Latest Patents

One of Takashima's latest patents is a method of and apparatus for power generation. This invention involves the thermal decomposition of a reactant, XY, which occurs on a negative catalytic electrode to produce products X and Y. The product Y acts as a cellular reaction material, separating into ions, Y.sup.+, and electrons, e.sup.-, on the negative catalytic electrode. The ions Y.sup.+ traverse through a solid electrolyte, while the electrons e.sup.- flow through an external resistor. The product X, generated on the negative catalytic electrode, is then circulated to the positive catalytic electrode, effectively reproducing the reactant XY. This innovative approach allows for the efficient conversion of heat energy into electric energy, surpassing conventional methods. In one embodiment, the reactant XY is 2-propanol, with the resulting products being acetone and hydrogen.

Another significant patent by Takashima is a catalytic reaction method. This apparatus includes a catalytic reaction vessel containing a catalyst for an exothermic reaction. The vessel features first and second catalyst regions, each containing a catalyst with differing catalytic performances. Multiple raw materials are introduced into the vessel and passed through these regions to react and generate heat. This heat is then transferred to a heat medium located outside the vessel, allowing for controlled temperature distribution within the catalytic reaction vessel. The variation in catalytic performance is achieved by adjusting the concentration of the catalyst or utilizing different catalyst species.
