“…The ultimate analysis of POS indicated a carbon, hydrogen and nitrogen content of 47.26, 6.18 and 0.94%, respectively ( Table 1). These values are similar to those previously determined (Nasri et al, 2014). The low nitrogen content from the analysis indicates that POS is environmental friendly.…”

“…The high volatile matter (87.78%) and moderate amount of fixed carbon (10.39%) is a typical property of agricultural residues. The results from the proximate analysis are within the range of literature review (Nasri et al, 2014). The high volatile contents make it more reactive and therefore aid during the carbonization process in creating more pores on the carbonaceous material.…”

“…Activation enlarges the pores created during carbonization together with formation of new pore structures. Activation is achieved via physical or chemical means: Physical activation involves oxidation of char using steam, air, oxygen or carbon dioxide at high temperature (800-1100°C), chemical activation involves impregnation of chemicals (such as ZnCl 2 , NaOH, HNO 3 , KI, Na 2 CO 3 , K 2 CO 3 ) and then pyrolysis at 500-800°C (Nasri et al, 2014).…”

Biogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH 4 , 20-45% CO 2 with trace amount of H 2 S and other impurities. Common H 2 S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated carbon or impregnated activated carbon. Conventionally, activated carbon is produced from biomass residues and agricultural residues such as palm oil shell which promising approach for the production of cheap. It is so due to the palm oil shell carries a large amount of carbon content which it is the main composition of activated carbon. Therefore, it is usable as raw material for producing impregnated activated carbon and used as adsorbents. The aim of this study is a produce the activated carbon from palm oil shells by chemical activation using ZnCl 2 and optimal conditions after impregnated them with NaOH, KI and K 2 CO 3 for H 2 S absorption from biogas product. In this research, production of activated carbon involved three stages; (i) carbonization of raw material in an inert atmosphere which was carbonized in a muffle furnace at 600°C for 1 h; (ii) secondly activation of char product from the first stages at fixed bed reactor (stainless steel with 54.1 mm internal diameter and 320 mm length) which was studied to observe the effect of char product: Chemical agent ratio (ZnCl 2 , 1:1 to 1:3), which there are activated at 700°C activation temperature for 2 h; and (iii) finally alkali impregnated activated carbon which were immersed 1:3 ratio in 500 mL of 1 N NaOH, KI and K 2 CO 3 solutions and stirred for 30 min. The result showed that the surface area and the pore volume increased progressively with increasing the char product: Chemical agent ratio. The maximum surface area total pore volume of activated carbon product was 532.31 m 2 /g and 0.2973 cc g −1 was obtained on ACZn13. While, the maximum surface area and the pore volume of modified impregnated activated carbon was 741.71 m 2 /g and 0.4210 cc g −1 was obtained on K 2 CO 3 -AC. The results of the experiment demonstrated that with regard to adsorption of H 2 S on K 2 CO 3 -AC which it had more than on KI-AC and NaOH was 3.26 and 8.8%, respectively. The conclusion showed that surface area, total pore volume and micropore volume were increasing with increased the char product: Chemical agent ratio (1:1 to 1:3). ACZn13 has good chemical and physical AJESproperties such as chemical content and surface area, which showed that the highest surface area (532.21 m 2 /g) and total pore volume (0.2973 cc g −1 ). Therefore, K 2 CO 3 -AC impregnated activated carbon has a high surface area and showed be an efficient adsorbent for removal of H 2 S from biogas product. Moreover, evaluating the content of H 2 S adsorption was suggested.

Solid sorbents are considered to be promising materials for carbon dioxide capture. In recent years, many studies have focused on the use of solid waste as carbon dioxide sorbents. The use of waste resources as carbon dioxide sorbents not only leads to the development of relatively low‐cost materials, but also eliminates waste simultaneously. Different types of waste materials from biomass, industrial waste, household waste, and so forth were used as carbon dioxide sorbents with sufficient carbon dioxide capture capacities. Herein, progress on the development of carbon dioxide sorbents produced from waste materials is reviewed and covers key factors, such as the type of waste, preparation method, further modification method, carbon dioxide sorption performance, and kinetics studies. In addition, a new research direction for further study is proposed. It is hoped that this critical review will not merely sum up the major research directions in this field, but also provide significant suggestions for future work.

“…This method leads to the production of numerous acidic surface groups and an interesting porosity of up to 1600 m 2 g -1 [22][23][24]. Modification via chemical oxidation/reduction is an effective way of developing the special functions of AC, reduce its usage cost, enlarge the application range, and improve the utilization efficiency [25,26]. The oxidation of AC introduces CO 2 surface groups, increases the content of O 2 -containing acidic groups (such as carboxylic, phenolic, hydroxyl, and ester groups) on the surface of the AC, and enhance the surface polarity/hydrophilicity of AC [27].…”

This paper provides a concise review of recent advances in activated carbon (AC) and its corresponding modified material. Topics covered in this work include the synthesis and characterization of AC as the feedstock materials, as well as the properties and applications of the subsequent hybrid material for different industries. Numerous research studies have since reported remarkable physical, chemical, thermal, conductivity, porosity, and mechanical (stiffness and strength) properties of AC in different types of multiple material matrices, including polymers, metals, and ceramics. The incorporation of AC particles into material matrices may result in the formation of an entire new class of advanced materials, due to the resulting strong interfacial bonds of the hybrid components. Although this requirement is no different from those that offer conventional hybrid materials, the scale of the reinforcement and filled phase of the AC has changed from micrometers to nanometers. This create opportunities to increase the potential applications of AC hybrid materials of the development of fundamentally unique new materials for in chemical conversion, environmental, and fuel storage applications.
