Abstract
A process for providing an ammonia feed includes (i) a thermal gasification stage and (ii) a controlled catalyzed hydrolysis stage. In stage (i) urea, water and heated gases are introduced into a gasification chamber upstream at a temperature and for a time sufficient to gasify the solution to a first stage gas stream comprising ammonia and isocyanic acid. The first stage gas stream is introduced to a stage (ii) catalytic hydrolysis reactor wherein the isocyanic acid) is hydrolyzed to ammonia with carbon dioxide as a byproduct. The process is provides ammonia for a low-temperature operation as needed.
