Common industrial chemical reactions

Question 1

What are the conditions required for catalytic cracking?

Answer 1

Catalytic cracking takes place high temperatures of around 450°C, low pressures and the presence of zeolite catalyst.

Question 2

What are the conditions required for reforming?

Answer 2

Reforming takes place under high temperature of around 500°C, where gaseous reactants are passed over platinum catalyst suspended on a bed of aluminium oxide.

Question 3

What conditions are required for isomerisation?

Answer 3

Isomerisation takes place under high pressures of around 20 atm (2,000 KPa) and temperature of 250°C in the presence of platinum catalyst on a zeolite base.

Question 4

What conditions are required for polymerisation?

Answer 4

Temperatures of around 60°C and Ziegler-Natta catalysts such as TiCl₃.

Question 5

What conditions are required for the hydration of ethene?

Answer 5

• Phosphoric acid catalyst.
• 300°C temperature.
• 80 atm (8,000 KPa) pressure.
