Abstract
A microwave hydrolysis reactor for converting urea into ammonia has one or more reaction chambers into which a urea solution is fed via a feed device and a discharge device for discharging an ammonia-water mixture. A catalytic converter is arranged in the reaction chamber. A microwave-transmitting device allows irradiating so that energy is fed to the urea solution in the reaction chamber.
Claims5
A process for converting urea into ammonia, which comprises:
- feeding an aqueous urea solution to a reaction chamber;
- flowing the aqueous urea solution through a catalytic converter in the reaction chamber and thereby catalytically converting urea into ammonia;
- introducing energy into the reaction chamber by irradiating with microwaves;
- and
- discharging an ammonia-water mixture formed in the reaction chamber from the reaction chamber.
