Latest Patents

Tamaki's latest patents include a heavy oil emulsion fuel composition and a process for producing an oil-in-water type heavy oil emulsion fuel. The first patent describes a heavy oil emulsion fuel composition that contains heavy oils, such as bitumen and asphalt. This composition serves as a substitute fuel for heavy fuel oils and boasts enhanced combustion efficiency, which helps reduce soot, dust, and nitrogen oxides after combustion. The formulation includes 40 to 85% by weight of heavy oil, 10 to 40% by weight of water, 0.1 to 5% by weight of a surfactant, and at least 0.1% by weight of specific water-soluble compounds or monohydric alcohols.

The second patent details an oil-in-water type heavy oil emulsion fuel characterized by a specific and broad particle size distribution. This emulsion has a viscosity close to that of water, allowing for sufficient atomization at temperatures ranging from room temperature to 90°C. It exhibits excellent handleability and fluidity, even with a high concentration of heavy oil, and maintains stability without precipitation or increased viscosity over time. This innovation allows for the use of the emulsion as a substitute fuel for heavy fuel oil without requiring modifications to existing boilers.
