Chemical Commodities via Pyrolysis of Biomass: Phase Equilibria Calculations to Develop Valorization Strategies

Chemie Ingenieur Technik, EarlyView.
This study exploits phase equilibria calculations to describe fundamental behavior of fast pyrolysis bio‐oil during recovery (condensation) and downstream fractionation (extraction). This information is combined with an overview of potential value chains to produce chemicals via biomass fast pyrolysis to assess strategies and synergies.

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

The 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

The 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.

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 ...
