  abstract: The adsorptive characteristics of ammonia and the capacity of
  abstract: ammonium carbonate salts on various sorbents were
  abstract: investigated. Selexsorb CDX was found to be the most
  abstract: effective sorbent for ammonia and ammonium carbonate salts.
  abstract: The adsorption of pure S02 and C02 as well as S02 in
  abstract: simulated flue gas on the Selexsorb CDX also has been
  abstract: assessed. The Selexsorb CDX displays an excellent adsorption
  abstract: capacity not only for ammonia but also for S02- The study
  abstract: of S02 removal by Selexsorb CDX impregnated with ammonia or
  abstract: ammonium carbonate salts has been performed experimentally in
  abstract: a packed column under two ammonia concentrations and various
  abstract: temperatures. The S02 removal was favored at low
  abstract: temperatures for all reaction systems. The Selexsorb CDX
  abstract: impregnated with ammonia solution (47.34%) was found to be
  abstract: the most promising sorbent in the removal of S02 at 298 K in
  abstract: this study. The S02 removal capacity is 156mg/g and the
  abstract: corresponding ammonium sulfate yield is 320mg/g with the S02
  abstract: removal efficiency 90%. The extracted products solution and
  abstract: its respective crystalline solid were analyzed and determined
  abstract: by wet chemistry, pH measurement, XPS and FTIR. The main
  abstract: reaction product for NH3(,,,) + C02 was ammonium
  abstract: bicarbonate. Our XPS surface analysis indicated that
  abstract: ammonium sulfate was the main product before extraction
  abstract: operation for S02+NH3(47.34%)+CO2 and S02+NH3(47.34%)
  abstract: systems. The product was easily oxidized to form ammonium
  abstract: sulfate. This was further confirmed by the FTIR analysis for
  abstract: the respectively extracted solid products. The regeneration
  abstract: experiment of the spent Selexsorb CDX was also conducted.
  abstract: The experimental results demonstrated that the sorbent is
  abstract: easy to be regenerated under nitrogen flushing at 433K
  abstract: following the product extraction operation. The study
  abstract: results have shown the potential for removing S02 from flue
  abstract: gas via the Selexsorb CDX soaked with high concentration
  abstract: ammonia solution or its carbonate salts to produce ammonium
  abstract: sulfate. Comparing the whole operation and process to the
  abstract: traditional FGD process, this new procedure for sulfur
  abstract: dioxide removal may be very promising for industrial
  abstract: application.
