Manufacture of Sulphuric Acid 1. Sulphuric acid can be prepared by using the contact process using vanadium(V) oxide as a catalyst. 2. There are three main stages in the manufacture of sulphuric acid namely . ( a ) Combustion of sulphur ( b ) Conversation of sulphur dioxide to sulphur trioxide ( c ) Formation of sulphuric acid 3. The process at each stage manufacture of sulphuric acid Stage 1: Combustion of sulphur • sulphur is burnt in the air to produce sulpur dioxide •sulphur dioxide must be purified to remove foreign compounds which may poison the catalyst S(l)+O2(g)----->SO2(g) Stage 2: Conversation of sulphur dioxide to sulphur trioxide • the sulphur dioxide produced together with air are passed over vanadium oxide(V2O5) catalyst at a temperature of 450--500°C to produce sulphur trioxide •SO2(g)+O2(g)----->2SO3(g) Stage 3: Formation of sulphuric acid • sulphur trioxide i...
