Catalysis on Nano-ozide with Nano-zeolite
1.Introduction As the demand of the lighter oils, middle distillates and gasoline is increasing in the oil products, the technology should be more developed for heavy oil upgrading or conversion to lighter oils. Among the refinery processes for the heavy oils to lighter oils, RFCC (Resid Fluid Catalytic Cracking) is more attractive as a carbon-and-hydrogen balanced technology than carbon rejection technology by thermal cracking without catalysts or hydrogen addition technology by catalytic hydroeracking (HC). The performance of RFCC which increases the yield of lighter oils adjusting to the demand depends on the catalysts developed. Porous matrix as a pre-aetive zone is usually required for the RFCC catalyst because either higher carbon residue (CCR) or a large amount of metals (V+Ni) usually contained in the heavy oils is pretreated in the zone before cracking on the zeolite. The well-controlled nano-pore structure has been studied to be consisting of well-designed zeolite and matrix made of llano-oxide1,2,3. The nano-pore structure of zeolite and matrix shown in Fig. 1 was studied on a base of RFCC catalyst.
