0000 The invention of a process of producing biofuel using microorganisms and carbon dioxide extracted from industrial chimneys includes the separation and purification of carbon dioxide utilizing absorption and disposal towers and the use of solvents such as monoethanolamine. The purified CO<2 >is then injected into the cyanobacteria cultivation system in shallow pools with insulated walls and a glass or polycarbonate coating. Through aeration and mechanical stirring, photosynthesis and the growth of cyanobacteria, such as the Synechocystis sp. PCC 6803, is maximized. The cyanobacteria biomass is separated using centrifugation, dried, and ground. The lipids present in the biomass are extracted using solvents such as hexane or methanol under controlled conditions. The extracted lipids are then converted into biodiesel in a chemical reactor through a transesterification process with alcohol and a catalyst, while glycerol is collected as a by-product for use in the cosmetic and personal care industries.

0000 A modified dry grind method and system for biochemical and/or biofuel production, such as alcohol, in which dried grain (e.g., corn) feedstock is initially wetted prior to being milled to reduce the complexity and the amount of electricity typically consumed in the grain handling and milling part of a dry grind process. In one example, the method and system can include mixing a grain feedstock with a liquid in a holding tank to initially wet the grain. Then, the mixture can be subjected to a milling step in which the grain can be broken down, such as by a disc mill, into smaller ground pieces. Prior to being milled, the mixture of wet corn and liquid can be subjected to a dewatering device to remove liquid from the wet grain. Once milled, the milled grain can be further subjected to traditional, modified traditional, or non-traditional dry grind steps to produce biofuel and/or biochemicals.
