Sulphuric acid is made by the oxidation of sulphur or pyrites into sulphur dioxide (S to SO 2).The sulphur dioxide is changed to sulphur trioxide by means of a catalyst.Then the sulphur trioxide reacts with water to form sulphuric acid (HOH + SO 3 →H 2 SO 4).There are two common methods of making this acid: the Contact process and the .
The Clean Air Act, especially after amendments passed in 1990, drove a shift toward low-sulfur coal as one of the main methods of reducing sulfur dioxide emissions from coal plants.Since the predominantly subbituminous coal west of the Mississippi emits much less sulfur per unit of energy, this trend favored western surface mines as a dominant .
