Method for modernization of a heterogeneous synthesis reactor

摘要

A method for "in-situ" modernization of a heterogeneous exothermic synthesis reactor (1), comprising the step of arranging at least a first catalytic bed (18) in an upper portion (2a) of the reactor (1), is distinguished by the fact of further providing a plurality of catalytic beds (20-22) arranged in a lower portion (2b) of the reactor (1) in parallel with one another, and by the fact of loading said catalytic beds (20-22) in the lower portion (2b) of the reactor (1) with a catalyst having a greater activity than that of the catalyst loaded into the first catalytic bed (18). Thanks to the above steps, the present method allows obtaining a reactor (1) having a high conversion yield and production capacity. A preferred catalyst having a greater activity is of the type based on graphite-supported ruthenium. <IMAGE>
