Jan 30, 2023 · The Contact Process is used in the manufacture of sulfuric acid. This Modules explain the reasons for the conditions used in the process by considering the effect of proportions, temperature, pressure and catalyst on the composition of the equilibrium mixture, the rate of the reaction and the economics of the process.
Revision notes on The Contact Process for the CIE IGCSE Chemistry syllabus, written by the Chemistry experts at Save My Exams.
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5 ) is now preferred.
The contact process is a present method of producing concentrated sulphuric acid which is required for industrial use. The catalyst used during the process is vanadium oxide. The contact process is divided into three stages: 1 Stage: Sulphur dioxide preparation and purification.
A brief summary of the Contact Process. The Contact Process: makes sulphur dioxide; converts the sulphur dioxide into sulphur trioxide (the reversible reaction at the heart of the process); converts the sulphur trioxide into concentrated sulphuric acid. Making the sulphur dioxide. This can either be made by burning sulphur in an excess of air:
Contact process, modern industrial method of producing sulfuric acid; it has largely replaced the chamber, or lead-chamber, process. Sulfur dioxide and oxygen, passed over a hot catalyst, unite to form sulfur dioxide, which in turn combines with water to make sulfuric acid.
The contact process, for making sulfuric acid, is a process which involves a. reversible reaction. . The raw materials needed to make sulfuric acid are: sulfur. air. water. Stage one – making...
