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.

1-20. (canceled)
A method of preparing a bio-mass feedstock for use in a gasifier, the method comprising the steps of:
- (i) cleaning a bio-mass feedstock stream to remove non-organic matter, the bio-mass feedstock stream including a feedstock component having a different bulk density BTU content than at least one other feedstock component, the cleaned bio-mass feedstock stream including no more than 1% foreign matter by weight;
- (ii) blending the cleaned bio-mass feedstock stream to obtain a homogeneous blend having a consistent bulk density BTU content;
- (iii) milling the homogeneous blend bio-mass feedstock stream to a predetermined size no greater than 12 mm.
A method according to claim 23 wherein the constant temperature is held within a range of ±25° C.
A system of preparing a bio-mass feedstock for use in a gasifier, the system comprising:
- (i) means for cleaning a bio-mass feedstock stream to remove-non-organic matter, the bio-mass feedstock stream including a feedstock component having a different bulk density BTU content than at least one other feedstock component of the stream, the cleaned bio-mass feedstock stream including no more than 1% foreign matter by weight;
- (ii) means for blending the cleaned bio-mass feedstock stream to obtain a homogeneous blend having a consistent bulk density BTU content;
- (iii) means for milling the homogeneous blend bio-mass feedstock stream to a predetermined size no greater than 12 mm.
