coal tar distillation process. 12.2 coke production. sulfide ammonia and nitrogen. liquid products include water tar and crude light oil. the coking process produces approximately 338 000 l of coke oven gas (cog) per megagram of coal charged (10 800 standard cubic feet of cog per ton).
coal tar is the destructive distillation of bituminous coal. coal tar is distilled into many fractions to yield a number of useful organic products like benzene, toluene, xylene, naphthalene, anthracene, etc.

the penetration bitumen grades range from 15 to 450 for road bitumen. but the most commonly used range is 25 to 200. this is acquired by controlling the test carried out i.e. the distillation process. the partial control of fluxing the residual bitumen with the oils can help in bringing the required hardness.
