Effect of the additive concentration on the modification of petroleum coke and anode quality

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

The Canadian Journal of Chemical Engineering, EarlyView.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

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.

Transient thermal modelling of green anode cooling in the aluminium industry

The Canadian Journal of Chemical Engineering, EarlyView.
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before

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.

Bridging Inter‐Organizational Collaboration, Circular Economy Practices, and Firm Performance: The Role of Dynamic Capabilities Within Baltic States

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite the growing interest in the circular economy (CE) among various stakeholders, several research gaps continue to challenge researchers and practitioners, specifically among emerging European economies. This study analyzes survey data from 127 manufacturing SMEs in the Baltic states.

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.
