ChemCatChem, EarlyView.Chemical looping‐based dehydrogenation of ethane (CL‐ODH) is composed with reduction step of metal oxides by C2H6 dehydrogenation and CO2 activation on the partially reduced metal oxides. Stable preservation of active FeTiO3 phases on the rutile TiO2 phase was responsible for a superior CL‐ODH activity.

Density, viscosity, and stability of products from combinations of visbreaking and deasphalting
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Transporting bitumen through pipelines in Western Canada is cost intensive because the oil has to be diluted with light solvents to meet pipeline specifications. The diluent requirement can be reduced by visbreaking (VIS) and solvent deasphalting (SDA), each of which decrease the viscosity and density of the oil.

The 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.

Thermal degradation of impact‐modified PMMA in mechanical and chemical recycling
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Poly (methyl methacrylate) (PMMA) is a thermoplastic with outstanding tensile strength, UV resistance, and a high level of transparency that has been used widely for optical applications such as glazing in the automobile industry. Mechanical recycling, the most widespread method, degrades the physical properties and prevents reusing PMMA in ...
