Abstract:
A modular device suitable for conducting at least one chemical reaction in the presence of a catalyst, said device comprising in combination:at least one reaction zone where the chemical reaction is carried out, whereby said zone comprises a chamber (11) where a catalyst bed that comprises catalyst (22) is located,means (21) for introducing at least one liquid fluid F.sub.1 that comprises at least one reagent, whereby said means are located approximately in the center of said chamber (11), with the fluid being introduced without contact with the catalyst,one or more sections (18) for passage of a second fluid F.sub.2 that comprises reagents and the products that come from the catalyst, whereby said fluid is liquid,one or more sections (17) for passage that allows the circulation of at least a third fluid F.sub.3 that is gaseous,said sections (17, 18) for passage are dedicated to the passage of a fluid,at least one of said sections (17) for passage comprises at least one wall (11a) common with at least one of said sections (18) for passage, and at least one wall that is formed by a inner wall of a reactive distillation device or an auxiliary element, and at least one of said sections (18) comprising a second wall (11b)said sections (17, 18) for passage are longitudinally coaxial with at least a portion of the periphery of said chamber (11),and a horizontal plate (33) proximate the lower edges of said walls (11a) and (11b), the lower edge of said wall (11a) being closer to said plate 33 than the lower edge of said wall (11b).
