The petroleum coke is the main raw material for the preparation of pre-baked anode materials for aluminum electrolysis. However, the presence of vanadium in petroleum coke negatively affects its properties. In the present study, microwave-ultrasonic assisted leaching is used to enhance the removal of vanadium from petroleum coke.
Removal of sulfur from metallurgical coke. III. Coking coal with the addition of inorganic substances. [Effectiveness of addition of NaCl, MgO, MgCO/sub 3/, iron ore, CaCO/sub 3/, and CaO before coking]
Petroleum coke calcining systems. Petroleum coke calcining is thermal treatment of green petroleum coke to beneficiate the material by removing moisture and volatile matter, while increasing density and decreasing electrical resistivity.
300W Laser cleaning machine is a new generation of surface cleaning high-tech products. It have below features:1)Free maintenance, high cost effective, low cost. 2)Forced air cooling, high stability of continuous using. 3)Good laser beam mode, wide range metal application 4)Without.
The petroleum coke component is a hydrocarbon containing 90-97% carbon, 1.5-8% hydrogen, and nitrogen, chlorine, sulfur and heavy metal compounds. Petroleum coke is a by-product of the delayed coking unit's feedstock oil cracking at high temperatures to produce light oil. The production of petroleum coke is about 25-30% of the feedstock oil.
Petroleum coke refers to all types of carbonaceous solids obtained in petroleum processing, which includes green or raw, calcined and needle petroleum coke. Petroleum coke is used in many applications, including electrodes and anodes. It is also used as a fuel in the metal and brick industries.

May 29, 2015· Petroleum coke, or petcoke, is a granular coal-like industrial by-product that is separated during the refinement of heavy crude oil. Recently, the processing of material from Canadian oil sands in U.S. refineries has led to the appearance of large petcoke piles .
9 Claims. (Cl. 196-40) This invention relates to the treatment of crude petroleum and petroleum oils to efiect the removal of metal contaminants. Petroleum commonly contains small quantities of heavy metals, such as vanadium, nickel, iron, chromium and molybdenum. These heavy metals presumably occur in petroleum as compounds.
How it works. Coke calcining plants can be located in oil refineries, captive plants in aluminum smelters or merchant plants. Rotary Kiln The petroleum green coke is fed into a refractory lined rotary kiln where the volatiles are driven off during the calcining process in an oxygen deficient atmosphere.
A common product which contains Phosphoric Acid is Naval Jelly. The soft drink Coca-Cola contains Phosphoric Acid, so Coke will etch rust. But Coke also contains carbonic acid and other nasty things. You're going to drink that stuff? Auto body shops treat metal with acid metal wash, a solution of Phosphoric Acid and alcohol before painting.

Petroleum coke is produced by coking liquid petroleum residues and pitches in metal coke vats or special furnaces. Petroleum coke is also formed during cracking and pyrolysis of products of petroleum distillation. Pitch coke and petroleum coke are the main raw material for producing electrodes.
Let it soak for 24 hours. If the item is too large to submerge, like a bathtub with rust spots, for example, simply saturate a scrubbing sponge with the cola and scrub the rust stain. A crumbled piece of aluminum foil dipped in Coke removes rust from chrome bumpers, motorcycles and .
Green petroleum coke is a carbonaceous solid residue produced by the thermal decomposition of petroleum fractions.It has low metal content and is calcined in rotary kilns to form calcined petroleum coke.During the calcination process, green petroleum coke is heated to increase its electrical conductivity and remove volatile matter, moisture, and other impurities.The calcined petroleum coke .
