Question

Which of the following is present at the time of cracking of hydrocarbons?

• A. Copper
• B. Zeolite
• C. Nickel
• D. Molybdenum

Answer 1

The correct option is B Zeolite

A Catalyst is a substance which accelerates the rate of a chemical reaction without undergoing any change in its chemical composition or mass during the reaction. A catalyst accelerates the rate of a reaction by lowering the activation energy.

Hydrocarbon cracking is the process whereby large and heavy hydrocarbon molecules (long-chain hydrocarbons) are broken down up into simpler and smaller bits as light hydrocarbons (short-chain hydrocarbons) by breaking carbon-carbon bonds in cracking stock.
In new designs, very active zeolite-based catalyst are used. These catalysts characterize a short-contact time to cracking stock.

Hence, the correct option is $\text{B}$
