Relevance of the composition of municipal plastic wastes for metallurgical coke production [PDF]

, 2011
This study is concerned with the effects of the composition of mixed plastic wastes on the thermoplastic properties of coal, the generation of coking pressure and the quality of the resulting cokes in a movable wall oven at semipilot scale.

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

Strain‐based modeling and analysis for rock blasting and geomechanics applications

Deep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

An optimizing microseismic method for rock burst early warning based on mining production process

Deep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Experimental studies of self-sustaining thermal aquifer remediation (STAR) for non-aqueous phase liquid (NAPL) sources [PDF]

, 2008
Self-sustaining Thermal Aquifer Remediation (STAR) is a novel technology that employs smouldering combustion for the remediation of subsurface contamination by non-aqueous phase liquids (NAPLs). Smouldering is a form of combustion that is slower and less

Synthesis of Coal Tar‐Based Hypercrosslinked Polymers via Friedel‐Crafts Alkylation: An Efficient Way to Access Carbon Electrode Material for Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid coal tar (CT) is synthesized into hypercrosslinked polymers (HCPs) via the Friedel–Crafts alkylation, followed by oxidation‐carbonization to form disordered microporous carbon. The resulting CF2CT exhibits a high three‐electrode specific capacitance of 342 F g−1 at 1 A g−1, and the assembled symmetric supercapacitor illuminates a light sign ...
