Chapter 22.5, Problem 37LC

Interpretation Introduction

Interpretation- Importance of cracking step in the petroleum refining process.

Concept Introduction- Petroleum is a mixture of many hydrocarbons with $1$ carbon to $40$

carbon atoms. This crude oil is not very useful until it is refined, and its component is separated. The refining process is very complex but the following are the basic steps:

1. Distillation
2. Cracking
3. Reforming

Answer to Problem 37LC

Cracking breaks down hydrocarbon into smaller and more useful molecules like gasoline and kerosene.

Explanation of Solution

Cracking is a process in which hydrocarbons are broken down into smaller and more useful components. The molecules are cracked with the help of a catalyst and heat. It produces more useful components like gasoline and kerosene. It also produces low molecular mass molecules which can be used in paints and plastics.
