Lomonosov Moscow State Academy of Fine Chemical TechnologyThe present work relates to synthesis of catalytic systems based on alkoxide andacetylacetonoate precursors and investigation of its structure and activity in thereactions of alcohols and cellulose conversion into fuel oil components.Non-additive increase of W and Ta modified rhenium-contained catalytic systemsactivity has been found to occur in the reactions of bioalcohols conversion into olefinfraction. It was shown that when employing monometallic alkoxide based catalyststhe reaction selectivity cardinally changes that results in oxygenates formationinstead of olefins.Using XPS, XAFS and TPD (ammonia) methods genesis and acidic properties ofcatalytic systems were studied.The effective method of cellulose liquation in hydrogen donor medium was found.The characteristic feature of this process consists in direct deposition of Fe-Mo catalyston the cellulose surface. Such approach allows to one-step production of cellulosic oilfree from oxygen-containing compounds and increases hydrogen content in productswith elemental composition С = 85-89; Н = 7,1 – 7,9. First alkylcyclopentane andalkylcyclohexane were found in cellulosic oil formed with yield ~ 70 %.Fe-Mo catalytic systems genesis was characterized using Mossbauerspectroscopy. It was found that Fe state depends on precursor nature. When catalystwas formed from Fe acetylacetonoate and ammonium paramolybdate mixture, thewater-methanol solution of Fe complex undergoes partial destruction followed byformation of superparamagnetic clusters with nonstoichiometric oxide structure. Fe-Mobimetallic complex was not affected any failure after impregnation of the cellulosesurface. It’s important that both type of catalyst after treatment processes are in thesame state – ferric oxide superparamagnetic clusters and nonstoichiometric magnetite.Acknowledgements.
