重整生成油选择性加氢脱烯烃技术应用论文

　　

摘 要：连续重整装置反应产物中的溴指数较高，会降低产品的稳定性，影响产品质量，通常采用白土脱烯烃，白土更换频繁，人员劳动强度大。本文通过从重整生成油烯烃组成及加氢脱烯烃反应原理两方面对加氢脱烯烃装置进行了分析，重整生成油烯烃主要以C5和C6烯烃为主；重整生成油加氢脱烯烃反应主要分为：烯烃加氢、加氢裂化和芳烃加氢反应。加氢脱烯烃催化剂可以对烯烃进行选择性加氢，抑制加氢裂化和芳烃加氢反应发生。通过采用重整生成油选择性加氢脱烯烃HER技术，溴指数脱除率97%以上，产品溴指数大幅降低，苯、甲苯溴指数＜5mgBr/100g，提高产品质量同时替代原白土脱烯烃的工艺，满足产品质量升级需求。

Abstract: The bromine index in the reaction products of the CCR is relatively high, which can reduce the stability of the product and affect its quality. Therefore, white clay is usually used for olefin removal, and the replacement of white clay is frequent, resulting in high labor intensity for personnel. This article analyzes the hydrogenation olefin removal unit from two aspects: the composition of oil olefins generated by reforming and the principle of hydrogenation olefin removal reaction. The oil olefins generated by reforming are mainly C5 and C6 olefins; The hydrogenation and dealkylation reactions of reformed oil mainly include olefin hydrogenation, hydrocracking, and aromatic hydrocarbon hydrogenation reactions. Hydroolefin removal catalysts can selectively hydrogenate olefins, inhibiting the occurrence of hydrocracking and aromatic hydrocarbon hydrogenation reactions. By adopting the HER technology for selective hydrogenation and olefin removal of reformed oil, the bromine index removal rate is over 97%, and the bromine index of the product is significantly reduced. The bromine index of benzene and toluene is less than 5mgBr/100g, which improves product quality and replaces the original clay de olefin process, meeting the demand for product quality upgrading.
