Book Description
The objectives of this experiment were to prepare the activated carbon from matured palm kernel shell as a raw material by carbonization and the studied which optimum variables such as temperature, concentration of phosphoric acid and cooling down time are suitable. Activated carbon is a form of carbon that has been processed to make extremely porous and have very large surface area for adsorption and chemical reactions. The matured palm kernel shell is carbonized in a glass furnace at elevation temperature after soaked with H3PO4 acid and cooled down the carbonized activated carbon. Methyl orange are used as an indicator to test the carbonized raw material whether it is activated carbon or common charcoal. The real activated carbon would change the orange solution to a clear solution and the solution of different color is analyzed by using FTIR to check the functional group of methyl orange. The result showed that 1000oC is the optimum temperature to carbonize the raw material and the use of 0.35M 3PO acid with the cooling down time at 30 minutes would give the best adsorption of activated carbon after filtration. From the data obtained by FTIR, the 0.35M H43PO acid has showed that the peak functional group of methyl orange is reduced from first filtration till last filtration. It is recommend that the raw material not to be crushed small than 0.2 mm, because it will effect the adsorption and filtration rate. As a conclusion, The activated carbon has been produced from matured palm kernel shell using glass furnace and The optimum effect of variables have been determined by observation and analysis of FTIR, it is at 100004 C of temperature, by impregnated in 0.35M of Phosphoric acid and cool the activated carbon down in 30 minutes are found to be the optimum variables in producing the activated carbon.

Book Description
Palm kernel shell was carbonised in an indirect pyrolysis reactor at 759 C, and the charcoal crushed, ground and sieved. The granulated shell charcoal was activated at 800 C in an atmosphere of superheated steam. Good palm kernel shell activated carbon with an average CTC and I2 values of 50% and 900 respectively was obtained. Based on a typical production capacity of 1,250 tonnes/ year and current market prices of raw material, labour, factory overheads, the net return of the plant was estimated to be 34.6% to 37.8%.

Book Description
Highly Efficient Activated Carbon (HEAC) as an adsorbent of toxins has been successfully produced from palm shell through chemical activation process using phosphoric acid as an activating agent. Palm Kernel shell used as the main raw material for activated carbon production, was purchased from a local oil palm mill in Pahang, Malaysia. Temperature range 550 oC - 650 oC was used during the activation process. The effect of temperature variation on the pore size and surface morphology of the activated carbon were studied. Well developed pore size and low number of functional groups observed on activated carbon at 600 oC were determined by Scanning Electron Microscope (SEM) and Fourier- Transform Infrared (FTIR) spectroscopy, respectively. The surface area and pore volume were determined by Brunauer, Emmett and Teller (BET) method using N2 gas adsorption. The highest surface area (1287 m2g-1) and pore volume (0.74 cm3 g-1) was observed with sample HEAC-2. The adsorption efficiency of HEAC-2 was studied in vitro for paraquat as toxin using distilled water and NaCl (0.9%) solution. These study shows paraquat was adsorbed more on HEAC-2 in the presence of sodium chloride solution (4.68 mgL-1) than in distilled water (3.62 mgL-1). Furthermore, a comparision was done between HEAC-2 (4.68 mgL-1) and commercially available activated carbon (4.18mg L-1) which proved HEAC-2 is more effective than commercially available activated carbon.

Book Description
The present book discusses the principal lignocellulosic precursors used in the elaboration of activated carbons in different countries such as Asia, America, Europe and Africa; the different methods and experimental conditions employed in the synthesis of activated carbons, including one analysis of the principal stages of the preparation such as carbonization and activation (i.e., chemical or physical activation). Also, the recent and more specialized techniques used in the characterization of activated carbons are discussed in this book. For example, the techniques employed to determine textural parameters (mercury porosimetry and gas adsorption isotherms at 77 K) and different spectroscopies to determine chemical functionality (Raman, FT-IR, etc.) and other X-Ray techniques. Additionally, an overview of the application of activated carbons obtained from lignocellulosic precursors for wastewater treatment. Specifically, the analysis and discussion are focused on the advantages and capabilities of activated carbons for the removal of relevant toxic compounds and pollutants from water such as heavy metals, dyes, phenol, etc. Finally, the use of pyrolysis method for the valorization of two Mexican typical agricultural wastes (orange peel and pecan nut shell) for energy and carbon production is considered in this book.

Book Description
The production of alternative activated carbon has been resolved to replace the costly activated carbon to remove unwanted heavy metals from contaminated water at low cost. Heavy metals are very toxicity and can harm human body. The environmental pollution became increase due to the discharge of wastewater including heavy metals and toxic nature of copper affects water resources. In this study, activated carbon produced locally from palm kernel shell was examined for the copper removal from aqueous solution by using adsorption process. Palm kernel shell not just available to get but inexpensive material that have ash content, fixed carbon, high carbon and low inorganic content. Adsorption studies conducted in completely to shown the ability of the produced activated carbon to remove copper from aqueous solutions in certain range of pH. The investigation was carried out by studying the influence of pH (1-5), adsorbent dosage (0.3-1.5 g) and initial concentration (150-350 mg/L). The result of the study shown that activated carbon from palm kernel shell with large surface area has high percentage capacity of copper removal compared to small surface area. From the result showed that the optimum parameters for maximum removal efficiency were follows as adsorbent dose (1.5 g), pH (5) and initial concentration (150 mg/L). Based on the batch adsorption experiment, the adsorption isotherm studies indicated that Langmuir model fits better for the present case. While adsorption kinetic indicated that pseudo second order model is the best for the present case.
