Abstract:
A method of creating a multi-phase fuel wherein said fuel comprises a gas, a solid, a liquid solvent phase and an aqueous phase from animal waste comprising the combination of the animal waste, a solvent, and a water/alcohol solution into a fluid mixture, placing the mixture into a closed reactor, heating said reactor between about 245° C. and 385° C. for between about 5 and 70 minutes and cooling said resulting multi-phase fuel. The animal waste may be manure, mortalities, municipal waste, or chicken litter. The preferred solvent is petroleum with the preferred petroleum being diesel fuel. The final multi-phase fuel can be separated into four separate fuels: a solid fuel, an emulsified solid in the liquid solvent phase by blending the solid, the solvent and a surfactant, an aqueous phase, and the recovered liquid solvent phase. Petroleum is the preferred solvent and the separation may be any conventional means. The mixture preferably consists of 1 part by weight animal waste, about 1.5 parts by weight diesel and between about 0.11 to about 1.86 parts by weight a water/alcohol solution. The water/alcohol solution is between about 5% to about 85% alcohol before heating. Additionally, an alkali base may be added to increase waste solubility.
