OP-2-15Cu-CONTAINING CATALYSTS FOR FATTY ACID TRYGLYCERIDSHYDROGENATION: RELATION OF CATALYTIC ACTIVITYTO THE MECHANISM OF COPPER REDUCTIONShtertser N.V., Khassin A.A., Minyukova T.P., Filonenko G.A.Boreskov Institute of Catalysis SB RAS, Novosibirsk, 630090, Russia,Pr. Lavrentieva, 5. E-mail: nat@catalysis.ruNovosibirsk State University, Novosibirsk, 630090, Russia, ul. Pirogova, 2Vegetable oils are a very promising source of fuel and various hydrocarbonproducts. Direct hydrogenation is one of prospective methods of vegetable oilprocessing because of its comparative technical simplicity and its possibility to obtainа wide variety of different products.In the present work we study relations between physicochemical properties ofcopper containing catalysts and their catalytic performance in hydrogenation of fattyacid triglycerides.The investigation was carried out using model catalysts which were thoroughlystudied earlier: copper hydrosilicate ((Cu,H) 2 [Si 2 O 5 ](OH) 4 chrysocolla) [1], copperchromite (CuCr 2 O 4 tetragonal distorted spinel) [2] and a solid solution of Cu 2+ in ZnO((Сu,Zn)O wurtzite-like structure) [3]. Our results allow to suppose that hydrogenationof triglycerides occurs by three main reactions: (1) triglyceride + H 2 ester of fattyacid and 1,2-propanediol + fatty acid; (2) triglyceride + H 2 diglyceride + fattyalcohol; (3) triglyceride + H 2 diglyceride + aldehyde. These steps are followed byhydrogenation of acids to alcohols and further – to hydrocarbons. Esterificationreactions result in C 18 -C 3 and C 18 -C 18 esters formation.(Сu,Zn)O catalyst was found to be the most effective of catalysts investigated inthe reaction of hydrogenolysis of ester groups in triglycerides; however its activity inthe hydrogenation of OH groups and double bonds was less than that of CuCr 2 O 4sample. (Cu,H) 2 [Si 2 O 5 ](OH) 4 catalyst was found to be less active in comparison tothe patterns of CuCr 2 O 4 and (Сu,Zn)O.The catalytic studies were analyzed together with our recent studies on structuralevolution and kinetics of reduction in hydrogen of the model catalysts. Copper ionsreduction of CuCr 2 O 4 and (Сu,Zn)O catalysts occurs without removal of lattice О 2–anion according to the reaction Cu 2+ + H 2 Cu 0 + 2H + abs. The generated protonsare absorbed by the oxide structure in the form of ОН - and НОН groups [2,3].(Cu,H) 2 [Si 2 O 5 ](OH) 4 catalyst reduction occurs according to traditional mechanism58
OP-2-15with water formation. Therefore, according to our data the most active catalysts in thereaction of direct oil hydrogenating are that demonstrating proton stabilization duringcopper reduction.References:[1]. T.M.
