Definition. Asphalt. A darkbrowntoblack cementlike material containing bitumens as the predominant constituent obtained by petroleum processing; used primarily for road construction. It includes crude asphalt as well as the following finished products: cements, fluxes, the asphalt content of emulsions (exclusive of water), and petroleum ...
The ratios were as follows: 35% was assigned to gasoline, 35% to diesel, and 30% to coke. To put all of the refinery's products on a liquid volume basis, the coker's petroleum coke was "converted" into a oil barrel energy equivalent at a ratio of metric tonnes of coke to barrels of actual liquid, as described in the Table 4 note ...
Calcined petroleum coke is used for the production of carbon anodes in the HallHéroult aluminum smelting process due to a combination of low impurity levels, ready availability, and relatively low cost. This article provides a review of the history and use of calcined petroleum coke for anode production and describes the different calcining technologies used by the industry. The article ...
Petroleum coke samples are original one and those heattreated at 1860, 2100, 2300, 2600, and 2800C (abbreviated to PC, PC1860, PC2100, PC2300, PC2600, and PC2800). First coulombic efficiency of petroleum coke varies depending on the heattreatment temperatures as given in Table [45,46,50].PC1860 and PC2100 give high first coulombic efficiencies, 8890%.

1. Introduction. Petroleum coke, or petcoke, is a carbon rich (>∼80 wt%) byproduct from oil refining and synthetic crude oil production (Hill et al., 2014; Miller, 2015) that has been largely stockpiled on site with global storage increasing at a rate of ∼6 million tonnes per year (Division, 2020).The petcoke in storage has become a major source of environmental pollutants including ...
A unit of volume equal to 42 gallons. A general classification for one of the petroleum fractions produced in conventional distillation operations. It includes diesel fuels and fuel oils. Products known as No. 1, No. 2, and No. 4 diesel fuel are used in onhighway diesel engines, such as those in trucks and automobiles, as well as off ...
Managing Shot Coke: Design Operation . by . John D. Elliott . Director, Refining and Coking . Foster Wheeler USA Corporation . Houston, TX, USA 77079 . INTRODUCTION . Delayed cokers that produce fuel grade petroleum coke are operated for best economic advantage to maximize the production of clean liquid products. When feedstocks for these ...
This study aims to determine the main adsorption mechanism by which chromium (VI) is adsorbed onto the surface of a petroleumcoke sourced activated carbon, a feedstock not prevalent in current literature. The study also aims to produce an activated carbon adsorbent that is both costeffective and efficient for the removal of chromium (VI) in neutral waters. The efficacy of thermallytreated ...
Gasification technology can convert highsulfur petroleum coke (petcoke) to highvalue syngas (CO + H 2) for hydrogen generation and chemical products via synthesis, it provides superior environmental performance in comparison to combustion since the sulfur inherent in petcoke can be converted into H 2 S, and then can be recovered as S by Claus process.
In this work, for the first time, we have not only synthesized activated carbon sheets with a surface area of 2394 m 2 /g from petroleum coke but also demonstrated the commercial applicability of petroleum coke derived activated carbon sheets by fabricating a cylindrical supercapacitor with the specifications of V and 1200 F, and the ...
Lowquality sulfur petroleum coke usually not widely qualified for use and is stockpiled at refineries around the world or used as solid fuel. One of the promising uses of lowquality petroleum coke is its physical or chemical activation in order to obtain a highly porous carbon material that can be used as a catalyst carrier, adsorbent, the basis for capacitive electrodes. In this work, four ...

Fluid Catalytic Cracking (FCC) is the conversion process used in petroleum refineries to convert the highboiling point, highmolecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products. [1] [2] [3] The cracking of petroleum hydrocarbons was originally done by thermal cracking, now ...
The petroleum industry and federal regulators characterize petcoke as a "coproduct" because it may have some commercial value as a boiler fuel and as a raw material in manufacturing. Nearly half of petroleum refineries employ "coking" processes. Refineries also produce petcoke as a byproduct of catalysis, which refineries later consume ...

Methodology. Key prices. Argus prices are used extensively by energy companies, governments, banks, regulators and other organisations as benchmarks for derivatives and as indexes in physical contracts. They are used as reference prices in physical supply and derivative contracts, for marktomarket purposes, as an indication of value for tax ...
The study claims that the catalytic steam reforming improved the chemical heat sink capacity by around 750 kJ/kg of RP3 fuel. It is also highlighted that the presence of the catalyst and steam together reduced the coke deposition rate from 148 μg/(cm 2 ·min) to μg/(cm 2 ·min). However, the individual effect of steam and the catalyst ...
Raw coke. Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the ...
