Effect of template constraints on adsorption properties of synthetic carbons prepared within the gallery of layered double hydroxides

Effect of template constraints on adsorption properties of synthetic carbons prepared within the gallery of layered double hydroxides. Putyera, K.; Bandosz, T. J.; Jagieo, J.; Schwarz, J. A. (Dep. Chem. Eng. Materials Science, Syracuse Univ., Syracuse, NY 13244-1190, USA). Carbon, 34(12), 1559-1567 (English) 1996 Elsevier. CODEN: CRBNAH. ISSN: 0008-6223. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 66 Mg-Al layered double hydroxides were synthesized and 1,5-naphthalene disulfonate dianions were intercalated; the org. mols. were carbonized within the layered framework. For comparison, a ref. carbon was prepd. from the sodium salt of the 1,5-naphthalene disulfonic acid precursor using conventional carbonization under the same thermal and post-treatment conditions. The surface properties of the carbonized product extd. 11138-49-1 and 7760-50-1 are also in the experiment. from the carbon-mixed oxide nanocomposite were studied by adsorption techniques and the results compared to the adsorption characteristics of the ref. carbon. The sorption of nitrogen at 77 K and carbon dioxide at 298 K demonstrate that, although the two carbons have almost the same sp. surface area and total pore vols., there is a significant difference in their micropore structure. Micropore size distributions calcd. from adsorption isotherms of methane and sulfur hexafluoride at near ambient temps. reveal a more heterogeneous micropore structure of the template derived carbon compared to the ref. The factors controlling micropore structure development during two-dimensional carbonization are discussed based on DTA, results of sorption of carbon dioxide and FTIR spectroscopic measurements. .

Comparative analysis of conditions for producing active magnesium oxide in industrial reactors and selection of basic parameters

Comparative analysis of conditions for producing active magnesium oxide in industrial reactors and selection of basic parameters. Shaporev, V. P.; Bulat, A. E.; Dolkart, A. F.; Vorob'eva, R. D. (Gos. Nauchno-Issled. Pproektn. Inst. Osn. Khim., Kharkov, USSR). Deposited Doc., SPSTL 255 Khp-D82, 15 pp. Avail. SPSTL (Russian) 1982. DOCUMENT TYPE: Report CA Section: 49 (Industrial Inorganic Chemicals) The kinetics of thermal decompn. was studied of MgCO3.3H2O and 4MgCO3.Mg(OH)2.4H2O having particle size 150-220 m in a pilot-scale muffle furnace (2 ′ 1 ′ 0.65 m). During the expt. the temp. of the furnace gases, reaction chamber wall, roasting material, etc. was detd. 7760-50-1 and 546-93-0 which are cas registry numbers of substances are two of reagents here. The decompn. process is characterized by simultaneous reaction on the surface and heat and mass transfer through the solid phase. Equations are given for calcg. the optimal temp. and period of roasting for obtaining MgO of given properties for various types of furnaces. The application of the equation to roasting is illustrated by using Mg(OH)2 roasting in a cyclone furnace as an example. .
