Abstract
In order to solve the diffusion,reaction and deposition problems of high molecular materials such as asphaltenes and resins,and to improve the catalyst’s activity and metal capacity during the process of residue hydrodemetallization,we developed a series of key technologies and 4 grades residue hydrodemetallization catalysts(PHR-101,PHR-102,PHR-103,PHR-104)by optimized catalyst design. Non-acidic binder was employed to replace the traditional acids to prepare alumina support with substantially increased pore volume and size. Dual-peak-pore-structure support,with 16.4% pore size above 1000nm,was obtained through compound pore expanding method to improve catalysts’ pore structure. And non-uniform distribution of active metal components was achieved to promote impurities to diffuse to and deposit on internal catalyst whose active-site distribution was refined. The results of a 2000h test on small-scale device showed that catalysts’ activity and stability after removing the impurities(metal,sulfur,carbon residue)were significantly higher than that of conventional catalysts. A 1L-scale Pilot test,with 5500h long period running under the industrial operating conditions and products requirements,indicated that the prospective running life of catalysts reached more than 8000h which totally satisfied the industrial application requirement. A 14 months industrial hanging-basket test was carried out and the results showed that,compared with the commercial atalysts,the developed catalysts exhibited higher metal capacity and more uniform metal deposition.关键词
