【摘要】 文章总结了近五年国内三套典型食品级二氧化碳装置脱烃催化剂的最新运行情况。三套装置均采用杭州快凯高效节能新科技有限公司和华烁科技股份有限公司联合开发的食品级二氧化碳全套工艺包，以及华烁科技股份有限公司的专利产品THC-2型脱烃催化剂。脱烃装置稳定运行的结果表明，在操作温度为360～400℃时，脱烃塔出口总烃含量<20×10^-6，苯含量<10×10^-9，满足食品级二氧化碳的质量指标要求。此外，催化剂操作弹性大、稳定性好，部分装置的催化剂运行寿命已超过4 a且仍能正常使用。更多还原

【Abstract】 Latest operational data of dehydrocarbon catalysts for three typical domestic food-grade carbon dioxide units over the past five years are summarized. The integrated food-grade CO₂ process package co-developed by Hangzhou Kuaikai Hi-Tech Co., Ltd. and Haiso Technology Co., Ltd., as well as the THC-2 dehydrocarbon catalyst patented by Haiso Technology Co., Ltd., is both adopted. The stable results of dehyrocarbon units demonstrate that the total hydrocarbon content below 20×10^-6 and benzene level below 10×10^-9 at the outlet of the dehydrocarbonization tower under 360-400 ℃ operating temperatures, can meet the quality specifications for food-grade carbon dioxide totally. Furthermore, the catalyst exhibits a wide operating window and excellent stability. In some units, the catalyst life has exceeded four years while maintaining normal operational performance.更多还原
