Granular Bed Filtration of Coal Pyrolysis Gas: Effects of Media Reactivity on Dust Removal and Products

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Granular bed filtration is a promising technology for removing dust from high‐temperature coal pyrolysis gas. In this work, the reactivity of coal pyrolysis products over ceramsite, char, ultrastable Y‐type (USY) zeolite, and quartz particles was compared.

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

The application of biomass ashes in sewage sludge management – a SWOT analysis

E3S Web of Conferences, 2018
Biomass plays an important role amongst renewable energy sources and for this reason, it is sometimes called as “future fuel”. According to different statistics, the share of biomass in renewable energy production is in excess of 50% and rising. The main

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

3‐Reactor Chemical Looping System for Point Source CO2 Capture and Subsequent Conversion for Liquid Fuel Production

EcoEnergy, EarlyView.
This study presents a novel 3‐reactor chemical looping system for CO2 capture and subsequent utilization with biomass and natural gas for producing liquid fuels. Using Ca2Fe2O5\Fe2O3 oxygen carriers, it achieves 60% CO2 capture efficiency, ∼80% syngas purity, and autothermal operation, offering a scalable, carbon‐negative route to sustainable fuels ...
