The invention discloses an adsorption method for removing acid gas pollutants from a liquid or a gas. The method comprises providing an activated alumina adsorbent, the adsorbent is selected from one or more alkali metal compounds, one or more alkaline earth metal compounds. Or a group of compounds impregnated with a mixture of these compounds; contacting the liquid or gas containing the acid gas pollutant with the activated alumina adsorbent to sufficiently adsorb the acid gas pollutant in the liquid or gas to reduce the liquid or Contaminant content of gases. The alumina sorbent is formed from coalesced, calcined alumina powder and has a mercury pore volume of at least 0.10 cc / g with a porosity greater than 500 Angstroms. |
