REACTOR HAVING DUAL UPFLOW CATALYST BEDS

摘要

This invention provides a vertical catalytic reactor containing two catalyst beds located one above the other and connected in parallel flow arrangement. The effluent from the lower catalyst bed bypasses the adjacent upper bed, and the effluents from both beds are combined and pass out of the reactor at its upper end. A conical grid plate directing uniform fluid flow to the lower catalyst bed is supported principally on rigid thermal insulation in the lower head, and is restrained from upward movement by tension members. The lower grid assembly also supports the upper catalyst bed and its grid plate.
