“…There is a need to explore the use of FPW for more organic or inorganic pollutants. FPW should also be studied for adsorption of gaseous pollutants such as ammonia, methane, CO 2 , and NO X (Giraldo et al 2014). Apart from listed pollutants, other contaminants should be explored for adsorption on FPW.…”

AbstractFruit peel waste (FPW) is abundantly available from the agricultural and food processing industry and has been studied in recent past as an adsorbent. This paper critically reviews the reported work and investigates various FPW-pollutant systems. The study includes statistics of FPW generation, modification, characterization, adsorption ability, recovery/regeneration, and modeling (isotherms, kinetics, and thermodynamics) of batch adsorption. It is found that orange and banana peels are the most extensively studied adsorbents, whereas Pb

“…Acid gases such as sulfur (IV) oxides SO 2 and nitrogen oxides compound (NO x ) are mostly emitted as a result of fossil fuel combustion in power plants and many other anthropogenic sources causing harm to humans, environment and the ecosystem at large [1]. Therefore, gas cleaning and proper utilization of such harmful gases has continued to be a topic of research and various adsorbents such as activated carbon, zeolites, metal-organic frameworks, amines, and monolith are investigated [2]. Because monolith adsorbent is composed of high surface area, it is used in heterogeneous catalysis as a catalyst or active support component, it is also used as three-way catalysts (TWCs) in automotive exhaust gas purification, electrochemical reactors, electric swing adsorption (ESA) [3], gas-solid, and gas-liquid-solid applications [4].…”

The application of monolith in adsorption process is still limited but gaining attention by the day [2,5]. The interaction between a catalyst precursor (example, metal oxide) and the support (example, monolith) is very critical in the gas cleaning operation, metal oxide such as CuO are impregnated on adsorbents to fasten the reaction between the adsorbates and the adsorbent.…”

The aggressive acid treatment creates a wealth of oxygen-containing functional groups (-OH, C=O, C-O) on the surface of an adsorbent and acts as binding sites for catalyst support therefore, in this study, the surface of monolith (ACM) was oxidized via the acid modification and high temperature activation. Various types of catalysts from the precursors of cerium nitrate (CeO2 /ACM), copper nitrate (CuO/ACM) and cobalt nitrate (Co3 O4 /ACM) using the deposition precipitation synthesis method. The catalyst activity tests were investigated in a fixed bed reactor by passing a stream of flue gas generated by burning coal. The breakthrough study of SO2 /NOx and the experimental results showed that for CeO2 /ACM catalyst the adsorption capacity of SO2 was 24.3 and 18.5 mg/g for NOx and for CuO/ACM catalyst they were 27.0 and 32.8mg/g and for Co3 O4 /ACM catalyst, values obtained were 10.6 and 49.7mg/g. FTIR, BET and FESEM analysis were performed. This investigation depicts the development of highly efficient adsorbent for flue gas treatment.

“…Other option is to directly obtain ACM by the extrusion of a carbonaceous paste. In this sense, only a few works reported the preparation of ACMs with a honeycomb structure by this method [20,21]. To our best knowledge, the preparation of ACM with well-defined axial channels by extrusion of lignin was firstly reported by our research group [22].…”

Activated carbon monoliths (ACMs), with 25 cells/cm2, were prepared from the direct extrusion of Alcell, Kraft lignin and olives stones particles that were impregnated with phosphoric acid, followed by activation at 700 °C. These ACMs were used as catalysts for methanol dehydration reaction under air atmosphere. ACM that was prepared from olive stone and at impregnation ratio of 2, OS2, showed the highest catalytic activity, with a methanol conversion of 75%, a selectivity to dimethyl ether (DME) higher than 90%, and a great stability under the operating conditions studied. The results suggest that the monolithic conformation, with a density channel of 25 cells/cm2 avoid the blockage of active sites by coke deposition to a large extent. Methanol conversion for OS2 was reduced to 29% in the presence of 8%v water, at 350 °C, although the selectivity to DME remained higher than 86%. A kinetic model of methanol dehydration in the presence of air was developed, while taking into account the competitive adsorption of water. A Langmuir-Hinshelwood mechanism, whose rate-limiting step was the surface reaction between two adsorbed methanol molecules, represented the experimental data under the conditions studied very well. An activation energy value of 92 kJ/mol for methanol dehydration reaction and adsorption enthalpies for methanol and water of −12 and −35 kJ/mol, respectively, were obtained.
