The conversion of Elbistan lignite into nitrogen-rich, alkali-soluble humic acid (ammonium nitrohumate) and its use as a coal binder were investigated. The optimum conditions for nitric acid oxidation and ammoniation were determined. The optimum HNO3 concentration was determined as 4.87 wt%. As a result, a humic acid solution containing 10.75 wt% nitrogen was obtained with 88.2 wt% recovery from Elbistan lignite. Coal-derived humic acid was used as a binder in briquetting of Tuncbilek lignite fines. It was possible to produce water-resistant and durable briquettes. (C) 1997 Elsevier Science Ltd.

SYNTHESIS OF MAINLY LINEAR POLY(DICHLOROPHENYLENE OXIDE)S BY THERMAL POLYMERIZATION IN SOLUTION SANLI, O; KISAKUREK, D (1992-03-01) Thermal decomposition of bis(4-bromo-2,6-dichlorophenoxo)-(N,N,N',N'-tetramethylethylenediamine)copper(II) complex in toluene, bis(4-bromo-2,6-dichlorophenoxo)(N,N-dimethylformamide)copper(II) complex in N,N-dimethylformamide and bis(4-bromo-2,6-dichlorophenoxo)dimethyl sulfoxide)copper(II) complex in dimethyl sulfoxide was achieved at 70-degrees-C. 4-Bromo-2,6-dichlorophenol derivatives prefer 1,4-addition to 1,2-addition, leading to highly linear polymers irrespective of the substituted ligands. The compl...
DEVELOPMENT OF PB-RICH (BI, PB)3SR2CA2CU1OX PHASE DURING REFORMATION OF LEAD DOPED 2223 SUPERCONDUCTING PHASE FROM MELT QUENCHED GLASS Özkan, Necati (1992-05-01) The reformation process of the lead doped superconducting 2223 phase from the melt quenched glass was investigated. It was shown that during the crystallisation of the glass a new lead rich phase, Bi0.5Pb3Sr2Ca2CU1Ox, was formed and severe copper segregation was observed. The volume fraction of the high T(c) 2223 phase increased with annealing time for an annealing temperature of 840-degrees-C. A glass sample annealed at 840-degrees-C for 150 h showed two superconducting transitions T(c) = 107 K and T(c) = ...
Production of modified clays and their use in polypropylene-based nanocomposites Seyidoglu, Tijen; Yılmazer, Ülkü (2013-01-15) The use of modified bentonite as a reinforcement in polypropylene (PP)/organoclay/maleic anhydride grafted polypropylene (MAPP) nanocomposites was investigated. The modified bentonites (organoclays) were prepared from raw (unpurified) bentonite (RB) and two quaternary ammonium salts with long alkyl tails: hexadecyl trimethyl ammonium bromide [HDA][Br] and tetrakisdecyl ammonium bromide [TKA][Br]. The ternary composites were produced by using a corotating twin screw extruder, followed by injection molding, a...
Production of an acetone-butanol-ethanol mixture from Clostridium acetobutylicum and its conversion to high-value biofuels Sreekumar, Sanil; Baer, Zachary C.; Pazhamalai, Anbarasan; Günbaş, Emrullah Görkem; Grippo, Adam; Blanch, Harvey W.; Clark, Douglas S.; Toste, F. Dean (Springer Science and Business Media LLC, 2015-03-01) Clostridium acetobutylicum is a bacterial species that ferments sugar to a mixture of organic solvents (acetone, butanol and ethanol). This protocol delineates a methodology to combine solventogenic clostridial fermentation and chemical catalysis via extractive fermentation for the production of biofuel blendstocks. Extractive fermentation of C. acetobutylicum is operated in fed-batch mode with a concentrated feed solution (500 grams per liter glucose and 50 grams per liter yeast extract) for 60 h, producin...
Use of aluminium dross for slag treatment in secondary steelmaking to decrease amount of reducible oxides in ladle furnace Aydemir, Onur; Geveci, Ahmet; Department of Metallurgical and Materials Engineering (2007) In this study it was aimed to analyse refining processes such as decreasing reducible oxide content of ladle slag with affecting parameters in low carbon aluminum killed grades and for the research Erdemir low carbon steel grades 7112K and 7110K are selected. There was a negative correlation between reducible oxide amount in ladle slag and desulphurization capacity of ladle slag with metal-slag reaction and steel internal cleanliness. To refine these properties of slag, aluminium dross, which was aluminium ...
