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

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.

A systematic approach for identifying drivers of critical safety and establishing their hierarchy

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Learning from incidents is a crucial step in preventing and mitigating adverse events. Incident databases offer valuable insights for safety management improvements by cause and contributing factors. However, extracting meaningful information from incident investigation reports poses a significant challenge. This study introduces a data‐driven

A class of directed acyclic graphs with mixed data types in mediation analysis

Canadian Journal of Statistics, EarlyView.
Abstract We propose a unified class of generalized structural equation models (GSEMs) with data of mixed types in mediation analysis, including continuous, categorical, and count variables. Such models extend substantially the classical linear structural equation model to accommodate many data types arising from the application of mediation analysis ...

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

ChemPlusChem, 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
