Abstract
An apparatus and process for production of HCN from ammonia and a hydrocarbon gas by the use of microwave energy using a single mode microwave reactor.
Claims7
A product generator comprising:
- a microwave power source;
- a waveguide coupled to said power source for transmitting microwave radiation therethrough;
- said waveguide having a flared section;
- a resonant cavity attached to the flared section of said waveguide, said resonant cavity having a movable wall opposite the side of the cavity to which the waveguide is attached for tuning the resonant cavity and for focusing microwave radiation on a tubular reactor;
- a tubular reactor extending through said resonant cavity intermediate between the side of the cavity to which the waveguide is attached and the movable wall, in a direction parallel to the movable wall, said tubular reactor having inlet means for introducing gas and outlet means for removing product, the portion of the tubular reactor inside the resonant cavity being adapted to contain a catalyst.
