Abstract:
A method for producing organic urea is provided that, by mixing and reacting liquid ammonia (NH 3 ) and gaseous carbon dioxide (CO 2 ) through the steps of ammonium carbamate formation ( 5 ), carbamate decomposition ( 7 ), urea synthesis ( 8 ) and evaporation ( 9 ) thereof, is carried out using organic ammonia from animal and plant biomass ( 2 ) and carbon dioxide recycled from the exhaust gases ( 6 ) from combined-cycle biogas boilers with plant biomass. The steps preceding the organic urea production include methanization ( 1 ), with a biomass “digester”, mixing with pig and chicken slurry and blood, pine needles and ash, and water, until obtaining: methane gas, air, gaseous ammonia and water vapor and PH regulator and catalyzing ( 3 ), where the obtained gases are condensed by cooling and the gaseous ammonia is separated to be stored at a pressure of 13 atmospheres. Organic urea and the chemical reactor AUS32 manufactured using from biomass are also detailed.

Claim (Index 1):
A method for producing organic urea that, made by mixing ammonia (NH3) and carbon dioxide (CO2) to form mixed components and reacting in, at least, two steps ( 5 ,  8 ), one step where the mixed components form ammonium carbamate, and another step where said ammonium carbamate is dehydrated in order to form urea, and is characterized in that it is carried out using biomass as a raw material and comprises the following prior steps:\n Methanization step ( 1 ), where in a biomass \u201cdigester\u201d ( 2 ) biomass and water, and it is externally heated until obtaining: methane gas, air, gaseous ammonia and water vapor; and Catalysis step: ( 3 ), where the mass of gases obtained in the previous step is condensed by cooling and the gaseous ammonia is separated to be stored at a pressure of 13 atmospheres.
