Explanation of Solution

Pyrolysis is the process in which combustion takes place in the absence of oxygen. It is the thermal method of decomposition at high temperature in a nonreactive environment. This method is mainly used for decomposition of organic waste. Generally, the organic substance is volatile in nature so, during pyrolysis, they leave the solid material and gets evaporated at an elevated temperature which is enriching in carbon and charcoal.

Gasification is the process in which the organic matter is decomposed in the presence of oxygen at elevated temperature. In this process, organic matter is disintegrated into hydrogen, carbon monoxide, and carbon dioxide. The product of this process is used as a renewable source of energy.

A steel, possessing an eutectoid composition, undergoes a gradual cooling process from 800°C to 600°C. Outline the transformation, equilibrium microstructure, and provide approximate component proportions. Describe the resultant non-equilibrium microstructure in two scenarios: a) the steel is rapidly cooled from 800°C to 600°C within 1 s, and then held at such temperature; b) the steel is rapidly cooled from 800°C to 600°C within 1 s, maintained at this temperature for 5 s, and subsequently quenched to room temperature. Use the provided diagrams. Temperature (°C) 1600 1538°C 1493°C 1400 L 1394°C Y+L 1200- 1147°C 2.14 Y.
