Energy‐Efficient Induction Carbonization: Tailoring Pore Structures in Hard Carbon Anodes Toward Enhanced Electrochemical Performance

open access: yesCarbon Energy, EarlyView.
ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Key technologies for low-carbon modern coal-based energy

open access: yesMeitan xuebao
Coal energy has made a significant contribution to the development of human industrialization, but coal energy is faced with the major problem of high carbon emissions. Modern coal-based energy is a new path to crack the contradiction between coal energy

Extended batch adsorber analogue model (e‐BAAM) for rapid evaluation of CO2 capture pressure swing adsorption cycles

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This work presents a simplified extended‐batch adsorber analogue model (e‐BAAM) to quantify key performance metrics such as purity, recovery, and energy trends for various pressure swing adsorption (PSA) process cycles for CO2$$ {\mathrm{CO}}_2 $$ capture.

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...
