Telegram. Petroleum coke, also known as petcoke is a byproduct of the refining process of crude oil. It is a carbon-rich solid material that is used for various industrial and commercial purposes, such as fuel in power plants and cement kilns. Petcoke can vary in appearance from black, to dark grey, to golden brown, depending …

1. Fuel – Almost 80% of the worldwide Petcoke production is "Fuel-grade," which is used to generate electricity and in cement furnaces. 2. Paint And Colourings – Calcined Petcoke is used to make titanium dioxide or TiO2. It is a mineral that substitutes harmful lead in paints. It is also used as a pigment in sunscreens and colourant in food and plastics.

Petroleum coke, or petcoke as it is commonly known, is a by-product of petroleum refining. Petcoke refers to all types of carbonaceous solids obtained in petroleum processing which includes green (raw), calcined and needle petroleum coke. Petcoke is used in many applications, including electrodes and anodes.

Cadmium is a toxic metal with no known biological function. It is increasingly important as an environmental hazard to both humans and wildlife, and it exemplifies the double edged nature of many toxic substances. Thus, on the one hand cadmium can act as a mitogen, stimulate cell proliferation, inhibit apoptosis, inhibit DNA repair, and promote ...

Cadmium uptake by plants is greater in saline soils or soils irrigated with water containing high chloride levels (McLaughlin et al., 1999 ). Therefore, testing irrigation water to determine chloride levels and understanding soil salinity is crucial to minimizing cadmium uptake in crops and the food supply (Figure 3 ).

Smoking 20 cigarettes per day causes the increased absorption of cadmium, and the content of cadmium in tobacco leaves ranges from 1 to 2 μg × g −1 …

Cadmium levels in the kidney were significantly higher (p < 0.05) in females than those in males for both species. As regards to Pb, the highest concentrations were detected in the liver (3.45 mg ...

1. Industry Description. Titanium Dioxide (TiO2) is a metal oxide commonly used as a white pigment in paint manufacturing, paper, plastics, rubber, ceramics, fabrics, floor covering, ink, and other applications (IPCC 2006). The majority of titanium dioxide production is for the manufacturing of white paint.

The Platts monthly US CPC assessment rose slightly to $230-$245/mt FOB US Gulf ports from $225-$245 in March, reflecting transactable value for CPC with max 3% sulfur, 300-400 ppm vanadium and typical metals . Prices on Q1 contracts ranged from $220-$250 FOB Gulf. A calciner reported offering on three spot cargoes for Europe, South America and ...

2.1. Aquatic Organisms. Petcoke is a hardened residuum of mostly carbon, and is therefore poorly soluble in water. Nonetheless, Baker et al. [] detected elevated levels of nickel in water from constructed wetlands using petcoke and consolidated tailing waste materials in Alberta, Canada.Furthermore, this study found statistically insignificant …

The occurrence modes of V in raw petcoke and their gasification residues were determined using the method of sequential chemical extraction. With increasing gasification temperature, staged ...

Cadmium levels are higher in liver and kidney than in muscle and older animals 63. Average cadmium in the liver and kidney of wild moose was 2.11 and 20.2 μg/g wet …

The petroleum industry and federal regulators characterize petcoke as a "co-product" because it may have some commercial value as a boiler fuel and as a raw material in manufacturing. Nearly half of U.S. petroleum refineries employ "coking" processes. Refineries also produce petcoke as a by-product of catalysis, which refineries later …

Petcoke ash contains high levels of vanadium (V), nickel (Ni), iron (Fe) and calcium (Ca). The chemical composition of ash plays an intrinsic role in determining ash fusibility. To better ...

Petroleum coke is high in carbon—this makes it chemically similar to coal and both energy dense and useful for many other industrial processes that require carbon. About 80 percent of petcoke is used as fuel. While petcoke is similar to coal, petcoke generates just 0.2 percent of America's electricity, while coal generates nearly 40 percent.

Specifically petroleum coke (petcoke), a by-product of the oil refining process. And specifically anode-grade petcoke, commonly defined as that with a sulfur content of less than three percent.

Petcoke had a high fuel ratio (8.7), high sulfur (7 wt%), and low ash content (0.86 wt%). • Petcoke showed slower pyrolysis reaction, higher ignition temperature, and …

Cadmium is a heavy metal present in certain foods and cigarette smoke. People who work in professions like mining are at an elevated risk of cadmium exposure. Find out what the health effects of ...

Raw (or green) coke contains 0.5-1% nitrogen and 0.2- 6.0% sulfur, which become emissions when coke is Calcined. Heating Value: Petroleum coke is highly combustible and has a high heating value, often between 8,000 and 10,000 BTU/lb. Size: The particle sizes of petcoke are typically in the range of 0-50 mm.

Abstract. Cadmium (Cd) is a ductile metal in the form of a blueish or silvery-white powder. It is naturally found in soil (about 0.2 mg/kg), minerals, and water. Cd belongs to the group of toxic, carcinogenic, and stimulating elements. Its biological half-life in the human body ranges from 16 to even 30 years on average.

Petcoke is rich in carbon; hence, it will yield high concentration of syngas (a mixture of hydrogen and carbon monoxide) in the total gaseous product. This syngas can be used to generate electricity or produce liquid fuels or chemicals. In this chapter, petcoke gasification technology and the associated issues and challenges are discussed. ...
