Most sulfuric acid is produced by the modern contact process. First, elemental sulfur or sulfide ores are heated with oxygen to produce sulfur dioxide (SO2). About 60 percent of the sulfur dioxide produced throughout the world comes from burning sulfur, and approximately 40 percent is derived from roasting sulfide minerals. (Roasting is the process by which ores are oxidized by heating in air.) Sulfur dioxide is then oxidized to sulfur trioxide, SO3. This oxidation reaction is exothermic (i.e., releases energy in the form of heat) and reversible. Accordingly, a vanadium oxide catalyst is used on an inert support to increase the rate of the oxidation without decreasing the yield. Under optimum conditions, the feed gas consists of equimolar quantities of oxygen and sulfur dioxide (i.e., a 5:1 ratio of air to sulfur dioxide) that passes through a four-stage catalytic converter operating at various temperatures. After the gas mixture has passed over three of the catalyst beds and approximately 93 percent conversion to sulfur trioxide has occurred, it is cooled and absorbed into sulfuric acid in ceramic-packed towers. A final conversion of greater than 99 percent is achieved after passage through the final reaction bed. All three reactions used to produce sulfuric acid, as shown below, are exothermic. Efficient utilization of this energy to generate electricity, for example, is a key component in maintaining the inexpensive price of this heavily used acid.
