Who makes needle coke in India?

Needle Coke | Products | Mitsubishi Chemical Corporation.

Who makes needle coke?

The world’s largest manufacturer of needle coke is Conoco Phillips (Phillips 66). There are only 2 companies in the world which derive needle coke from coal tar pitch. Both the companies are Japan based. As of 2021, the global EAF based steel production is expected to witness high growth rate.

Where does needle coke come from?

Needle coke is produced exclusively from either fluid catalytic cracking (FCC) decant oil or coal tar pitch. Honeycomb coke is an intermediate coke, with ellipsoidal pores that are uniformly distributed.

What is needle coke?

Needle coke is a specialty grade of pet coke valued for its crystalline structure that makes it a good material for making electrodes. Needle coke is typically produced from a dedicated coker that uses low-sulfur FCC slurry as feedstock.

How is petroleum needle coke made?

Petroleum needle coke is produced at oil refineries by converting decant or slurry oil, along with high-quality vacuum residue, both by-products of the refining process.

What is a graphite electrode?

Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath. They are typically made using premium petroleum needle coke, coal tar pitch, and some additives (Fruehan, 1998).

How is needle coke used in lithium ion battery?

Abstract. Needle coke, the remaining material after refining petroleum, is used as an anode of a lithium-ion secondary battery. Sulfur is separated from the needle coke to below 0.1wt. \% using the molten caustic leaching (MCL) method developed at the Korea Institute of Energy Research.

Is coke obtained from coal?

Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.

Is pet coke banned in India?

The Supreme Court has banned the use of petroleum coke or petcoke — solid-carbon, coal-like material which results from oil refining — and furnace oil in the National Capital Region (NCR) and suggested that similar steps be taken in other States.

What is graphite coke?

Synthetic graphite is a manufactured product made by high-temperature treatment of amorphous carbon materials. In the United States, the primary feedstock used for making synthetic graphite is calcined petroleum coke and coal tar pitch, both of which are composed of highly graphitizable forms of carbon.

What is graphite petroleum coke?

Petroleum coke (petcoke) is the gray-to-black solid carbonaceous residue left by the destructive distillation of petroleum residua. Carbon has two natural crystalline allotropic forms: graphite and diamond. Graphite is a highly refractory material with a high melting point.

Can you make graphite from coke?

Graphite is produced naturally, but it is usually commercially produced by treating petroleum coke. Coke is a byproduct of the destructive distillation of coal. While it is possible to convert carbon into graphite, this process requires industrial equipment not available to the average individual.

Can graphite electrode India turn the tide?

Back in India a humble manufacturer of Graphite Electrode was trying to turn the tide. HEG India was already burdened with losses and significant debt as of FY 2017. Very few people saw the stock as a worthwhile investment opportunity until the Chinese sneezed.

How much does a graphite electrode cost?

Based on data from the past two quarters, HEG has been selling its graphite electrodes at an average price of about $15,000 per tonne. Its also running at peak capacity, meaning they can’t grow by selling more (Huge expansion sprees are also out of the question because it’s hard to source needle coke, the raw material used to produce GE).

Did Chinese policy push India’s graphite electrodes to the stars?

When the rush for Graphite electrode (GE) began last year, the entire investor community started focusing on the Indian twins- Graphite India Limited and HEG India, two GE producers whose fortunes turned overnight. But it was, in fact, Chinese policy that ultimately propelled the two companies to aim for the stars.

Which country is the largest producer of graphite electrodes?

In 2017, China was the biggest producer and consumer of Graphite Electrodes, followed by the European Union and Japan. Back in India a humble manufacturer of Graphite Electrode was trying to turn the tide.
