Understanding the Role of Morphology in the Direct Synthesis of Diethyl Carbonate Over Ceria‐Based Catalysts: An In Situ Infrared and High‐Resolution TEM Study

ChemCatChem, EarlyView.
Pure and Zr‐doped ceria‐based catalysts with different morphologies were developed for the direct synthesis of diethyl carbonate from ethanol and CO2. Rod‐shaped pure CeO2 outperformed the other samples, thanks to abundant structural defects and high basicity.

Cannabigerol Extraction from a Cannabis Cultivar Using a Supercritical Carbon Dioxide Process

Chemical Engineering &Technology, EarlyView.
The aim of this work was to assess for the first time the supercritical fluid extraction (SFE) process feasibility to obtain a CBG‐rich extract from Cannabis. Extraction experiments highlighted that CBG can be properly extracted at 18 MPa and 40 °C and the extraction plant scheme affected CBG recovery and purity.

Development and Validation of a Laboratory‐Scale Methanol Synthesis Mini‐Plant and Digital Twin Simulation

Chemie Ingenieur Technik, EarlyView.
A methanol mini‐plant and its digital twin were developed to study flexible feedstocks, reactant recycling, and product condensation. Experimental results show good agreement with simulations, allowing systematic investigation of process parameters. Tests with biomass‐derived syngas demonstrated the feasibility of industrial COx sources.

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

The 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.

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 ...

Reaction Calorimetry in Supercritical Carbon Dioxide

Macromolecular Materials and Engineering, 2004
AbstractSummary: Reaction calorimetry is an efficient tool used to obtain kinetic, thermodynamic and safety data. A reaction calorimeter, RC1e‐HP350, developed in collaboration with Mettler‐Toledo GmbH, allows investigating chemical reactions under supercritical conditions. The main technical difference, compared with a classical liquid system, is that

Evaluation of the CO2 storage potential in CO2‐enhanced oil recovery: A case study of the Subei Basin, Jiangsu Province, China

Deep Underground Science and Engineering, EarlyView.
CO2‐enhanced oil recovery (CO2‐EOR) is an economically viable carbon capture, utilization, and storage (CCUS) technique that is widely practiced and contributes significantly to the achievement of carbon‐neutral cities. However, few studies have been conducted on CO2‐EOR source–sink matching involving different emission sources, different carbon ...

Supercritical Carbon Dioxide Extraction

, 2019
The objective of this thesis is to explore the properties of supercritical carbon dioxide (CO2). In addition, the feasibility of building a small-scale low cost system will be explained. A supercritical fluid is a fluid which exhibits properties between liquid and gas with liquid like densities and viscosities similar to a gas.
