Technical data

Sulphur trioxide - the sulphuric acid contact process

Article no: P3110400

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

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