Investigation of internal phases of linear SBS modified bitumen at the nanoscale using AFM PF-QNM

Journal of Traffic and Transportation Engineering (English ed. Online), 2023
Currently, few studies explore the internal phases of styrene-butadiene-styrene (SBS) modified bitumen at the nanoscale, though the surface phases of SBS modified bitumen have been deeply understood through a lot of research.

Study on the Synergistic Effects and Optimization of Flotation Reagent Blends Under Low Reagent Consumption

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

Separation and Recovery of Bitumen from Oil Sand by CO2 Desorption of Amine Solution

Journal of MMIJ
Bitumen extracted from oil sand has garnered increasing attention as an alternative energy source for fossil resources. Since oil sand consist of a mixture of bitumen (10-15 wt. %), water (4 wt. %), and sand (80 wt.

The Effect of Demineralization on Coal Functional Group Pyrolysis: Rank‐Dependent Dual Mechanisms of Structural Reorganization and Mineral Catalysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

Advanced Investigation of the Elimination of Methylene Blue From Wastewater Using Activated Carbon–Copper Oxide Nanowires: New Perspectives With Statistical Physical Modeling

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the actual route of methylene blue (MB) dye adsorption by using fabricated polyfunctional activated carbon–copper oxide nanowires (AC@CuO‐NWs) from bulky wastewater bodies has been investigated. To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical ...

Effect of Temperature and Atmosphere on Agglomeration of Bed Particles in a Bubbling Fluidised Bed Burning Na‐Enriched Coal

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised
