Book Description
The preparation of activated carbon from palm oil shells was caried out in two consecutive steps: carbonization of the raw material at 450 C to the intermediate char which was converted to the activated carbon product via steam gasification at 850 C. For every different variable under study the yield and the specific surface area of the product were determined. The optimum duration of activation was 45 minutes which gave a specific surface area of 710m2/g and a yield of 21%. [Authors' abstract].

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 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.
