摘要/Abstract

摘要： 阐述了超低硫汽油的生产对现有FCC原料加氢预处理技术的影响以及世界各国的技术策略,并指明了FCC原料加氢预处理技术在生产超低硫汽油中的发展方向和主要技术措施。研究表明:从生产30μg/g的清洁汽油到生产硫含量小于10μg/g的超低硫汽油会造成FCC原料加氢预处理装置氢耗高、运转周期短、加氢预处理-催化裂化联合装置经济性差等问题。FCC原料加氢预处理生产超低硫汽油的主要技术措施有:优化现有的FCC原料加氢预处理装置、对现有FCC原料加氢预处理装置增加一个反应器、增加现有FCC原料加氢预处理装置的进料量、开发FCC原料加氢预处理-FCC组合工艺、新建或改造成缓和加氢裂化装置、新建或改造成部分转化加氢裂化、新建或改造FCC汽油后处理装置。

Abstract: The impacts of ultra low sulfur gasoline (ULSG) production on existing FCC feed hydrotreating units and major technical choices made by many countries were summarized.The development direction and main technical strategies of the FCC feed hydrotreating process for the production of ULSG were discussed.ULSG production which require sulfur content less than 10μg/g will significantly decrease FCC feed pre-treater unit cycle lengths and increase operating costs.Main technical strategies for FCC feed hydrotreating producing ULSG are:optimizing existing FCC feed hydrotreating device, increasing a FCC feed hydrotreating reactor, increasing feeding quantity of the existing FCC feed hydrotreating unit, developing FCC feed hydrotreating-FCC combination process, building new or converting into mild hydrocracking or partial conversion hydrocracking units, building new or modifying FCC gasoline post-treat unit.

Key words: FCC feed hydrotreating, ULSG, strategy
