Question
Destructive distillation of bones produces _______ along with bone oil and organic compounds.
- Soft coke
- Coal
- Bone coal
- Bone black
Hint:
Bone char is a black, porous, granular substance produced by heating bones at high temperature and low oxygen concentration, and destructive distillation is basically the process of breaking down organic raw materials.
The correct answer is: Bone black
The correct option is d)Bone black.
- Animal charcoal is made from bones, horns, blood, etc. Bone black or bone char is obtained by destructive distillation of bones in iron retorts, the distillate forming bone oil or dippel's oil.
- The bones of these animals are heated to temperatures of about 700°C in a sealed container by a process called destructive distillation, and the oxygen concentration is kept very low as this can affect the adsorption quality of the product.
- The organic matter contained in the bones is dispersed by heat, and the organic matter that is not expelled is recovered as the final product, activated carbon.

Read the following paragraph carefully.
X is prepared when the wood is heated in a limited air supply. This X is used to increase the absorption capacity of gases by heating them at a very high temperature. The substance obtained by this process is called Y. When this X reacts with the oxide of the metal, it gives the mixture of Z and W. This mixture is also called producer gas.
Identify the compounds X, Y, and Z in the above paragraph.
