Finite element modelling of multisolute activated carbon adsorption

Flexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

Activated Carbon Adsorption

Hydrogen Adsorption on Activated Carbon

The adsorption of hydrogen on carbon nanotubes and activated carbons has generated considerable interest in relation to hydrogen storage for fuel cells applications[1-3]. However, the widespread use of hydrogen as a fuel is limited by the lack of a convenient and cost-effective method of hydrogen storage. Adsorption of supercritical hydrogen is limited by the low interaction energy between hydr...

Finite Element Simulation of Corn Moisture Adsorption

Thin-layer moisture adsorption tests were conducted by exposing com kernels to different air relative humidities (RH of 75, 80, and 90%) and temperatures (25, 30, 35, and 40°C). A two-dimensional finite element model was developed to simulate moisture diffusion into a com kernel during adsorption. The finite element model satisfactorily predicted experimental moisture ratio of corn samples and ...

Reduction of Adsorption Capacity of Activated Carbon

In occupational hygiene, activated carbon produced from coconut shell is a common adsorbent material for harmful substances including organic vapors due to its outstanding adsorption capacity and cost advantage. However, moisture adsorption of the carbon generally decreases the adsorption capacity for organic vapors. In a previous report, we prepared several coconut shell activated carbons whic...
