Abstract

A method of operating a cyclic synthesis gas-ore reduction process comprising supplying a carbonaceous material and preheated oxygen to a synthesis gas reactor to produce a hot synthesis gas, partially cooling said hot synthesis gas by directly passing the same through a regenerator and thereby storing the sensible heat of the hot synthesis gas in said generator. Further cooling said synthesis gas by reheating liquid for a vapor generator, and then reheating said further cooled synthesis gas and supplying it to an ore reduction reactor and generating a reduced product and an off gas. Directing the generated off gas to the synthesis gas reactor via said regenerator to heat the off gas to around 100.degree. C. by transferring said stored heat.
