Micro-reactor for carrying out chemical reactions e.g. in fuel cell and/or automobile technology

摘要

Educt and product streams are fed spirally or radially to and from a central reaction region of a micro-reactor. Thermal losses from the reaction region to the surroundings are minimized by feeding the educt and product streams in a spiral or radial manner in one or more planes to and from the reaction region which is located at the center of the micro-reactor. Chemical reactions are carried out in a micro-reactor by feeding one or more educt streams to a reaction region and feeding one or more product streams from the reaction region in countercurrent and in thermal contact with the educt stream(s). An Independent claim is also included for a micro-reactor for carrying out the above process, the micro-reactor (20) having feed channels (22) and return channels (23) arranged in a spiral or radial manner in one or more planes about a reaction region (21) at the center (30) of the micro-reactor.
