Removal of CO2 from the reducing gas (mainly H2 and CO) fed to a direct reduced iron (DRI) process, such as the COREX SYMBOL 210 \f "Symbol" process, can be accomplished by adsorptive separation, e.g. a GEMINI-4 or GEMINI-5 process. The process described herein is a four bed system with six process steps. A schematic of the suggested cycle and process is given in Figures 1 and 2. A brief description of the six process steps is given below.
