Abstract
A modular system and method for producing urea from bio-mass includes means and steps for “homogenizing” a biomass feedstock stream having components with different bulk density BTU content into a stream having a consistent bulk density BTU content. The steps include cleaning the incoming bio-mass feedstock stream to remove non-organic matter, blending the cleaned bio-mass feedstock stream to obtain a homogeneous blend having a consistent bulk density BTU content, and milling the homogeneous blend bio-mass feedstock stream to a predetermined size no greater than 12 mm.
Claims20
A method for producing urea from bio-mass, the method comprising the steps of:
- cleaning a bio-mass feedstock to remove substantially all non-organic matter;
- blending the cleaned bio-mass feedstock to obtain a substantially homogeneous blend;
- pelletizing the blended bio-mass feedstock to a substantially uniform size;
- gasifying the pellets in a gasifier;
- and
- combining a resultant CO2 stream from the gasifier with NH3 to form urea.
