Combustion kinetics of Western Kentucky No. 9 coal

The combustion kinetics of Western Kentucky No. 9 coal were measured in a tubular-flow reactor. The primary objective was to develop a kinetic eion suitable for calculating the combustion rate of devolatilized char in an atmospheric fluidized bed combustor. Coal particles ranging from about 0 Disposal of Wastes from Water Treatment PlantsThe quantity of solids resulting from municipal water coagulation processes is estimated by Hudson (1968) to total about 1,000,000 tons per year. These wastes are highly variable in composition, containing the con- centrated materials removed from raw water and the chemicals added in the treatment process.

Effects of Different Operating Temperatures on the Tensile

Jan 01, 2017 · The coefficient of thermal expansion of austenitic steel is 1.9 x [10.sup.-5]/K and that of the Colmonoy is 1.33 x [10.sup.-5]/K. Therefore, the expansion of steel is faster than that of Colmonoy during heating, and, hence, it is subjected to compressive force induced by Colmonoy. Moreover, Colmonoy, which expands slower than steel, is Identification and Characterization of the V(D)J Extracts were centrifuged at 14,000 rpm for 1 h at 4°C. The supernatant was then dialyzed for 4 h in dialysis buffer (30 mM HEPES/KOH, pH 7.9, 50 mM KCl, 2 mM EDTA, 5 mM MgCl 2, 1 mM DTT, 10% glycerol, 1 mM PMSF, and 1 . 2.9. Western Blotting.

  • AbstractIntroductionExperimental ProceduresResults and DiscussionConclusionAcknowledgmentsSophorolipids (SLs) are glycolipidic biosurfactants suitable for various biological and physicochemical applications. The nonedible Jatropha oil has been checked as the alternative raw material for SL synthesis using C. bombicola(ATCC22214). This is useful towards lowering the SL production cost. Through optimization of fermentation parameters and use of resting cell method, the yield 15.25g/L could be achieved for Jatropha oil derived SL (SLJO) with 1% v/v oil feeding. The synthesized SL displayed gSTRUCTURE OF PYROLYZED POLYVINYLIDENE CHLORIDEVapor pressures at 77.3°±0.5°K corrected for the thermomolecular pressure effect have been measured for krypton and xenon:Krypton 1.754±0.002 mm ; Xenon 1.93 ±0.01×10<sup>-3</sup> mm .

    US Patent for Continuous autodeposition method with bath

    In the coating of steel surfaces, iron is a major contaminant, with typical iron losses to the processing bath of 20-40 mg Fe/ft.sup.2 (about 200-400 mg Fe/m.sup.2) of surface treated. In large-scale commercial applications, such losses can translate into an iron build-up in the coating bath of 100 or more grams per hour, to concentrations in US Patent for Substrates adhered via ionomer resins Patent Laminates of metal-containing copolymers between various kinds of substrates can be prepared with good results, where the copolymers consist of the following monomeric units:##STR1## WHEREIN M is metal; R is a lower alkyl; R' and R" show, individually, hydrogen atom, a lower alkyl having 1 - 5 carbon atoms; and a, b, c and d are the respective mol numbers of the above-mentioned four units and US4102945A - Filled cyanoacrylate adhesive compositions US4102945A US05/814,582 US81458277A US4102945A US 4102945 A US4102945 A US 4102945A US 81458277 A US81458277 A US 81458277A US 4102945 A US4102945 A US 4102945A Authority US United States Prior art keywords cyanoacrylate composition adhesive peel strength butadiene Prior art date 1976-07-14 Legal status (The legal status is an assumption and is not a legal conclusion.
