This book was released on 1999 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research was the study of deposition of zine in the process of preparation of activated carbon from anthracite and palm-oil shell by zine chloride activation in a fixed bed reactor. The palm-oil shell was cabonized at 400 °C for 1 hr. Then, the chars and anthracite were soaked in zinc chloride solution before activation. The studied variables were temperature, time, palm-oil shell char particle size and concentration of zine chloride. The optimum condition for activation was 1.18-2.36 mm of palm-oil shell char and anthracite for the particle size of 0.80-0.90 mm, at 800°C for 3hr, 40% concentration of zine chloride. The prepared activated carbon from anthracite gave yield of 30.13%, bulk density of 0.5879 g/cm3 , iodine number of 860.35 mg/g, methylene blue number of 583.03 mg/g, B.E.T. surface area of 1026.99 m2 /g and 0.20% deposition of zinc. For the prepared activated carbon from palm-oil shell obtained yield of 33.83%, bulk density of 0.5063 g/cm3 , iodine number of 1069.10 mg/g, methylene blue number of 600.25 mg/g, B.E.T. surface area of 1099.10 m2 /g and 0.20% deposition of zinc. This activated carbon prepared from two types of raw material, could be used in commercial (iodine adsorption at least 600 mg/g) and food grade industry, because it has very low concentration of zine in product which is acceptable.

This book was released on 2006 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of batch laboratory studies were conducted in order to investigate the suitability of palm kernel shell (PKS)-based activated carbon for the removal of cadmium (cadmium ions) and zinc (zinc ions) from their aqueous solutions. Single and binary adsorption isotherms and kinetics were investigated. All batch experiments were carried out at a constant temperature of 30±1oC using an incubator shaker that operated at 150 rpm. A concentration ratio of cadmium and zinc used in the adsorption of binary system is 1:1. Batch equilibrium studies showed that adsorption of cadmium and zinc were highly pH dependent. Uptake of cadmium and zinc increased with pH with maximum removal observed at pH 7.0, and decreased thereafter with further increase in the initial pH. In a single component system, the adsorption capacity of cadmium was higher than zinc, whilst in a binary component system, the adsorption capacity of zinc was higher than cadmium. The single component equilibrium data was analyzed using the Langmuir, Freundlich and Redlich-Peterson isotherms. Overall, the Redlich-Peterson isotherm showed the best fit for all adsorption under investigation in terms of correlation coefficient as well as error analysis. For all the systems studied, the analysis of isotherm shape factor showed that the adsorption was favorable. Equilibrium isotherms for the binary adsorption of cadmium (II) and zinc (II) ions onto PKS-base activated carbon have been analyzed by using the ideal adsorbed solution (IAS) theory, extended Langmuir (EL), modified extended Langmuir (MEL), modified extended Freundlich (MEF) and modified extended Redlich-Peterson (MERP) models. The binary isotherm data could be described reasonably well by the modified extended Langmuir model. The kinetics of single and binary systems describing the sorption of cadmium and zinc have been investigated. The rate models evaluated include the pseudo first order, the pseudo-second order and the intraparticle diffusion models. Kinetic data showed that the adsorption rates were a function of initial adsorbate concentration. For both single and binary systems, the pseudo-second order model correlate excellently the experimental data, suggesting that chemisorption processes could be the rate-limiting step.

This book was released on 1998 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2016 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
