A method for carrying out chemical reactions in so-called pseudo-isothermal conditions and in a predetermined reaction environment, for example a catalytic bed, comprises the step of arranging in the reaction environment at least one heat exchanger crossed by an operating fluid along a main direction.

Method for carrying out chemical reactions in pseudo-isothermal conditions

A method for in-situ modernization of a heterogeneous synthesis reactor, comprises the steps of providing an unperforated cylindrical wall () coaxial to the gas outlet wall () in a catalytic bed () of the radial or axial-radial type, the unperforated cylindrical wall () extending from an upper end () of the gas outlet wall () for a portion of the same of a prefixed length, so as to define a free-space () between the gas outlet wall () and the unperforated wall (), for the passage of a part of the gas leaving said catalytic bed (), and of providing means of closing the free-space () between the unperforated wall () and the gas outlet wall (), in proximity of the upper end () of the latter, preventing thereby a bypass of the catalytic bed or a recycling to the same of the gas entering respectively leaving the reactor. Thanks to the above steps, the present method allows to operate with a reduced amount of catalyst in the catalytic bed, keeping however the fluid dynamics and pressure drop characteristics unchanged.
