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.

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

open access: yesEcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.
