Abstract: Disclosed is a process for purifying tail gases from an ore-smelting electrical furnace by catalytic oxidization, which comprises: impregnating a catalyst carrier in an impregnating solution, then aging, calcinating, and finally drying, so as to prepare a catalyst of high efficiency; then washing the tail gases from an ore-smelting electrical furnace with an aqueous alkali-containing solution, pre-heating the alkali-washed tail gas; and adjusting the oxygen volume content in the tail gases, charging the tail gases at a certain speed, purifying the gases by a catalytic oxidization fixed bed containing the catalyst of high efficiency, cooling the purified gas, so as to obtain the feed gases for C1 chemistry.
