在不进行大规模装置改造的前提下 ,提出了提高喷雾浆液固含量和增强喷雾干燥能力等措施 ,使重油裂化催化剂的日产量由 2 0 0 0年的 30 2 8t提高到现在的 35 78t,成品收率也由 2 0 0 0年的 92 2 1 %提高到现在的 94 30 %。
Under the premise of no large-scale plant revamping, the measures to increase the solid content of spray slurry and enhance the spray drying ability are put forward. The daily output of heavy oil cracking catalyst is raised from 3028t in 2000 to 3578t now, The yield of finished products also increased from 92 2 1% in 2000 to 94 30% now.
