NOVELTY - Producing renewable multi-purpose biomaterial for isolating hazardous contaminant from environment and storing energy, involves: dissociating biomass waste using anaerobic reaction to produce hydrocarbon and alcohol by applying waste heat recovered from external heat source; dissociating hydrocarbon and alcohol to generate carbon and hydrogen; harvesting carbon dioxide emitted from industrial process; reacting harvested carbon dioxide with hydrogen to generate hydrogen-dense fuel; and dissolving hazardous contaminant in hydrogen-dense fuel operating as solvent to generate liquid mixture.    USE - For producing a renewable multi-purpose biomaterial for isolating a hazardous contaminant from an environment and storing energy (claimed).    ADVANTAGE - The low specific energy H2 left over from the dissociation of the biomass produced hydrocarbon, alcohol, can be repurposed along with carbon donors (e.g. carbon dioxide and carbon monoxide) from industrial pollution to create hydrogen dense fuel with high specific energy hydrogen. In addition, the hydrogen dense fuel can be used as a solvent for dissolving dangerous contaminants to generate a liquid mixture, which is also a precursor to renewable fuel. By dissolving the contaminants in the H2-dense fuel, the harmful effects of the contaminants can be isolated from the environment and at the same time, the liquid mixture can be dissociated in an endothermic reaction to generate renewable fuel. The method allows the use of harmful contaminants that otherwise would be released to the environment, to be isolated to remove their harmful effects. The method readily accepts solutions of water and fuels including oxygenated constituents for purposes including reduced fuel production cost by avoiding the equipment and energy expenses required to produce and store water-free fuels. Also, reduce toxicity by reducing or eliminating the concentration gradient between water solutions within living cells and the fuel-water solution. Moreover, the method facilitates beneficial thermochemical regeneration production of more energetic and faster burning hydrogen-characterized fuels. Carbon for this purpose is delivered and donated by utilizing condensable liquid fuel constituents such as methanol as a process vehicle to safely and gainfully dispose of objectionable or waste substances such as grain dust, coal dust, polymer fumes, tire dust, diesel soot, paint fumes, cutting fluids, and cooking fumes.    DETAILED DESCRIPTION - Producing a renewable multi-purpose biomaterial for isolating a hazardous contaminant from an environment and storing energy, involves: dissociating biomass waste using an anaerobic reaction to produce at least one of hydrocarbon and alcohol by applying waste heat recovered from an external heat source; dissociating at least one of hydrocarbon and alcohol to generate carbon and hydrogen; harvesting carbon dioxide emitted from an industrial process; reacting the harvested carbon dioxide with the hydrogen to generate the hydrogen-dense fuel; and dissolving a hazardous contaminant in the hydrogen-dense fuel operating as a solvent to generate a liquid mixture that isolates the hazardous contaminant from the environment, where the hazardous contaminant comprises at least one of a carbon donor, a nitrogen donor and a hydrogen donor. An INDEPENDENT CLAIM is included for an energy-dense liquid mixture that reduces vapor pressure or availability of the vapor pressure of a previously hazardous contaminant, the liquid mixture produced by a method comprising: dissociating biomass waste using an aerobic reaction to produce at least one of hydrocarbon and alcohol by applying waste heat recovered from an external heat source; dissociating the hydrocarbon and alcohol to generate carbon and hydrogen; harvesting carbon dioxide emitted from an industrial process; reacting the harvested carbon dioxide with the hydrogen to generate the hydrogen-dense fuel; and dissolving a hazardous contaminant in the hydrogen-dense fuel operating as a solvent to generate the liquid mixture that isolates the hazardous contaminant from the environment, where the hazardous contaminant comprises at least one of a carbon donor and a hydrogen donor.
