CARBON DIOXIDE RECOVERY FROM BIOFUELS PROCESSES FOR THE PRODUCTION OF UREA

The present invention is generally directed to systems and methods for processing biomass for the production of biofuels, wherein carbon dioxide (CO2) produced as a by-product of such processing is reacted with ammonia (NH3) to produce urea (NH2)2CO, a common agricultural fertilizer. In some such em...

Beschreibung
Zusammenfassung:	The present invention is generally directed to systems and methods for processing biomass for the production of biofuels, wherein carbon dioxide (CO2) produced as a by-product of such processing is reacted with ammonia (NH3) to produce urea (NH2)2CO, a common agricultural fertilizer. In some such embodiments, the urea so produced can be used as fertilizer for biomass production, such biomass ultimately being channeled back into the systems/methods for conversion to biofuels.
