Chapter 22: Problem 23

Explain what is meant by coal gasification.

Short Answer

Expert verified
Coal gasification is the process of converting solid coal into a gaseous state, primarily including components such as carbon monoxide, hydrogen, carbon dioxide, and methane, by reacting it at high temperatures and pressures with oxygen and steam. The gas produced, syngas, is often used for electricity generation and in other chemical processes.

Step by step solution

01

Definition of Coal Gasification

Coal gasification is a thermo-chemical process in which coal is transformed into a gas. It is essentially the conversion of solid coal into a gaseous form.
02

Process Explanation

This process involves reacting the material (coal) at high pressures and temperatures with a controlled amount of oxygen and steam. The primary constituents of the resulting gas are carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), and methane (CH4).
03

Purpose and usage of resultant gas

This resulting gas, known as syngas, can be further used to generate electricity or can be used in other chemical processes to produce products such as fertilizers, fuels, and other chemicals.
