A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

Purification of Zinc Oxide Using Direct Thermal Process by Petroleum Coke
Iraqi Journal of Chemical and Petroleum Engineering, 2009 The present investigation is concerned for the purification of impure zinc oxide (80-85 wt %) by using petroleum coke (carbon content is 76 wt %) as reducing agent for the impure zinc oxide to provide pure zinc vapor, which will be oxidized later by air ...

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking
The Canadian Journal of Chemical Engineering, EarlyView.Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Fatigue behaviour of coke drum materials under thermal-mechanical cyclic loading
Theoretical and Applied Mechanics Letters, 2014 Coke drums are vertical pressure vessels used in the delayed coking process in petroleum refineries. Significant temperature variation during the delayed coking process causes damage in coke drums in the form of bulging and cracking.

Investigation of the Effect of Thermal Shields on the Calcination of Petroleum Coke in Rotary Disc Kilns [PDF]
Due to various impurities, impure petroleum coke obtained during extraction processes is unsuitable for optimal use. The calcination process, commonly called coke baking, has gained considerable attention for its ability to purify coke and remove waste ...

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen
The Canadian Journal of Chemical Engineering, EarlyView.Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

Separation of Petroleum Coke from Anode Stubs Produced During the Aluminum Electrolysis
Iranian Journal of Materials Science and Engineering, 2019 Petroleum coke contains high amounts of carbon and is used in the manufacturing of anode electrodes for the aluminum extraction. In the process of aluminum production, some particles separate from anodes as waste which contain petroleum coke.

Kiln Firing of Fluid petroleum Coke
Materiales de Construccion, 1956 Las características del coque de petróleo –elevada capacidad calorífica, pequeña cantidad de materia volátil y pequeño contenido de cenizas- hacen adecuado su empleo como combustible. Realizando la cocción de forma adecuada se obtiene un clinker normal.
