Apparatus and process suitable for producing hydrogen

摘要

Apparatus suitable for producing hydrogen comprising a housing containing (i) a convection section having inlet- and outlet means for a heating medium (e.g. combustion gas), and (ii) a reaction section having inlet- and outlet means for process fluid, which reaction section comprises (a) catalyst container(s) extending into the convection section and comprising a plurality of helically wound open-ended tubes wherein the process fluid (e.g. steam and methane) inlet means are in communication with the catalyst container(s) and wherein the process fluid outlet means are in communication with the upper end parts of the tubes.
