The Pd-promoted Ni-Co bimetallic catalysts were prepared using ultrasonic-assisted impregnation, and their performance was subsequently assessed in a fixed-bed reactor. The catalyst's performance was evaluated in glycerol dry reforming (GDR) over a range of temperatures, from 873?K to 1173?K and reactant partial pressures ranging from 10?kPa to 40?kPa. The results indicated that as the temperature

Spray towers to can be used to absorb pollutants gases. Due to the complexity of the process, to propose mathematical models for prediction of removal efficiency and volumetric mass transfer coefficient, is a difficult task. This work aimed to evaluate the influence of variables on the SO2 removal process in a spray tower and to obtain an artificial neural network (ANN) to predict the removal efficiency

Thermal dehydration process is an indispensable unit operation involving most of the fields in industry. Driven by the imperious demands in energy consumption reduction and quality improvement, we developed a coupling catalytic dehydration strategy, in which the water in the chloride hydrate was directly used as the reactant to participate in water–gas shift reaction. The autocatalytic process is depended

Batch processes in manufacturing industries often adapt new products to meet the changing market demands. Dynamic modeling with limited data for new products may lead to inaccurate results. One solution is to extract useful knowledge from historical production data that can be applied to the new grade. However, past historical data from different product grades are often imbalanced. In this study,

Gas-liquid multiphase process occupies a significant part in the chemical industry, and the emerging gas–liquid microfluidic technology provides a highly efficient and controllable tool for gas–liquid systems such as chemical product synthesis, gas separation, and environmental protection. To point out the microscale gas–liquid multiphase process from the fundamental study to its utilization, this

In a pulsed compression reactor (PCR) experiments were done with N2O (4%mol), CH4 (1%mol) and CO2 (2%mol) diluted in the inert gases Xe, Ar, Ne and He. The mixtures were compressed up to 250 bar, reaching temperatures of up to 4000 K. At equal temperature, pressure and volume, significant differences (up to 20%) were measured in the conversion of the three species in different noble gases. The measurements

To enhance the availability and accessibility of medical oxygen in local hospitals in Morocco, a solid approach has been conducted for upscaling PSA unit. This comprehensive research involves the design, simulation, and performance evaluation of the PSA unit to confirm the functioning and efficiency of the system. The design phase meticulously considers hospital oxygen requirements, utilizing data

Ni-Co bimetal catalysts showed the resistance to carbon deposition in DRM, and Co segregation on Ni surface plays very important role, but the underlying mechanism remains unclear. Hence, in current research, Ni and Ni-Co bimetal catalysts were prepared, and fixed-bed tests, characterizations and DFT calculations were carried out to uncover the effect of doped Co on the carbon formation and elimination

Mixed matrix membranes (MMMs) based on metal–organic frameworks (MOFs) are expected to realize efficient separation of CO2. However, interfacial compatibility issues between MOFs and polymer matrices limit their performance. In this work, a post-synthesis modification (PSM) strategy was adopted to convert UiO-66 into porous liquids (PLs). MMMs were prepared by incorporating PLs into PIM-1 matrix. The

The development of novel photocatalytic platform for efficient water purification and sterilization is of utmost importance due to the significant threat of chronic diseases resulting from water pollution and bacterial contamination. Herein, a high-efficiency, easy-recyclable, and environment-friendly photocatalytic fabric was developed as a water disinfection and organic pollutant degradation platform

The redox kinetics of the oxygen carriers are crucial in Chemical-Looping Combustion (CLC) systems. The random pore model (RPM) was widely used to investigate the macroscale redox kinetics of oxygen carriers in previous studies, in which the reaction rate constants were obtained just by fitting the experimental data. This study presents a first principle based rate equation (1pRE) applied to the RPM

The widespread use of petroleum-based plastics brings potential hazards to the ecological environment. In order to solve this issue, the development of biodegradable materials with both high mechanical, barrier performances and food safety is imminent.
