Modelling rates of gasification of a char particle in chemical looping combustion [PDF]

Proceedings of the Combustion Institute, 2015
Abstract Rates of gasification of lignite char were compared when gasification with CO 2 was undertaken in a fluidised bed of either (i) an active Fe-based oxygen carrier used for chemical looping or (ii) inert sand. The kinetics of the gasification were found to be significantly faster in the presence of the oxygen carrier, especially at ...

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Operational Performance Implications of Circular Economy Implementation: An Empirical Exploration in the Manufacturing Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The global manufacturing sector has increasingly adopted circular economy (CE) practices to address sustainability challenges and improve operational efficiency. This study explores the impact of five CE practices—reduce, reuse, remanufacture, recycle, and recover—on key operational performance dimensions: quality, speed, dependability ...

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Steel converter slag as an oxygen carrier for chemical-looping gasification

Fuel Processing Technology, 2020
Abstract Chemical Looping Gasification (CLG) is a dual fluidized bed gasification technique where an oxygen carrier is used as bed material instead of sand. An optimized process could have several advantages, including i) one concentrated CO2 stream, amiable for carbon capture, ii) less tar formation, iii) additional reaction pathways for syngas ...

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production

Carbon Energy, EarlyView.
Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐
