Abstract: A process is disclosed for treating microporous coating layers deposited by anodic oxidation or plasmachemical anodic oxidation on objects made of aluminium, magnesium, titanium or their alloys. The process is useful to permanently seal the microporous coating layer and thus to protect the base material against corrosion and wear. For that purpose, silicic acid in the form of a silicic acid lyosol is deposited into the pores or capillaries of the microporous coating layer. In the silicic acid lyosol, the colloidally distributed SiO2 particles have at least one dimension smaller than the diameter of the pores or capillaries. The sol thus deposited into the pores is then coagulated or made to react with the coating layer.

The hydrogen sulfide contaminated gas along with a gas containing free oxygen is passed through a series of hydrogen sulfide oxidation zones containing an oxidation catalyst, such as one or more oxides or salts of Ni, Co, Fe, Cu, Ag, Mn, Mo, Cr, W and V, deposited on a support, such as bauxite, activated alumina, titania and activated carbon. The initial and intermediate catalyst beds are operated adiabatically by injecting a substoichiometric amount of oxygen into the gas to be treated with respect to the amount of hydrogen sulfide present in the gas so that the temperature does not exceed 150 DEG  C. The final catalyst bed is operated under conditions such that a superstoichiometric amount of oxygen is injected into the gas with respect to the hydrogen sulfide and cooling is provided so that the temperature does not exceed 150 DEG  C. The invention is able to maintain an optimum selectivity toward sulfur during the catalytic oxidation of the hydrogen sulfide by controlling the temperature.
