Abstract: Most reforming devices at home and abroad adopt granular activated clay to remove olefins in reforming generation oil.However，frequent renewal of granular activated clay is not conducive to the production safety，and abandoned clay pollutes the environment，which is also expensive to deal with，leading to a higher comprehensive operating cost.According to the shortcomings of granular activated clay，a new type of the non-hydrogenation refining catalyst TCDTO-1 for reforming generation oil was developed to replace activated clay which had longer one-way life and can be regenerated repeatedly.A bypass experiment facility for removing the trace olefins in reforming generation oil was designed.Experiment results showed that TCDTO-1 catalyst had excellent activity and stability，and the one-way life of which was 7 times of the industrial activated clay，so it had an industrial application value.
