Carbon dioxide adsorbent is an important factor in the adsorption process of carbon dioxide. Therefore, this study interested in the adsorption of potassium carbonate solid sorbents on gamma-alumina to adsorb carbon dioxide. The added basic solution was used instead of the de-ionized water by...

Chemical looping combustion (CLC) is a technique for separating carbon dioxide from flue gas. It consists of two main processes: a fuel reactor and an air reactor. In the fuel reactor, fuel reacts with solid metal oxide particles to produce heat, CO2 and H2O vapor which later can be easily...

Nowadays, the global warming is considered as a world problem because it influences the environment by increasing the average temperature of earth surface. One of the greenhouse gases that release from human activities and fossil fuels combustion in industry is CO2. Several technologies are...

The core–shell structure of Nicore–Ptshell nanoparticles (NPs) was synthesized by a polyol method using 1,2 propanediol. The effect of using a different stabilizer, namely either polyvinylpyrrolidone or oleic acid, was investigated. The results revealed that the two stabilizers...

The road testing and demonstration of a three-wheeler vehicle driven by a 5 kW proton exchange membrane fuel cell (PEMFC) was carried out in the absence and presence of lead acid batteries. Prior to integrating the PEMFC module and batteries in the three-wheeler, they were tested and...

This research was carried out to prepare high performance membrane electrode assemblies (MEAs) for a proton exchange membrane fuel cell (PEMFC). The MEAs were prepared by introducing a microporous sublayer (MPS) between the gas diffusion layer and the catalyst layer. Main parameters for MPS...

This work aimed to characterize and optimize the variables that influence membrane electrode preparation using a design of experiment (DOE) approach in two steps. First, in the process of electrode preparation, the quantity of PTFE and drying time were found to have no significant influence...
