Theoretical and experimental SO2 adsorption onto pistachio-nut-shell activated carbon for a fixed-bed column

Breakthrough adsorption studies of mixed gases on mango (Mangifera indicaL.) seed shell derived activated carbon extrudes

“…64 The feasibility of bio-carbon as adsorbent in water streams [28] 65 are well studied for the removal of colour [29,30] and hazardous 66 metal [31][32][33]. Adsorption of various gases and volatiles on 67 biomass derived activated carbon was reported [34][35][36][37][38][39][40][41], still many 68 of the biomass derived activated carbon need to be evaluated as 69 potential adsorbent in gas phase. Breakthrough adsorption of 70 mixed gases on bio-carbons is very rarely addressed, for gas 71 separation application.…”

“…37 Alternative to absorption process is physical adsorption on 38 porous solids as adsorbent. The adsorption based technology 39 demands efficient porous adsorbents with high CO 2 adsorption 40 capacity, higher selectivity for CO 2 , low heat of adsorption, low 41 cost and thermal as well as chemical stability under operating 42 conditions. Numerous porous solids have been investigated as 43 adsorbents such as zeolites [2][3][4], metal organic frameworks 44 (MOFs) [5], polycarbazoles [6], covalent organic polymers [7], 45 covalent organic frameworks [8], porous organic polymers [9,10], 46 porous polymer networks and zeolitic imidazolate frameworks 47 [11].…”

Comparative study between physicochemical characterization of biochar and metal organic frameworks (MOFs) as gas adsorbents

“…The application depends on the properties of the biochars, which in turn depend on the feedstock type, pyrolysis temperature, and residence time . Biochar can be generated through thermal treatment of lignocellulosic biomass, such as coconut, almond, hazelnut, palm kernel shells, rice husks, and wood, as well as municipal and industrial waste and activated sludge . Using biochar as an adsorbent in the gas treatment process could be a sustainable approach if the biomass source is a waste material.…”

Adsorption of Copper(II) Ions onto Hazelnut Shell and Apricot Stone Activated Carbons

“…The raw material has a very large influence on the characteristics and performance of the resulting activated carbon. There have been many studies on the production of low-cost activated carbons from agricultural wastes such as corn cob (Tsai et al 1997(Tsai et al , 2001), pomegranate seeds (Uçar et al 2009), date pits (Girgis and El-Hendawy 2002;Belhachami et al 2009), apricot stone (Gergova andEser 1996;Savova et al 2001;Shalaby et al 2006), pistachio nut shell (Lua and Yang 2009), almond shell, nut shell, peach stone (Savova et al 2001;Heschel and Klose 1995), oat hulls, corn stover (Fan et al 2004), peanut hull , apple pulp (Suárez-Garcia et al 2002), coconut shell (Mozammel et al 2002;Hu et al 2001), soybean oil cake (Tay et al 2009), hazelnut shell (Heschel andKlose 1995;Kobya 2004), grapeseed (Savova et al 2001;Gergova et al 1994), bamboo (Liu et al 2010), sour cherry stone (Savova et al 2001), pecan shells (Klasson et al 2009), olive stone (Savova et al 2001;Sabio and Rodriguez-Reinoso 2004) and rice husk (Yalcin and Sevinc 2000).…”
