降低烟气污染物三效助剂LTA-1的开发与应用

分析了催化裂化再生烟气中SOx，NOx和CO对环境、装置等的影响；介绍了LTA-1助剂的作用机理、助剂研制以及实验室评价结果；重点介绍了该助剂在中国石化济南分公司Ⅰ套催化裂化装置上的应用情况。结果表明，首先按催化剂藏量的2．5％将助剂加入装置，然后每天按催化剂单耗的2．5％补入助剂，可使再生烟气中的SOx质量浓度平均降低67．4％；在不停加原来使用的铂基助燃剂的基础上，可使再生烟气中的NOx质量浓度平均降低40．4％；并且对产品分布和产品性质没有不利影响。

Development & commercial application of tri-functional additive LTA-1 for reducing FCC flue gas emission

The impacts of SOx, NOx and CO from regenerator flue gas on environment and FCC unit, etc are discussed. The working mechanism, preparation methods and laboratory results of LTA-1 additive, especially the results of commercial application in FCCU in SINOPEC Jinan Petrochemical Company are introduced. The results showed that when the first addition of additive was made at a dosage of 2.5% of catalyst inventory and followed by a make-up of 2.5 % of catalyst consumption each day, the SOx and NOx in flue gas were reduced by 67.4% and 40.4% respectively with addition of Pt-based combustion promoter. There is no negative impact on product qualities and product distribution.
