Methane Uptake

Potential agro wastes (i.e palm kernel shell and coconut shell) for producing low cost activated carbon (AC) was investigated. In this study, the activated carbon was produced by carbonization, chemical impregnation with KOH and microwave irradiation. The pyrolysis was carried out at 700 °C in an inert environment for 2 h. Microwave activation was carried out at 400W for 6 minutes. Characteristics of the material were investigated using Fourier transform infrared spectroscopy (FT-IR) analysis and scanning electrode microscopy (SEM). Methane adsorption equilibrium data on the activated carbons produced were obtained using static volumetric method. Microwave palm shell activated carbon (MPAC) and microwave coconut shell activated carbon (MCAC) recorded highest methane uptake of 2.489 and 1.929 mmol/g at 3 bar, 30°C. The adsorption data were correlated with Langmuir and Freundlich isotherms. The results shows that microwave activated carbon from palm shell and coconut shell have good methane adsorption characteristics.

There is increasing research on the adsorption of lead because its use in industrial processes has resulted in various forms of environmental contamination and negative human health issues. Currently, researchers have intensified their search for low-cost adsorbents like activated carbon produced from nonfossil sources. This study is focused on the use of Ethylene Di-Amine Tetra-Acetic Acid for the adsorption of Lead ions. It was conducted to optimize the process variables in the production of Palm Kernel Shell Activated Carbon modified with Ethylene Di-Amine Tetra-Acetic Acid. A 23 three-level Central Composite Design was used to develop a statistical model for the optimization of the time (10-130) X1, pH (5.0 – 7.0) X2, and adsorbent dose (0.4 -5.0g)X3. Data obtained from RSM on activated carbon production were subjected to ANOVA and analyzed using a second-order polynomial equation. The extent of lead ion removal by Ethylene Di-Amine Tetra-Acetic Acid activated carbon from aqueous solution was 96.30% at the solution pH of 7.2, contact time of 70 minutes, and an adsorbent dose of 2.1g/L. The Langmuir isotherm model was in good agreement with the experimental data.
