| titleOfInvention | A kind of modification type porous calcium carbonate adsorbent and its preparation method and application |
| abstract | The invention discloses a kind of modification type porous calcium carbonate adsorbents for belonging to purifying coal-fired flue gas technical field and its preparation method and application.The modification type porous calcium carbonate adsorbent, using bromide as dressing agent, dipping modification is carried out to porous calcium carbonate using the porous calcium carbonate that SDS is template preparation as matrix, and grinding after drying is made, in the deep purifying that can be applied to coal-fired flue-gas.The adsorbent has larger specific surface area, can adsorb majority of gas and particulate matter, especially sour gas such as SO simultaneously 2 、SO 3 , condensable particulate matter and Hg 0 .Calcium carbonate after adsorption saturation can return to limestone slurry liquid preparing system, be used as new desulfurization absorbent, and adsorbed product SO 3 2‑ 、SO 4 2‑ , condensable particulate matter then become calcium sulfite or calcium sulfate and enter slurries, finally enter gypsum, not will produce secondary pollution, prepare low raw-material cost, it is simple for process, easily realize industrialization. |
