Desulphurization of petroleum coke by butagas

Fuel, 1973
Abstract The work described concerns the desulphurization of Egyptian petroleum coke by butagas in a fixed-bed reactor. Optimum values for reaction temperature and coke particle size were observed; but increased gas flow rate, prolonged reaction time, and decreased coke bed depth all favoured increased sulphur removal throughout the ranges studied ...

Desulfurization of petroleum coke: a review

Industrial & Engineering Chemistry Research, 1992
A number of processes ranging from purely physical such as solvent extraction to thermal or chemical treatment using different agents including hydrocarbon gases, alkali metal compounds, and hydrogen have been proposed for petroleum coke desulfurization.

Abradability of petroleum pyrolysis cokes

Chemistry and Technology of Fuels and Oils, 1987
Sample preparation and testing procedures were evaluated for determining the abradability of petroleum pyrolysis coke in its use as a filler for carbonaceous construction materials and for establishing coke grade based on abrasion resistance. Weight loss during abrasion was recommended as the test measurement.

The characterization of petroleum coke

Carbon, 1996
The characterization of both green, or uncalcined, and calcined petroleum coke filler is described utilizing known, standard test procedures to obtain the necessary data needed to characterize a candidate coke. Shortcomings in evaluating an uncalcined coke in the laboratory are also discussed.

Petroleum additives for coking batch

Coke and Chemistry, 2014
At OAO Gubakhinskii Koks, the influence of the content of coking additive in the batch on the operation of coke battery 2 is studied experimentally. The goal is to determine the maximum permissible content of petroleum additive in the batch for improvement in battery performance.

Analysis of Taiwan Petroleum Coke

Journal of the Chinese Chemical Society, 1963
AbstractPetroleum cokes, made from gas oil fraction of crude oil produced in different oil fields in Taiwan, were analyzed in ppm level for boron, vanadium, titanium, iron, calcium, aluminium, magnesium, chromium, cobalt, manganese, nickel, molybdenum, and copper.

Desulfurization of Egyptian Petroleum Coke

Developments in Chemical Engineering and Mineral Processing, 2003
AbstractFerric chloride and benzene were examined with many other chemicals to be used as solvents for the sulfur‐bearing compounds present in the Egyptian petroleum coke. The best results were obtained when ferric chloride and benzene were used consecutively, and more than 35% degree of desulfurization was obtained in this case.

Petroleum coke gasification: A review

The Canadian Journal of Chemical Engineering, 2013
AbstractThe production of petroleum coke (petcoke) in the refineries is progressively peaking up because of the trend of processing heavy crudes and in turn, a renewed interest in delayed coking process. Therefore, an efficient, economical, and environmentally safe utilisation of petcoke has become imperative in the current petroleum refining scenario.

Adhesion in coking petroleum resids

Chemistry and Technology of Fuels and Oils, 1987
A laboratory unit consisting of a reactor with loosely fitting rods was used to assess adhesion in coking petroleum resids. The relationship between adhesion and the temperature at which cracked tars are coked was determined. Adhesion as a function of temperature in coking straight-run resids with and without asphaltenes was assessed.
