Carbon molecular sieves from bituminous coal by controlled coke deposition

Microwave heating as a novel method for introducing molecular sieve properties into activated carbon fibres

“…The best result in Table 2 was obtained with F1N-0 and is comparable to the results reported by Vyas et al [15]. However, it is clear that a more detailed study is still necessary in order to achieve a higher CO 2 uptake.…”

“…For CO 2 /CH 4 separation various authors have reported selectivities greater than 40 with CO 2 uptakes as high as 45 cm 3 g À1 [6,8,9,11,12,[14][15][16]. The best result in Table 2 was obtained with F1N-0 and is comparable to the results reported by Vyas et al [15].…”

Synthesis of carbon molecular sieves by benzene pyrolysis over microporous carbon materials

“…CMS have a lot of advantages given to the zeolite molecular sieves [5,6], like its high hydrophobicity, its resistance as in alkaline as in acid medium, and its structural stability at high temperatures. A review of different research teams involved in CMS synthesis was reported by Juntgen [7].…”

“…In varied trials, it was studied the effect of coke deposition through the cracking of hydrocarbon in activated CMS samples [6]. The average diameter of the pores can be adjusted by the intensive treatment on the cracking process.…”

Carbon Dioxide Adsorption Using Activated Carbon via Chemical Vapor Deposition Process

“…Commercial granular activated carbon (GAC) purchased from METRA Co. Ltd. of 10 g was deposited with acetylene by chemical vapor deposition process under 5, 10, 15, and 20 ml/min of acetylene and 50 ml/min of nitrogen flow for 15, 30, 45, and 60 min at 600, 700, 800, and 900 °C [5]. Afterwards, carbon molecular sieve produced from GAC (CMSGAC) was analyzed for BET specific surface area and iodine number in order to find out the optimum condition as shown in Table 1.…”
