Abstract: An oxygen assisted Organosolv process for a more efficient delignification and producing bio-products by decomposing lignocellulosic materials comprises providing a lignin solvent with water, an acid, an oxidant and one or more lignin dissolving chemicals. The process also includes placing biomass in contact with oxidant, acid, water, the lignin solvent in any order or combined to form a recyclable solvent, and recycling at least a portion of the recyclable solvent by circulating the recyclable solvent back into contact with the biomass. The circulating of the recyclable solvent occurs for a period of time, during which, acid and oxidant may be added if necessary as they may be consumed by the process, after which, the process then includes separating material such as chemicals and lignin from the recyclable solvent.

Abstract: An organosolv process for producing bio-products by decomposing lignocellulosic materials comprises providing an initial lignin solvent with water, an acid, and a lignin dissolving chemical comprising at least one of an organic ester, butyl acetate, an organic furan, and furfural. The process also includes placing the lignin solvent in contact with a biomass to form a circulation solvent, and recycling at least a portion of the circulation solvent by circulating the circulation solvent back into contact with the biomass. The circulating of the circulation solvent occurs for a period of time, after which, the process then includes separating material such as chemicals and lignin from the circulation solvent. The chemicals can be recycled as new solvent or sold while lignin can be used as natural and renewable colorant for polymers such as poly lactic acid.

Abstract: An energy scavenging power system and method may include an energy conversion system having at least one transducer configured to harvest energy, an energy management and storage system configured to store harvested energy; and a load regulation system configured to provide stored energy to power one or more low power-consumption loads. The energy management and storage system may include a start-up capacitor having a small capacitance to allow for quick charging and fast turn-on, a short term capacitor to provide energy to the load or loads once turned-on, and a long term capacitor having a large capacitance to provide for sustained energy delivery to the loads. The system also may include a common charging bus that receives energy from each transducer, conditioned if necessary, and which then determines the capacitor to which the energy should be delivered.
