Modelling of methanol synthesis in a network of forced unsteady-state ring reactors by artificial neural networks for control purposes [PDF]

, 2004
A numerical model based on artificial neural networks (ANN) was developed to simulate the dynamic behaviour of a three reactors network (or ring reactor), with periodic change of the feed position, when low-pressure methanol synthesis is carried out.

Continuous Production of Biodiesel with Supercritical Methanol: a Simple Compressible Flow Model for Tubular Reactors [PDF]

, 2011
From an industrial point of view, the continuous process for biodiesel production with supercritical methanol (SCM) is more appropriate than the batch process.

Innovative Methanol Synthesis Process by Using Exergy Recuperative Pressure and Heat Circulation Modules

Chemical Engineering Transactions, 2017
The demand for methanol will continue increasing methanol is attractive as fuel applications and chemicals. To reduce energy requirements for the methanol synthesis, it is necessary to investigate a whole process and to retrofit it with energy saving ...

Investigating the reaction mechanism of dimethyl carbonate synthesis through isotopic labeling experiments

Catalysis Communications, 2023
The synthesis of dimethyl carbonate (DMC) from carbon dioxide and methanol was studied over a ceria- zirconia mixed metal oxide. When using oxygen-18 labeled ceria-zirconia, no oxygen-18 labeled DMC or water was observed.

Kinetic Modeling of Series Reaction CH4-CH3OH-DME with CuO-ZnO/-Al2O3 Catalyst

Jurnal Bahan Alam Terbarukan, 2018
A kinetic model was proposed for the synthesis of methane to be dimethyl ether (DME) in one reaction step from (CH4 + O2) and (CH3OH) to dimethyl ether using kinetic CuO-ZnO /Al2O3 catalyst parameters.

New black indium oxide—tandem photothermal CO2-H2 methanol selective catalyst

Nature Communications, 2022
Harsh reaction conditions are generally required for CO2 hydrogenation to shift the thermodynamic equilibrium towards methanol synthesis. Here, a new black indium oxide with two types of active sites, frustrated Lewis pairs and oxygen vacancies, is ...

Fluid phase equilibria of the reacting mixture in the dimethyl carbonate synthesis from supercritical CO2 [PDF]

, 2003
In order to investigate the dimethyl carbonate synthesis from methanol and supercritical CO2, the thermodynamic behaviour of the reacting mixture, i.e. the quaternary methanol/CO2/DMC/water mixture, has to be known.

Valorizing Steelworks Gases by Coupling Novel Methane and Methanol Synthesis Reactors with an Economic Hybrid Model Predictive Controller

Metals, 2022
To achieve the greenhouse gas reduction targets formulated in the European Green Deal, energy- and resource-intensive industries such as the steel industry will have to adapt or convert their production.
