Реферат: Characterization data showed that after metal introduction the structure of H-Y-5.1 zeolite was retained even if, the specific surface area decreased by more than 40%. Fe introduction led to a decrease of strong acid sites while Ni elevated weak and medium Lewis acid sites. The metal particle size of Fe and Ni was ca 5 nm and 19 nm, respectively. Interactions between metals were confirmed by TEM and TPR measurements. Catalytic results revealed low activity of IE HDO with the monometallic Fe catalyst and high cracking activity of the solvent in the presence of Ni catalyst. For 5-5 wt% bimetallic Fe-Ni catalyst only desired oxygen-free cyclic products were detected after 4 h.
