Chemistry – A European Journal, EarlyView.Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Methanol With Increased Water Content in Internal Combustion Engines
Chemie Ingenieur Technik, EarlyView.This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower
The Canadian Journal of Chemical Engineering, EarlyView.Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Demulsifying agent simplified model for offshore oil wells
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This article addresses key challenges in offshore petroleum production caused by multiphase flow instabilities, such as slug flow and emulsion formation. Traditionally, severe slugging is mitigated by increasing wellhead backpressure through partial choke valve closure. In this context, a simplified dynamic model—the fast offshore wells model (

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

Non‐monotonic jet pinch‐off induced by droplet impact on immiscible liquids
Droplet, EarlyView.The graphical abstract shows the evolution of the central jet following droplet impact and summarizes the non‐monotonic dependence of the critical Weber number on the dimensionless film thickness and Ohnesorge number. Abstract Droplet impact on immiscible liquids can generate a central jet whose pinch‐off behavior plays a crucial role in many advanced ...
