  • Publication number: 20170066650
    Abstract: Processes and units are provided, which carry out cyclic steps of zinc oxidation and reduction of zinc oxide to combine an exothermic heat delivering step with an endothermic syngas production step, respectively. Both steps use zinc as the pivotal element that enables the process to be carried out cyclically. Heat is delivered from the exothermic step to the endothermic syngas via heat storage elements of various types which are arranged according to the reaction's conditions and characteristic temperatures. Thus, energy efficient syngas production methods and units are provided.

  • Publication number: 20040237499
    Abstract: The present invention suggests a safe process and system for generating energy, which may be used for transportation applications such as car propulsion. More particularly, the process of the invention is for producing mechanical work from heat generated by at least one exothermic chemical reaction. In each step of the process, at least part of the heat is generated by a process comprising introducing into a reaction chamber a metal from a metal reservoir and an oxidizer from an oxidizer reservoir. The metal and the oxidizer used in this process are of kinds that react exothermally with each other, and the oxidizer is oxygen of ambient air or is of a condensed phase origin.
