Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Supercritical Fluids Extraction of Fatty Acids from Spent Coffee Grounds

, 2014
Nowadays, the better utilization of wastes from different technological productions is a key factor for the economical and the environmental issues. The easiest solution is often the choice of their incineration in order to produce energy.

Obtaining β-caryophyllene From Cordia Verbenacea De Candolle By Supercritical Fluid Extraction

, 2015
In the present work, the use of supercritical fluid extraction (SFE) to obtain β-caryophyllene from Cordia verbenacea DC was studied. The assays were performed using a single-step SFE (1S-SFE) and a three-step SFE (3S-SFE).

Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Conventional and RAFT dispersion copolymerizations of HEMA and EGDMA in supercritical CO2 are compared in terms of swelling index (crosslink density), morphology, particle size distribution, and modular differential scanning calorimetry. Abstract The syntheses of net‐poly((2‐hydroxyethylene methacrylate)‐co‐(ethylene glycol dimethacrylate ...

Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity

CleanMat, EarlyView.
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Improvement of the dissolution of the antineoplastic drug regorafenib through impregnation into pullulan polysaccharide using supercritical fluid technology: Optimization of the process

Journal of CO2 Utilization
Regorafenib is administered orally for the treatment of metastatic colorectal cancer. However, its limited water solubility hinders its clinical efficacy. This study explores the impregnation of regorafenib monohydrate (REG MH) into pullulan (PULL) using
