We tested the use of Ba<SUB>2</SUB>TiO<SUB>4</SUB> to remove CO<SUB>2</SUB> from steam reforming gas of CH<SUB>4</SUB> and thereby increase the concentration of H<SUB>2</SUB> in the gas. The results of passing reforming gas through a reactor filled with a CO<SUB>2</SUB> absorbent based on Li<SUB>4</SUB>SiO<SUB>4</SUB> ceramics at 600 to 700°C demonstrated that the concentrations of CO<SUB>2</SUB> and CO were reduced, while the H<SUB>2</SUB> concentration was increased to about 95%, by the progression of the water shift reaction. At a temperature of 650°C or less, or a space velocity of 250 h<SUP>–1</SUP> or less, the use of a shift reactor might not be necessary after the reforming because the CO concentration was less than 2000 ppm.
