existing in the pet coke, pet coke can be sorted as low sulfur pet coke (less than 3%) and high sulfur pet coke (more than 3%) [1]. Low sulfur pet coke which is known as carbon grade pet coke, can be used to produce graphite electrode or carbon products, and also used in the steel and aluminum industry. High sulfur pet coke cannot be used as ...

By. admin. India annually consumes around 27 MT of pet coke. It is nothing but a dark solid carbon material left out by petroleum refineries that emit 11 per cent more greenhouse gases than coal. In August 2018, the Supreme Court put restrictions on free import of pet coke. The authors look at the options for the cement industry.

Pet coke, also known as petroleum coke, refers to a solid carbon byproduct produced in the oil refining process. It consists of elemental forms of sulfur, metals, and nonvolatile inorganic compounds. Pet coke is highly stable and nonreactive under ambient conditions, has high calorific power and low ash content, and does not dissolve in water.
