摘要
The system for reducing energy consumption in multi-unit reactors for heterogeneous synthesis, and more particularly for the synthesis of ammonia, with a single bed in each reaction unit, such as for example the "C.F. Braun". consisting of two cylindrical walls at least partly perforated for the annular delimitation of the catalytic beds; the outer wall (Fe) with diameter (Di) slightly smaller than diameter (Dc) of cartridge (C) has height (Hi), while (Hʹi) is the height of the internal cylindrical wall (Fi) which in turn has diameter (Dʹi) much smaller than said (Di) and about equal to diameter (Dt) of the central tube (T) for the outlet of reacted gas (RG). The top of internal cylindrical wall (Fi) is closed by a cover (CO) with distance (D) from the upper edge of the external wall of the basket (Fe), the basket being closed at the bottom by a tapered wall (PR). The catalytic bed is therefore: 1) annular with diameter (Di-Dʹi) for the whole of its height (Hi-D): 2) substantially a full cylinder along height (D): 3) tapered outside (for example a truncated cone), and internal cylindrical cavity with diameter (Di) for the whole of its height (H1 - Hi = Hiʺ). The reacted gas collects in the area (Q) inside the perforated cylindrical wall (Fi).
