Corn cob pyrolysis: A systematic literature review of methods and applications

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Trade‐offs in stability and activity: A study of ordered mesoporous alumina and γ‐Al2O3 supported Ni catalysts for CO2 methanation

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
CO2 methanation over Ni‐K alumina catalyst synthesized via evaporation‐induced self‐assembly to prepare ordered mesoporous alumina (Ni‐K‐OMA) catalysts and via incipient wetness impregnation (Ni‐K/Al2O3). Ni‐K‐OMA exhibited higher CH4 selectivity while Ni‐K/Al2O3 had a higher TOF.

Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

open access: yesChemPlusChem, EarlyView.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated
