Patent CA-2192534-A1 (CA)
Title: Process and apparatus for gas phase exothermic reactions
Inventor: RATNANI KEBIR
IPC: F23G7/06
Filed: 1996-12-10
Abstract: The gas phase exothermic reaction of a feed gas mixture  is carried out by providing  first  and second chambers in fluid communication with one another and each containing a bed of solid heat exchange material and at least one bed of catalyst material,  each chamber being selectively operable in cooling and heating modes.  The feed gas mixture is introduced into a selected one of the chambers when the selected chamber is in the cooling mode and the other chamber is in the heating mode so that the feed gas mixture  flowing through the  selected chamber contacts  the  bed  of  heat  exchange  material  before contacting the bed of catalyst material,  the  feed gas mixture being  reacted  in the  catalyst  bed  to  form a gaseous product.  The gaseous product is conducted from the selected chamber to the other chamber so that the gaseous  product  flowing  through  the  other  chamber contacts the bed of catalyst material before contacting the bed of heat exchange material. The direction of gas flow through the  chambers  is periodically reversed so that the first and second chambers alternately operate in the cooling and heating modes,  thereby forming between the first and second chambers a hot zone containing the gaseous products. A portion of the gaseous product is discharged from the hot zone so as to withdraw sufficient heat to maintain the reaction in the catalyst bed of the selected chamber at a temperature below a predetermined maximum temperature, while maintaining autothermicity.
