Title:
PRODUCTION AND USE OF CYANOGUANIDINE AND CYANAMIDE
Document Type and Number:
WIPO Patent Application WO/2012/123380
Kind Code:
A3
Abstract:
The present invention is concerned with a method of generating energy from water and a composition comprising cyanoguanidine, the method comprising (a) reacting the composition with water to form ammonia and (b) oxidizing the ammonia formed in step (a) to form water and nitrogen thereby generating energy or (b') converting the ammonia formed in step (a) into nitrogen and hydrogen; and oxidising the said hydrogen to form water thereby generating energy. Thus, cyanoguanidine can be used as a transportation fuel (e.g. for cars, trucks and marine vehicles). Particularly effective conversion of cyanoguanidine to ammonia can be achieved when step (a) occurs in the presence of a catalyst comprising vanadium and zinc, particularly when the vanadium is vanadium pentoxide and the zinc is metallic zinc. The ammonia can be combusted in internal combustion engine or an external combustion engine. The ammonia can also be oxidised in an ammonia fuel cell.
