Abstract

H2S, pure or in gaseous mixts. is forced through a refractory furnace contg. either a solid made porous by virtue of small channels 10-40 mm dia. or a molten metal (Sn, Cu, Fe, Mn, Ni or their alloys) maintained at least at 1200 degrees C, pref. 1300-1400 degrees C. After the gases have passed through the solid or molten metal (in about 1 sec.) the emergent gases are immediately quenched to 140 degrees C by a counter-current spray of water or liq. S which is then recycled. The furnace may be heated by induction or dielectric heating. The porous solid can be made from Cr, Ti, Mo, V or graphite. Rapid quenching of the decomposed H2 and S prevents the reverse reaction producing H2S. The furnace is resistant to corrosion.
