The process of rapidly heating coal in the absence of air is known as a destructive distillation of coal. When coal is burned in the presence of air, it burns primarily to create carbon ...
WhatsApp: +86 18203695377Coking. Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, which makes it burn faster (as ...
WhatsApp: +86 18203695377Coke, coal gas, gas carbon, coal tar, ammonia liquor, and cola oil are the examples of the substance that are obtained by the destructive distillation of coal. Hence, the solid fuel formed by heating coal in the absence of air is "Coke" and the correct answer is option B. Note:

WhatsApp: +86 18203695377Destructive distillation of coal involves heating coal to high temperatures (about (1000,^circ {rm{C}})) in the absence of air. The process causes its decomposition into different products solid and gaseous. Some of the gases condense while some dissolve in water. Some of the products obtained in the process are coke, coal, coal tar, and ...
WhatsApp: +86 18203695377Correct option is B) A solid fuel formed by heating coal in the absence of air is coke. Coke is black colored, tough porous substance. It is pure carbon. It has applications in steel manufacture and in the metallurgy.
WhatsApp: +86 18203695377The correct option is C destructive distillation of coal. When the coal is heated in the absence of air, it does not burn but produces many products. This process of heating coal in the absence of air is called destructive distillation of coal. The main products are coke, coal tar and coal gas. Suggest Corrections.
