In order to refine heavier oils, the 'coking' process was patented in 1913 in order to make more high-value transport fuels out of the 'bottom of the oil barrel.' Wringing out more liquids using coking, however, results in a solid residue called petroleum coke, or 'petcoke.' The heavier the oil, the more petcoke produced.
In summary, coal and oil analysis are valuable application fields for LIBS. In turn, the triumphantly application of LIBS for coal and oil will facilitate this technique to other fresh fields. 3.2. Environmental monitoring. Soil is vital to ecosystem, and it plays a significant role in agriculture and human survival and development.
Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.

Petroleum coke (petcoke), a by-product of petroleum refining that is high in contaminants, has quietly emerged in China as an inexpensive, but very dirty, alternative to coal. A …
As fossil fuels gradually deplete, oil shale, one of the world's largest energy resources, has attracted much attention. Oil shale semi-coke (OSS) is the main byproduct of oil shale pyrolysis, which is produced in large quantities and causes severe environmental pollution. Therefore, there is an urgent need to explore a method suitable …
Petroleum coke (PC)-derived porous carbons were developed through chemical activation using KOH and applied to adsorb Cu(II) ions from aqueous solutions. The effects of KOH/PC mass ratio and activation temperature on the preparation and physical properties of porous carbon were studied. Also, the effects of the initial solution …
1. Introduction. With the economic growth and the increasing demand, the production of petroleum coke, an important by-product from the coking process of residual oil, has increased rapidly [1].Due to some physical and chemical characteristics of petroleum coke such as high carbon content and high heating value, combustion is the …

What is Petroleum Coke? Generally, people think of oil refineries as producing gasoline and diesel fuel, but refineries produce much more than just those two fuels. One important product produced by refineries is something called petroleum coke, or "petcoke." Petcoke is used as a fuel and as a source of carbon for industrial processes. …
Usually, businesses produce activated carbon (AC) from finite resources like coal, lignite, peat, and petroleum byproducts, which can incur high costs and necessitate elaborate regeneration processes [26]. By 2018, the demand for activated carbon had surged to reach 2.1 million metric tons [27]. Due to this escalated demand and …
The chemistry and petrology of fly ash are controlled by a number of factors: (1) chemistry of the feed coal (and added fuels, such as petroleum coke, tires, biomass, etc.), (2) particle size of the fuel feed (controlled by pulverized fuel vs. cyclone combustion, maintenance of pulverizers, etc.), (3) design of the boiler and pollution-control system, and (4) …
