Conditions for the joint conversion of CO2 and syngas in the direct synthesis of light olefins using In2O3−ZrO2/SAPO-34 catalyst
(ACS, 2021-11-09)
The conditions for promoting the joint conversion of CO2 and syngas in the direct synthesis of light olefins have been studied. In addition, given the relevance for the viability of the process, the stability of the ...
Kinetic modeling and reactor design of the direct synthesis of dimethyl ether for CO2 valorization. A review
(Elsevier, 2022-08-04)
The direct synthesis of dimethyl ether (DME) is considered one of the most attractive routes for valorizing CO2 and syngas on a large scale. DME has a high cetane number and its properties are similar to those of liquefied ...
Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2
(2020-10-16)
A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, ...
ADITU: A mesh-free formulation for the solution of Helmholtz equation in bounded and unbounded domains
(Elsevier, 2022-06-01)
This work describes a mesh-free collocation formulation for the acoustic fluid–fluid coupling among
non-homogeneous bounded and unbounded fluid domains. The proposed formulations use series
of functions that are generated ...
New trends in catalysis for sustainable CO2 conversion
(MDPI, 2022-10-23)
Over the past few decades, there have been many advances in the world, leading to improvements in quality of life. Due to demographic and industrial growth, consumption has increased, as well as the amount of waste and ...
Automatic Identification Algorithm of Equivalent Electrochemical Circuit Based on Electroscopic Impedance Data for a Lead Acid Battery
(MDPI, 2021-06-06)
Obtaining tools to analyze and predict the performance of batteries is a non-trivial challenge because it involves non-destructive evaluation procedures. At the research level, the development of sensors to allow cell-level ...
Numerical Modeling of Face Shield Protection against a Sneeze
(MDPI, 2021-07-05)
The protection provided by wearing masks has been a guideline worldwide to prevent the risk of COVID-19 infection. The current work presents an investigation that analyzes the effectiveness of face shields as personal ...
A Hybrid Control Approach for the Swing Free Transportation of a Double Pendulum with a Quadrotor
(MDPI, 2021-06-13)
In this article, a control strategy approach is proposed for a system consisting of a quadrotor transporting a double pendulum. In our case, we attempt to achieve a swing free transportation of the pendulum, while the ...
Design and Implementation of a Maximum Power Point Tracking System for a Piezoelectric Wind Energy Harvester Generating High Harmonicity
(MDPI, 2021-07-09)
In this work, a maximum power point tracking (MPPT) system for its application to a new piezoelectric wind energy harvester (PWEH) has been designed and implemented. The motivation for such MPPT unit comes from the power ...
Temperature based maximum power point tracking for photovoltaic modules
(Nature, 2020-07-27)
In this article authors propose a temperature based Maximum Power Point Tracking algorithm (MPPT). Authors show that there is an optimal current vs maximum power curve that depends on photovoltaic (PV) module temperature. ...
