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.
