Abstract
The reactor comprises a central perforated feed pipe for the i.c. engine exhaust gases closed at one end and wrapped round with successive layers of expanded metal having an active catalytic surface, the roll so formed being enclosed in an external envelope of elliptical cross section with a minor axis equal in length to the external diameter of the roll and a gas outlet pipe connected to a gas discharge and expansion space surrounding the roll, the ends of which are closed by circular partitions.
