What are the products of destructive distillation of coal?

Explanation

Destructive distillation is a chemical process in which decomposition is achieved by heating to a high temperature; the term generally applies to the processing of organic material in the absence of air or in the presence of limited amounts of oxygen. The process breaks up large molecules. 'Coke, coal gas, gaseous carbon, coal tar, ammonia liquor ,and coal oil' are examples of commercial products historically produced by the destructive distillation of coal.
