladium catalysts on the base of hypercrosslinked polystyrene. Hydrotreatment processes were carried out in a stainless steel reactor-cell of Parr Series 5000 Multiple Reactor System. The analysis of liquid phase samples was performed using GC-2010 chromatograph and GCMS-QP2010S mass spectrometer (SHIMADZU, Japan). A comparison of catalytic activity was made by TOF value. It was found that HPS-based catalyst with Pd loading 1 (wt.)% seems to have the highest catalytic activity and selectivity regarding to the target products in both investigated reactions. It is noteworthy that the selected catalyst (1%-Pd/MN-270) remains its activity and selectivity regarding to the target product at the multiple usage up to 20 times.
