Six　natural　mineral　sorbents　and　a　series　of　self-made　sorbents　were　used　to　remove　alkali-metal　vapor　from　high-temperature　coal　gas.　Results　indicate　that　the　self-made　sorbent　GM6　is　the　best　sorbent　with　the　highest　sodium　compound　content,　under　the　conditions　of　1173　K,　a　gas　velocity　of　16　L/min,　a　reaction　time　of　3　h,　and　a　NaCl　concentration　of　0.13　mg/L.　It　is　shown　that　the　sodium　compound　content　is　dependent　on　the　chemical　constituents　and　the　microporous　structure　of　sorbent,　based　on　the　surface　area　data.　Results　of　X-ray　diffraction　(XRD)　analysis　and　the　kinetics　indicate　that　the　adsorption　process　of　GM6　is　physical　adsorption　in　an　N-2　atmosphere　and　it　is　controlled　by　the　diffusion　of　a　sodium　resultant　layer.　The　adsorption　process　in　a　N-2/H2O(2%)　atmosphere　is　mainly　a　chemical　adsorption　that　is　controlled　by　both　the　chemical　control　and　the　product-layer　diffusion　control.
