STUDY OF Ni-CONTAINING SAPO-5 BY ESR SPECTROSCOPY AND HYDROGENOLYSIS OF THIOPHENE

摘要

ESR measurements and the thiophene hydrogenolysis have been car-ried out on the Ni-containing (7 wt.% Ni) SAPO-5 synthesized by introduction of NiO and Ni acetate in the reaction mixture and impregnation of SAPO with Ni nitrate. It has been shown that the Ni reducibility and dispersion and activity of samples in the thiophene hydrogenolysis are controlled by the Ni state intro-duced in SAPO-5.
