Method for carrying out in continuous, under so-called pseudo-isothermal
conditions and in a predetermined reaction environment, such as a
catalytic bed, a selected chemical reaction, comprising the steps of
providing in the reaction environment at least one heat exchanger fed
with a first flow of a heat exchange operating fluid at a respective
predetermined inlet temperature, the fluid passing through at least one
heat exchanger according to a respective inlet/outlet path, which method
also provides feeding into at least one heat exchanger and at one or more
intermediate positions of said path, a second flow of operating fluid
having a respective predetermined inlet temperature.
