Title: Process for oxidation of so2 to so3
IPC: C01B17/765
Filed: 1968-11-25
Abstract: SO 2 is converted to SO 3 by catalytic stages, in which part of the gases which are to be reacted are carried, after preliminary heating to at least starting temperature, to a preliminary catalyst arranged in front of the main catalyst at a rate of flow of from 0À2-6 m./sec. based on empty space such that temperatures of 600 C. are not exceeded in the preliminary catalyst, the gases leaving the preliminary catalyst are cooled with a further part of SO 2 containing gases such that the temperature of the gas mixture does not lie below the starting temperature of the main catalyst, and the SO 2 contained in the gas mixture is substantially converted to S0 3 in the main catalyst. About 30-90% of the theoretically possible extent of conversion of SO 2 may be achieved in the preliminary catalyst. Starting temperatures for the preliminary catalyst are from 420-450 C. when a V 2 0 5 catalyst is used. Inlet temperatures to the preliminary catalyst may exceed this by 10-30 C and to the main catalyst by up to about 20 C , a preliminary conversion of about 10-30% by volume thus being achieved. SO 2 sources include roasting of pyrites, zinc blendes and other sulphides, decomposition of sulphates or combustion of sulphur. If sulphur combustion gases are used these may be mixed with cold SO 2 containing gases from decomposition or roasting, after the preliminary catalyst. Starting gases normally contain 8-12À5% SO 2 , but should not exceed 8% at the entry to the main catalyst.
