Synthesis and characterization of NH4-P, a new Zeolite for post-Catalyzing the Claus Process Mahboobeh dashti Ardakan

It is well known that hydrogen sulfide is deleterious to the general environment and is harmful to the health of workers in various industrial plants and areas. It has been an accepted fact that this material must be removed from process effluent streams before these streams are allowed to pass into the atmosphere. the well -known process for this clean up is the CLAUS process, which consists of burning a part of hydrogen sulfide to produce sulfur dioxide and promotes oxidation of the hydrogen sulfide by the sulfur dioxide to yield elemental sulfur and water.2H2S+SO2=2SO2+2H2O,2H2S+SO2=3S+2H2O yield 2/3 . a claus reactor in good operating condition will convert up to about 97 percent of the hydrogen sulfide and sulfurous oxides to elemental sulfur and water. generally the degree of conversion which can be expected from a claus reactor is in the range of about 80 percent to about 95 percent. such a significant removal of hydrogen sulfide from the atmosphere has up to this time been quite sufficient.
