The use of microwave radiation for obtaining activated carbons from sawdust and their potential application in removal of NO2 and H2S

Activated carbon from Diplotaxis Harra biomass: Optimization of preparation conditions and heavy metal removal

“…The activated carbon can be produced from various fossil carbon sources such as lignite, peat and oil residues, however the depletion of these resources encourages researchers to use renewable resources from biomass as precursors for activated carbons [14]. Moreover, a number of lignocellulosic biomasses including date palm tree [15], marine red alga Pterocladia capillacea [16], hemp (Cannabis sativa L.) [17], macadamia nut shells [18], almond shell and orange peel [19], mung bean husk [20], coconut frond [21], sawdust [22], de-oiled canola meal [23], Enteromorpha prolifra [24], and macroalgae waste [25] have been tested as precursors in the production of activated carbon.…”

Removal of NO2 by carbonaceous adsorbents obtained from residue after supercritical extraction of marigold

“…Continuous broadening of the range of their use leads to increased demands for activated carbon adsorbents, which stimulates the search for new carbon precursors. The most interesting materials (among those previously proposed in literature) are all kinds of post-agricultural waste materials (Achaw and Afrane 2008;Kazmierczak-Razna et al 2015;Martinéz et al 2006;Nowicki et al 2012). Attractive precursors of activated carbons can be also the waste products left after extraction of plant raw materials with supercritical CO 2 .…”

The effect of mineral matter on the physicochemical and sorption properties of brown coal-based activated carbons

“…From among the various materials used for this purpose (Goscianska et al 2013;Wiśniewska et al 2007Wiśniewska et al , 2013Wiśniewska et al , 2014Kierys et al 2013;Wiśniewska 2010Wiśniewska , 2012Krysztafkiewicz et al 2002;Thomas and Syres 2012;De Smedt et al 2015;Qian et al 2015) the most popular and promising are the carbonaceous sorbents, especially activated carbons (Jiang et al 2015;Deng et al 2015;Sharma and Upadhyay 2009;Goscianska and Pietrzak 2015;Jiang and Chen 2011). Such materials could be prepared in a simple way by physical or chemical activation of variety of organic substances, including wood (Wang et al 2009;Nowicki et al 2015a), peat (Khadiran et al 2015), fossil coals (Nowicki and Pietrzak 2011;Maroto-Valer et al 2005;Teng et al 1998) as well as many biodegradable (Karagöz et al 2008;Soleimani and Kaghazchi 2008;Kazmierczak et al 2013Kazmierczak et al , 2015Nowicki et al 2015b) and industrial waste (Nakagawa et al 2003;Hofman and Pietrzak 2011;Nowicki et al 2013;Lin and Teng 2002). Taking into account economic and ecological aspects, particularly suited for this purpose are fossil coals of low quality, the use of which in a chemical industry (e.g.…”
