Catalyst used in isomerisation process is __________________ ?
Correct answer: D. AlCl3
- A. H2SO4
- B. H3PO4
- C. HF
- D. AlCl3
Explanation
Aluminium chloride, usually with hydrogen chloride, is the classical catalyst system for hydrocarbon isomerisation. Sulphuric acid, phosphoric acid and hydrofluoric acid are more characteristically used in other acid-catalysed refinery processes.
