Abstract
Described here is a system (8; 9; 50) of walls for catalytic beds of reactors (1) for the heterogeneous synthesis of chemical compounds characterized in that it comprises a wall (14) of predetermined thickness in direct contact with a catalytic bed (7) for containing it, said wall having a plurality of portions (17) permeable to gases and a plurality of portions (19; 54; 55) impermeable to gases, said portions (17) permeable to gases each being equipped with a plurality of slits (18; 52, 53; 60; 70) of a size such as to allow the free passage of the synthesis gases through them but not the passage of the catalyst.
Claims9
A reactor for the heterogeneous synthesis of chemical compounds, comprising:
- a shell closed at the opposite ends by respective bottoms;
- an opening for the inlet of synthesis gas;
- an opening for the outlet of the reaction products;
- and
- at least one catalytic bed having a gas inlet side or bottom and a gas outlet side or bottom, said at least one catalytic bed being delimited at least one of said gas inlet side/bottom or gas outlet side/bottom by at least one system of walls for said at least one catalytic bed,
- wherein said at least one system of walls comprises a containment wall in direct contact with said catalytic bed for containing it,
- said wall having a plurality of portions permeable to gases and a plurality of portions impermeable to gases,
- said portions permeable to gases each being equipped with a plurality of slits of a size such as to allow the free passage of the synthesis gases through them but not the passage of the catalyst,
- said portions impermeable to gases constituting a mechanical support for said catalytic bed, and
- a distribution wall equipped with gas-permeable portions arranged in spaced relationship with said containment wall so as to create an interspace with it.
