Several samples of lithium zirconium silicate prepared by solid-solid fusion method were calcined in air or nitrogen atmosphere at 900°C for 3h. The lithium zirconium silicate samples were characterized by acidity/alkalinity, surface area, XRD pattern, SEM images, and CO2 sorption. The alkalinity and surface area of the samples of lithium zirconium silicate were found to be in the range of 15.1 to 20.0mmolg−1 and 0.05 to 2.13m2g−1, respectively. The temperature profile of CO2 sorption by samples of lithium zirconium silicate was given for the range 100 to 700°C. The CO2 sorption was found to be in the range of 12.81 to 18.04wt.% at 550°C for samples of lithium zirconium silicate with different Li/Zr/Si mole ratios from 1 to 6. The crystalline phases in the samples of the lithium zirconium silicate, Li6Si2O7, ZrSiO4, Li2SiO3, Li2ZrO3, Li4ZrO4, and Li4SiO4 could contribute to CO2 capture. The conversion of CO2 by methane to syn-gas over the lithium silicate samples and PdO (5wt.%)/Al2O3 at 500°C with the gas hourly space velocities 6,000, 12,000, and 36,000mLh−1g−1 of methane and 6,000mLh−1g−1 of CO2 was explored. However, the higher conversion of CO2 to syn-gas was observed at the low gas hourly space velocity of 6,000mLh−1g−1 of methane.
