Preparation of activated carbon from petroleum coke by KOH chemical activation for adsorption heat pump

Preparation and characterization of activated carbon from a new raw lignocellulosic material: Flamboyant (Delonix regia) pods

“…Researchers have reported the preparation of chemically activated carbons from many kinds of raw materials, as for example from coconut husk (Hameed et al, 2008), Spanish anthracite (Lozano-Castelló et al, 2007), olive husk (Michailof et al, 2008), sewage sludge (Lillo-Ródenas et al, 2008), petroleum coke (Kawano et al, 2008), Siberian anthracite (Nowicki et al, 2008), coffee endocarp (Nabais et al, 2008), cotton stalks (El-Hendawy et al, 2008), plum kernels (Tseng, 2007), coal tar pitch (Maciá-Agulló et al, 2004), fir wood and pistachio shells (Wu et al, 2005), and olive stones (Ubago-Pérez et al, 2006). In this work, a new raw material, flamboyant pods (Delonix regia), was used.…”

NaOH-activated carbon from flamboyant (Delonix regia) pods: Optimization of preparation conditions using central composite rotatable design

“…Researchers have reported the preparation of chemically ACs from many kinds of raw materials, such as coconut husks [6,7], Spanish anthracite [3], olive husk [8], sewage sludge [9], petroleum coke [10], Siberian anthracite [2], coffee endocarp [11], cotton stalks [12], plum kernels [13], coal tar pitch [4], fir wood and pistachio shells [14,15], and olive stones [16]. Besides being renewable resources, biomasses are inexpensive, largely available, have low ash contents, a greater diversity, and a short production time.…”

Preparation of mesoporous carbons from amphiphilic carbonaceous material for high-performance electric double-layer capacitors

“…Coal, petroleum coke (PC), and needle coke (NC), with high carbon content, economic cost, low volatile and ash content, are conventional carbonaceous precursors. As far as we know, ACs with surface area beyond 2000 m 2 g −1 have been prepared from these materials via chemical activation, and such kinds of ACs generally have fairly high capacitance [6][7][8][9][10][11]. However, there are some limitations for developing ACs with ideal EDLC performances from traditional precursors.…”
