20120020847 | Retention Of Solid Powder Catalyst By In-Situ Cross Flow Filtration In Continuous Stirred Reactors - A system for the retention of finely divided solid catalysts inside a continuously stirred back-mixed reactor is presented. The system includes multiple porous media filter elements and multiple reactor baffles. The porous media filter elements are located to act as part of said reactor baffles. The porous media is selected to retain the large majority of the catalyst particles while allowing the reacted contents to leave the reactor through the pores of the porous media. The porous media elements may have a circular cross-section. The system utilizes the pumped flow of the reactor's agitator system to sweep solids from the porous media, and a high velocity zone is created around the back side of the porous media filter elements by a venturi effect caused by design and placement of the baffles and the porous media elements. | 01-26-2012 |
20110217415 | Hybrid fermentation process - A hybrid fermentation process for the production of; fermentation products is provided. This process includes combining a saccharide-rich slurry. This saccharide-rich slurry may include, but is not limited to starch, cellulose, hemi-cellulose, cellulobios, and may or may not contain, proteins, peptides, amino acids, lignin and to other biologically produced or environmental compounds. The process also includes a fermenting organism such as yeast, bacteria, archea, algae or other biocatalyst. The process also includes nutrients for the fermenting organism in a continuous fermentation step, thereby producing a partially fermented stream. The process also includes introducing the partially fermented product stream into a batch fermentation step, thereby producing a finished fermented beer stream. | 09-08-2011 |
