Abstract
A reactor for heterogeneous synthesis with reduced energy consumption. The reactor includes two cylindrical walls that are at least partly perforated and which annularly deliminate the catalytic beds. An outer wall (Fe) has height (Hi) and a diameter (Di) that is slightly smaller than diameter (Dc) of cartridge (C). An internal, cylindrical wall (Fi) has a height (H'i) and a diameter (D'i) much smaller than diameter (Di). The diameter (D'i) is about equal to diameter (Dt) of a central tube (T) which is an outlet for reacted gas (RG). The top of the cylindrical wall (Fi) is closed by a cover (CO) and is located at a distance (D) from the upper edge of the external wall of the basket (Fe). The basket is closed at its bottom by a tapered wall (PR). The catalytic bed is therefore shaped in three distinct arrangements: first, an annular shaped portion having a diameter (Di-D'i) for the height (Hi-D); second, a substantially full cylinder portion along height (D); and third, a portion having a tapered outside shape and an internal cylindrical shaped cavity, this portion having a widest diameter (Di) and height (Hl-Hi=Hi"). Reacted gas collects in an area (Q) inside perforated cylindrical…
