Book Description
The research objective was to produce activated carbon from palm-oil shells by one step pyrolysis and steam activation in a fixed bed reactor with the diameter of 100 mm. The studied variables were temperatures, times, palm-oil shells sizes and flow rates of air. The results showed that the optimum condition was 1.18-2.36 mm of palm-oil shells at 750 C for 2 hr with air flow rate of 0.72 nl/min, using steam as an activating agent. The characteristics of the resulted activated carbon with the yield of 19.66% were bulk density of 0.5160 g/cm3, 6.03% ash, iodine number of 620.16 mg/g, methylene blue number of 176.75 mg/g and 559.48 m2/g B.E.T. surface area. In addition, it had been found that when there was an adding of pyrolysis time with air before steam activation led to higher porosity development than one step pyrolysis and steam activation. From these experimental data, it was observed that the maximum surface area and adsorption capacity could be obtained from using 200 g of 1.18-2.36 mm of palm-oil shells at 750 C for 3 hr by adding pyrolysis with air for 30 min (0.72 nl/min) before steam activation. The resulting characteristics of the final product with the yield of 12.18% were bulk density of 0.5048 g/cm3, 7.54% ash, iodine number of 766.99 mg/g, methylene blue number of 189.20 mg/g and 669.75 m2/g B.E.T. surface area.

Book Description
This research was the study of the production of activated carbon from used tires by the processes of carbonization and activation with superheated steam and carbon dioxide in a fixed bed reactor with the diameter of 100 mm. The used tires were carbonized at 350 C for 60 min with the air flow rate of 0.52 nl/min. The characteristics of the resulted chars were yield of 41.40%, fixed carbon of 62.57%, ash of 15.30% and volatile matter of 22.13%. Then, the chars were activated with superheated steam and carbon dioxide. The optimum condition for activation was 0.60-1.18 mm of the chars size at 900 C for 45 min with air at a flow rate of 0.27 nl/min, carbon dioxide at a flow rate of 2.0 nl/min and superheated steam. The resulted activated carbon obtained yield of 27.99%, bulk density of 0.3590 g/cm3, ash of 21.05%, iodine number of 598.79 mg/g, methylene blue number of 247.08 mg/g, B.E.T. surface area of 658.75 m2/g, micropore area of 424.27 m2/g, external area of 234.48 m2/g and average pore diameter of 22.24 A.

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.
