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.

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.

Impurity Removal from Petroleum Coke

2016
The question of treating high-impurity coke to enable use in anodes was examined. A mineralogical analysis of different cokes demonstrated that more than 99 % of the particles contained the expected concentrations of sulfur, nickel, and vanadium while a small number of particles contained inclusions of other impurities.

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.

Pitch and petroleum coke additions to coke oven charges

The Canadian Journal of Chemical Engineering, 1980
AbstractSeveral pitch materials and a petroleum coke were added to coke oven charges in an attempt to make good metallurgical coke from Canadian coal of poor coking quality. Coal and petroleum pitches were added to a low fluid western Canadian coal of medium volatile bituminous rank, and the blends coked in a technical‐scale moveable wall test oven ...

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.

MICROSTRUCTURE OF PETROLEUM COKE AS CARBURIZER

2010
As a carburizer in foundries, regular quality petroleum coke is often used. The selection of a carburizer depends upon many factors, the most important of which are the microstructure. This paper investigates the microstructure of commercial petroleum coke with increasing sulphur content as potential carburizing material in iron-carbon alloys ...
