摘要
RG系列保护剂级配体系在中海油惠州石化有限公司蜡油加氢裂化装置上成功进行了工业应用。一年以上的运行情况表明:RG系列保护剂级配在高酸、环烷基蜡油加氢裂化装置中能够很好地起到脱除杂质并容纳杂质的作用,有效延缓了保护剂床层压差、反应器总压差的上升;同时,RG系列保护剂级配还具有一定的精制活性,分担了一部分第二床层精制剂的脱硫、脱氮作用,具有原进口保护剂体系的相关功能。该级配体系可替代原进口保护剂,实现国产保护剂与进口主催化剂的组合应用。
The successful application of the RG series guard catalysts grading system in a high acid naphthenic VGO hydrocracking unit of CNOOC Huizhou Petrochemical Company Limited was introduced.The results of the operation for more than one year showed that the RG series guard catalyst system could remove and uptake the impurities,and effectively delay the rise of pressure difference of guard catalyst bed and total pressure difference of reactor.Besides,RG series catalysts exhibited certain refining activities,which shared a part of desulfurization and denitrogenation of the second fining catalyst bed and had a close function to the imported protective catalyst system.In summary,the industrial application results showed that the domestic grading guard catalyst could replace the imported protective agents,and be used with imported main catalysts of the hydrocracking unit.
