The effect of H 4 SiW 12 O 40 loading on the catalytic performance of the reduced Ni–H 4 SiW 12 O 40 /SiO 2 catalysts for hydrocracking of n-decane with or without the presence of thiophene and pyridine is studied. The catalysts were characterized by BET, XRD, Raman, XPS, H 2 -TPR, H 2 -TPD, NH 3 -TPD and FT-IR of pyridine...
A new method to remove and purify the naphthenic acids in heavy fractions of petroleum is studied in this paper. An ammonia solution of ethylene glycol was used as the acid removal reagent by mixing with the petroleum fraction and then allowing the two phases to separate, with the naphthenic acids being extracted from petroleum fractions. The naphthenic acids were recovered by heating the ammonia...
