Principle

The contact process is currently used in the chemical industry to produce sulphuric acid in the high concentrations needed for industrial processes. In this model experiment, platinum-palladium-aluminium-oxide beads are employed as a catalyst for the reaction.

Benefits

  • Stable and safe setup due to solid stand material
  • Secure connection of the items by GL screw joint system

Tasks

  1. Oxidise sulphur dioxide to sulphur trioxide.
  2. Use the sulphur trioxide to produce sulphuric acid.
