The samples were collected from a Chinese refinery.The sodium hydroxide（Na OH）reagent is of analytical grade.The sample was crushed，screened，and ground to less than150μm.The main element contents were measured by an atomic absorption spectrophotometer（Hitachi AAS-180/80）and a carbon/sulfur analyzer（LECO CS-600）.The compositions of valuable metals in spent petrochemical catalyst are listed in Table 1.The main phases are retgersite，2-deoxystreptamine，silicon oxide，vanadium oxide，zinc sulfide，aluminum oxide，and molybdenum oxide according to the X-ray diffraction analysis（PANalytical X’Pert PRO）shown in Fig.1.
