Description:

Operation of catalytic reformers requires injection of chloride compounds in order to regulate the performance of the reforming catalyst. Excess chlorides typically leave the process with the net hydrogen off-gas. Because water from the reduction of the reforming catalyst is also present, it is necessary to remove these chlorides from the off-gases of continuous regeneration catalytic reformers. Although activated aluminas have been used for chloride removal, they have certain disadvantages because of their potential to promote formation of organic chlorides, green oil and gum. These can lead to problems of corrosion, burner plugging, fouling or downstream catalyst poisoning. Zinc oxide based chloride guards generally eliminate these problems, but may also present problems with rapid pressure drop increase. Through a close cooperative effort between Japan Energy and Catalyst and Chemicals Inc., Far East, a member of the Süd-Chemie Group, a series of improved chloride guards has been developed. These new products and their commercial performance will be discussed in detail.
