System for reducing energy consumption improving reactors for heterogeneous catalytic synthesis and relative reactors

, : System for reducing energy consumption improving reactors for heterogeneous catalytic synthesis and relative reactors. United States Patent (US 4,904,453): 11 pp.

A method is provided for substantially reducing the energy consumption of conventional reactors for heterogeneous synthesis such as for ammonia and methanol synthesis. The method comprises inserting, in at least one catalyst bed, two concentric cylindrical substantially perforated walls to laterally delimit the bed, a bottom closure between these walls, and optionally a diaphragm on top of the bed. Optionally also, a catalyst granulometry gradient may be employed in the upper part of the bed.
