Abstract:
1. A radial chemical reactor for catalytic reaction comprising: a substantially cylindrical shell, closed at opposite ends by respective covers; a first catalytic bed with a substantially ring-shaped cross-section, coaxially supported in said shell and having a reagent gases inlet side and a reaction mixture outlet side; a plurality of heat exchangers supported and distributed in a substantially ring-shaped respective portion of said first catalytic bed, an operating heat exchange fluid flowing in said heat exchangers; at least one second catalytic bed with a substantially ring-shaped cross-section, supported in said shell co-axially to said first bed and at a predetermined distance from said first bed, said second catalytic bed having a reaction mixture inlet side and a reaction gaseous products outlet side; a plurality of heat exchangers supported and distributed in a substantially ring-shaped respective portion of said second catalytic bed, said operating heat exchange fluid flowing in said heat exchangers; means for distributing the reagent gases over all said inlet side of said first catalytic bed; means for putting in fluid communication the outlet side of said first catalytic bed with the inlet side of said second catalytic bed; and means for distributing the reaction mixture over all said inlet side of said second catalytic bed, wherein said plurality of heat exchangers of said first catalytic bed extend in a portion of the first catalytic bed from the outlet side of the catalytic bed itself, and wherein said plurality of heat exchangers of said second catalytic bed extend in a portion of the second catalytic bed from the inlet side of the catalytic bed itself.
