“…The specific surface area (S BET ) of feroxyhyte is 203 m 2 /g which is virtually equal to 200 m 2 /g reported by Schwertmann & Cornell for the oxyhydroxide obtained using this method [18] . This value can also be considered average compared to feroxyhytes synthesized using other methods [31–33] . Other porous texturel parameters were as follows: total porosity (V tot ) – 0.601 cm 3 /g, volume of micropores (V mic ) – 0.075 cm 3 /g and volume of mesopores (V mes ) – 0.316 cm 3 /g.…”

Feroxyhyte (δ‐FeOOH) was synthesized and characterized using X‐ray diffractometry (XRD), simultaneous thermal analysis (STA), scanning electron microscopy coupled with energy dispersive X‐ray spectroscopy (SEM‐EDS), and low‐temperature nitrogen adsorption‐desorption measurements. Its potential application as adsorbent of an anionic and cationic dyes such as C.I. Acid Violet 1 (AV1) and C.I. Basic Blue 3 (BB3) was investigated by determining the adsorption capacities based on the Langmuir (36.6 mg/g for AV1 and 187 mg/g for BB3), Freundlich and Dubinin‐Radushkevich isotherm models. Adsorption of AV1 and BB3 by δ‐FeOOH drops with the presence of additives such as cationic and anionic surfactants (SDS, CTAB) and ionic polymers (PAA, PEI). The surface and electrokinetic properties of examined suspensions were also described. They include determination of the solid surface charge density and the zeta potential, as well as values of point of zero charge and isoelectric point of feroxyhyte particles without and with adsorbed layers of organic substances. Their analysis made possible to propose the most probable structure of electrical double layer formed at the iron mineral/aqueous solution interface.

“…For studies on the air/coal ratio and steam/coal ratio effect on reaction temperature earlier researchers used the da Xuzhou bituminous type coal in a CFB system and clarified that the increase in air/coal ratio increases the gasifier temperature but in case of steam/coal, bed temperature continuously decreases. The ratio also affects the CO and H2 concentration in the output gas [65][66].…”

In this paper a brief review on hydrodynamic characteristic of coal gasification is presented. Firstly an introduction of hydrodynamics then parameters related to hydrodynamics is discussed. In the last several decades Coal gasification is an important method to use of coal resources. The hydrodynamic characteristics have an important role to design of Circulating fluidized bed gasifiers. Circulating fluidized bed (CFB) gasifiers widely use due to their high reaction rates and high thermal efficiency. The present study includes some hydrodynamics properties of coal gasification such as effect of pressure and temperature, solid hold up, solid circulation rate, gas-solid contact, particle residency time, coal feeding rate and coal feeding position. During the brief review on hydrodynamics characteristics of coal each section of CFBs such as riser, cyclone, stand-pipe and loop seal have been considered.
