Abstract

A chemical reactor for catalytic reactions, comprises a substantially cylindrical shell ( 2 ) closed at the opposite ends by respective covers ( 3 and 4 ), at least one reaction zone ( 7, 8 ) in which a respective catalytic bed ( 9, 10 ) and a plurality of heat exchangers ( 25 ) placed in said at least one reaction zone ( 7, 8 ) are supported.

Claims (5)

1. A method for carrying out catalytic chemical reactions, comprising the steps of:

feeding reactants to at least one reaction zone of a chemical reactor comprising at least two reaction zones each supporting a respective catalytic bed and a plurality of heat exchangers placed in said catalytic bed, said heat exchangers being grouped into at least two structurally independent heat exchange units; and

feeding respective different operating heat exchange fluids to said heat exchange units for controlling the reaction temperature under pseudo-isothermal conditions,

wherein said different operating heat exchange fluids are fed to the heat exchange units in said reaction zones, respectively, so that the heat exchange units of a first catalytic bed are fed in parallel by a first operating heat exchange fluid while the heat exchange units of a second catalytic bed are connected in series and flown one after the other by a second operating heat exchange fluid.

2. The method according to claim 1 , wherein said different operating heat exchange fluids are chosen among the group comprising: reactant gases, water, boiling water or melted salts.
