A gas-solid phase exothermic catalytic reactor with little temperature difference is disclosed which is principally comprised of a shell (P), a partition (H), cold-tube internals (Cb), a holder (S) and a porous plate (R). The reactor is divided into two sections, an upper chamber and a lower gas chamber, by the partition (H), and the lower reaction chamber is filled with catalyst layer (K). The end-holder (S) supports the cold-tube internals (Cb), and the end-porous plate holds the catalyst layer outside of the cold-tube internals. The gas-feed-in tube (a) of the cold-tube internals passes the partition (H) and is sealed with the removable stuffing box. The cold gases in the cold-tube internals exchange heat with the reaction gas in the catalyst layer outside the cold-tube internals in counter current. The reactor has advantages as little temperature difference across the catalyst layer, high catalyst activity, simple and reliable structure, good operating performance and low cost. <IMAGE> |
