Abstract

A process for synthesizing material uses an exothermic reactor which comprises a coolant shell, two concentric pipes provided within the shell, a catalyst bed packed between inner and outer ones of the concentric pipes, an introduction tube connected to the inner pipe through which a starting fluid is introduced, and a communication path enabling the fluid after the passage of the inner pipe to be passed through the catalyst bed in a direction opposite to the direction of the passage through the inner pipe, the coolant shell having an inlet and an outlet for a coolant arranged in such a way that the flow of the coolant is parallel to the flow of the fluid within the catalyst bed. The coolant on the outside and the starting fluid on the inside of the catalyst bed cools the bed in such a way as to produce a temperature distribution along the bed that follows a maximum reaction rate line (M in FIG. 1) relating the concentration of the methanol to the temperature of the starting fluid.
