An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Knowledge Sharing in the Mining Sector: Unlocking Employee Ambidexterity Through Psychological and Environmental Mediating Factors

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how and why individual knowledge sharing fosters ambidextrous behavior among nonmanagerial employees in an operationally intensive, environmentally sensitive industry. We conducted a survey of 243 operators across 10 plants of an international lime producer, finding that knowledge sharing is positively related to individual

Zeolite deactivation during hydrocarbon reactions: characterisation of coke precursors and acidity, product distribution [PDF]

open access: yes, 2008
The catalytic conversion of hydrocarbons over zeolites has been applied in large scale petroleum-refining processes. However, there is always formation and retention of heavy by-products, called coke, which causes catalyst deactivation. This deactivation

Precision Synthesis of Biomass‐Derived Graphene‐Like Carbon With Tailored Crystallinity via Controlled Flash Joule Heating

open access: yesCarbon Energy, EarlyView.
A dual‐phase flash Joule heating strategy converts pre‐pyrolyzed biomass into structurally tunable carbon materials from waste feedstocks. By decoupling current‐driven thermodynamic input and duration‐dependent kinetic relaxation, the process maps the transition from amorphous carbon to few‐layer turbostratic graphene and turbostratic nanographite ...

REDUCING POWER PRODUCTION COSTS BY UTILIZING PETROLEUM COKE [PDF]

open access: yes, 1999
Petroleum coke, a byproduct of the petroleum-refining process, is an attractive primary or supplemental fuel for power production primarily because of a progressive and predictable increase in the production volumes of petroleum coke (1, 2).
