1.Desulfurizer
generally refers to removing fuel, materials or other materials of free sulfur or sulfur compound agent; In the
pollution control and processing refers to can remove sulfur in gas oxide (including SO2 and SO3) used by
the agent. All kinds of alkaline compound can be as desulfurization agent.
Removal of so2 in flue gas desulfurization agent, the most is cheap lime, limestone and calcareous agent by alkaline solution. The flue gas desulfurization agent can absorb most of so2 fixed in the fuel in the slag. Chemical plant,
refinery and often use soda ash alkaline aluminium sulphate and solution as desulfurizer treatment including so2 tail
gas, and desorption recycling.
2.Ferric Oxide Desulfurizer
Ferric oxide desulfurization agent is a kind of solid desulfurizing agent, its principle is the waste gas containing
sulfur compound adsorption to the desulfurizer in holes, and purge gas. When the desulfurizer after reach saturation, i.e., it no longer has the desulfurization ability is, we need to carry on the regeneration, such as by steam for
stripping regeneration. However, ferric oxide desulfurizer in use for a long time, the activity will continue to drop in, as the holes by some impurity content have congestion, then desulfurizer loses it live. Waste desulfurization agent
can be recycled with one of the active ingredient.
this product can be used for natural gas, coke oven gas, water gas, oil field gas, methane, H2, CO2, chemical
synthesis gas (such as methanol, acetic acid, DMF, ammonia, polypropylene) gas removal from the sulfide.

usage in food grade CO2 ,Methanol feed gas ,and so on .
Desulfurizer and rebirth principle :
Fe2O3 . XH2O+3H2S==Fe2S3.XH2O+3H2O(desulfurizer formula)
Fe2O3 . XH2O+CS2==Fe2S3.XH2O+3H2O(desulfurizer formula)
Fe2O3 . XH2O+3/2O2==Fe2O3.XH2O+3S (rebirth formula )
H2S with activated iron chloride of desulfurizer effect become sulfide ,when the raw material including O2 ,
desulfurizer with O2 reaction creat simple substance deposit in desulfurizer micropore , the desulfurizer can
rebirth , can reach desulfurizer effect .
