Sulfur dioxide, optimization oxidation

Mass spectral analysis of the samples at several different temperatures show the exit gas stream to contain in addition to oxygen carbon dioxide, carbon monoxide, sulfur dioxide, and some carbonyl sulfide. The primary sulfur containing gas in the stream is sulfur dioxide ( 1%) however, a small amount of carbonyl sulfide ("0.1%) appears to be present. For any quantitative work it will be necessary to monitor the carbonyl sulfide or to optimize reaction conditions and/or add a secondary oxidation stage to decrease its concentration to a negligible level. It should be noted that mass spectral analysis of the exit gas during the sulfur dioxide peaks gave no evidence for the presence of gaseous hydrocarbons or sulfur trioxide. 

Leitenberger s work (1939) is concerned with the oxidation of sulfur dioxide in adiabatic beds and tubular reactors. Using the Boresskow-Slinko kinetic equation he calculated the optimal tem-6... 

Lee and Arts (1963) solved the problem of the optimal design of a multibed adiabatic converter using dynamic programming. Specifically, they selected the case of sulfur dioxide oxidation. 

Chartrand and Crowe (1969) used the following experimental data on the catalytic oxidation of sulfur dioxide in an existing four-bed converter of the Canadian Industries Ltd. to optimize the operation. 

One step in the manufacture of sulfuric acid is the oxidation of sulfur dioxide to sulfur trioxide. Consider performing this oxidation at a pressure of 1 bar with an excess of 100 mole % oxygen, using air as the oxygen source. For the optimal yield of SO3, it is desirable to maintain the reactor at a constant temperature of 700°C. You may assume Ah is independent of temperature.
