Abstract

An endothermic chemical system composed of pulverized iron-based oxide and carbon powder has been investigated by using the temperature swing method (TSM) at 700 to 800 °C. Ferrite of Mn and Zn, and magnetite were studied. The last material showed the most promising result. In the TSM, magnetite as the working material was reduced to wustite and carbon was concurrently oxidized to CO in a flow of N2 gas at 800 °C (the activation step of the metal oxide). In the reverse process, in a flow of CO2, the wustite was oxidized to magnetite and injected CO2 was reduced to CO at 700 °C (the reduction step of CO2 to CO). Following the reduction step, the chemical composition of the magnetite phase was restored to that existing prior to the activation step. The total amount of oxygen donated to carbon during the activation step was the same as that taken from the magnetite during the reduction step. In this system, the following net reaction can be realized at temperatures of 700 to 800 °C: C + CO2 → 2CO. The process will therefore serve for the utilization of coal and other carbonaceous compounds in much lower temperatures than are employed in the traditional water gas and producer gas reactions.
