The effects of supersaturation level, sodium chloride (NaCl) as impurity, and the suspension density of the crystallizer content on the crystallization kinetics of ammonium perchlorate (AP) were studied in a mixed-suspension mixed-product removal crystallizer. The product crystals have a plate-like morphology. The crystal size distribution is not affected by the supersaturation level. There was a deviation from the ideal population density where the growth rate of pure AP crystallization was size dependent with the order of 0.4 according to Abegg, Stevens and Larson (ASL) model, However, the ASL model was not found to be suitable to express the growth rate of the crystals in NaCl containing AP solution. Also when suspension density of the crystallizer increased, secondary nucleation was observed.

Gas phase reaction kinetics in boron fibre production Firat, Fatih; Sezgi, Naime Aslı; Ozbelge, Hilmi O.; Doğu, Timur (2012-05-01) In the production of boron fibres using the chemical vapor deposition (CVD) technique, boron deposition and dichloroborane formation reactions occurs simultaneously. Boron deposition reaction occurs at the surface, whereas the formation of dichloroborane is the result of both gas phase and surface reactions. A continuous stirred tank reactor (CSTR) type of reactor was designed to investigate the reaction kinetics and kinetic parameters in the gas phase reactions of boron trichloride and hydrogen. It was con...
Water soluble polymer stabilized iron(0) nanoclusters: A cost-effective and magnetically recoverable catalyst in hydrogen generation from the hydrolysis of sodium borohydride and ammonia borane Dinç, Melek; Metin, Önder; Özkar, Saim (Elsevier BV, 2012-3) Water soluble polymer stabilized iron(0) nanoclusters were prepared from the reduction of iron(III) chloride by sodium borohydride (SB) and ammonia borane (AB) mixture in the presence of polyethylene glycol (PEG) as stabilizer and ethylene glycol as solvent at 80 degrees C under nitrogen atmosphere. PEG stabilized iron(0) nanoclusters were isolated from the reaction solution by centrifugation and characterized by UV-Vis, TEM, HRTEM, XRD, ICP-OES and FT-IR methods. The particle size of PEG stabilized iron(0)...
MOLTEN SALT ELECTROLYSIS OF MgCl2 IN A CELL WITH RAPID CHLORINE REMOVAL FEATURE Demirci, Gokhan; Karakaya, İshak (2012-03-15) An experimental electrolytic magnesium production cell was designed to remove chlorine gas from the electrolyte rapidly and demonstrate the beneficial effects of reduced chlorine dissolution into the molten salt electrolyte. The back reaction that is the main cause of current losses in electrolytic magnesium production was reduced as a result of effective separation of electrode products and decreased contact time of chlorine gas with the electrolyte. Moreover, smaller inter electrode distances employed and...
CVD of boron and dichloroborane formation in a hot-wire fiber growth reactor Sezgi, Naime Aslı; Dogu, T; Ozbelge, HO (2001-11-01) Chemical vapor deposition (CVD) of boron by hydrogen reduction of BCl, on a hot tungsten substrate was investigated in a parallel flow reactor. Effect of substrate temperature (1100-1250 degreesC) on the relative rates of formation of BHCl2 and boron was observed by the on-line analysis of the reactor effluent stream composition using an FT-IR spectrophotometer. It was concluded that BHCl2 was majorly formed in the gas phase within the thermal boundary layer adjacent to the substrate with possible contribut...
Production of lactic acid esters catalyzed by heteropoly acid supported over ion-exchange resins AYTURK, E; Hamamcı, Haluk; Karakaş, Gürkan (2003-01-01) The heterogeneous liquid-phase esterification reaction of lactic acid with ethyl alcohol accompanied with lactoyllactic acid hydrolysis over heteropoly acid supported on ion exchange resin catalysts was investigated at 343 K with ethanol to lactic acid molar ratio of 1:1. The catalysts with 5-20% of tungstophosphoric (H(3)PW(12)O(40).xH(2)O) and molybdophosphoric (H(3)PMo(12)O(40).xH(2)O) acid type of heteropoly acids over Lewatit(R) S100 showed higher activities than the resin itself. DRIFTS and XRD analys...
