Abstract
When electrodes are inserted in a fluidized bed of conductive coke particles, an electric current can be passed with sufficient power to raise the bed to a high temperature. This device becomes a chemical reactor when the fluidizing gas is appropriately chosen. The reaction conditions which obtain in such a reactor are sometimes of especial value in producing favorable yields in chemical reactions.The design and operating characteristics of laboratory scale units are described. These are usually Vycor tubes fitted with rubber stoppers through which electrical and gas connections are made. Even with such simple apparatus, it is possible to operate at 1500°C.Several chemical reactions have been studied in detail using reactors of this type. Among these are some which show commercial promise, such as the high temperature reaction of ammonia and hydrocarbons to form hydrogen cyanide.
