CATALYTIC REACTOR/HEAT EXCHANGER

摘要

A catalytic reactor/heat exchange device (10) is provided for generating a catalytic reaction in a reaction fluid flow (12) and transferring heat to a cooling fluid flow (14). The device includes reaction flow channels (20) with turbulators (30) therein. The turbulators (30) include an initial portion (40) and a selected portion (34) that includes a catalytic layer or coating (36) to initiate the desired catalytic reaction a t a location (38) located downstream from the initial portion (40). In some preferred forms, each of the selected portions (34) of the turbulators (30) include at least one downstream section (103,120) wherein the heat transfer performance has been intentionally reduced to improve performance of the device (10) during start up conditions.
