Abstract:
     The invented desulfurizer is characterized in that its composition contains (by wt.): alkaline compound of Na 1-20%, mass-transfer accelerator 0.01-1.0%, and the rest is desulfurizing carbon; wherein the alkaline compound of Na is one of NaOH, NaHCO3, Na2CO3, sodium oxalate; mass-transfer accelerator is oxygen-contained organic alcohol, acid and sodium salt of organic acid. The present invention can use existent dry method desulfurizing equipment and technology, high in sulfur capacity, so that it can reduce desulfurization treatment cost greatly.
