Title: Preparation and characterization of In(I)-{beta}''-alumina

Abstract

In(I)-{beta}''-alumina has been prepared by ion exchange from Na-{beta}''-alumina. It is stable on heating in air up to 400 deg. C. Its structure was determined by Rietveld analysis using high-resolution X-ray powder diffraction data [R-3m, a = 5.6044(1) A, c = 34.4807(1) A, Z = 3]. The coordination of In(I) in this material is asymmetric, as indicated by the distortion index for this cation, suggesting some stereochemical activity for the lone pair on the cation. However, the distortion is not as pronounced as that seen in the Ga(I) analogue.

  • Bimetallic PdSn, PdSb, PdPb, and PdGe on alumina catalysts with a low metal content have been prepared using either chloride or organometallic precursors. For the catalysts obtained from chloride precursors no interaction was observed between the two metals, and the catalysts behaved like pure Pd/Al{sub 2}O{sub 3}. In contrast, the reactions of (C{sub 4}H{sub 9}){sub 4}Sn, (C{sub 4}H{sub 9}){sub 4}Pb, (C{sub 4}H{sub 9}){sub 4}Ge, or (C{sub 4}H{sub 9}){sub 3}Sb in n-heptane solution with reduced Pd/Al{sub 2}O{sub 3} catalyst yielded a supported alloy. The interaction between metallic palladium and the organic modifier is highly selective and leads to the formation ofmore » a well-tailored bimetallic catalyst. When these final solids are reduced at 573 or 773 K, the second metal locates preferentially at the outer layer of the bimetallic aggregates. After reduction at 773 K large metallic aggregates are obtained (particle size 15 nm), and the formation of {beta}-palladium hydride, which can be formed with pure palladium catalysts, is suppressed by the addition of a small amount of the second metal. The specific activity of the palladium surface atoms for isoprene hydrogenation is then lowered, and the selectivity increased.« less
  • Catalysts were studied for the deuterium exchange reaction between hydrogen and water, and nickel--chromia supported on ..gamma..-alumina spheres. Porous ..gamma..-alumina spheres were impregnated with solutions of nickel and chromium compounds. Electron probe microanalysis was used to measure concentration profiles and total nickel and chromium content. Scanning electron microscopy was used to examine the surface morphology, and mercury porosimetry was used to measure pore volumes. Total surface areas were measured by nitrogen adsorption. Nickel from the sulfate deposited near the outside of the spheres, whereas nickel from nitrate and chloride solutions penetrated to the interior. Reducing the time of impregnation ormore » using a wet support hindered the nickel penetration. Chromium from the nitrate and from chromic acid of low concentration was deposited near the outside of the support. If two impregnations were used consecutively, the solute from the first impregnation could redisolve and be carried towards the center of the particle during the second impregnation. This movement could be prevented by drying and calcining after the first impregnation. Catalysts impregnated with nickelous nitrate or chromic nitrate had higher pore volumes, surface areas, and pore diameters than did the support. The catalyst impregnated with nickelous sulfate had a lower surface area than the support.« less
  • An electrochemical method based on analyzing the potential-current curves, plotted at various applied P{sub O}{sub 2} for an alumina scale developed at 1100{degrees}C on a {beta}-NiAl alloy, was used to determine transport parameters in the scale. The variation of V{sub o} vs P{sub O}{sub 2} indicates that the scale consists of an inside zone characterized by an ionic-transport number t{sub i} {approximately} 0.4 and an outside part with t{sub i} {approximately} 0.1. This leads to a value of the oxygen pressure at the NiAl/Al{sub 2}O{sub 3} interface {approximately}2 x 10{sup {minus}27} atm, not far from the equilibrium value. The variationmore » of the oxygen chemical potential inside the scale was determined, showing a steep variation of {mu}{sub o} in the middle of the scale. The calculated oxidation constant is close to the experimental one, which would indicate that mainly charged species are responsible for the alumina scale growth.« less
  • A series of Co/Mo/alumina hydrodesulfurization catalysts was prepared following standard procedures, to generate an internally consistent set, wherein the content of the metal atoms was varied in a regular manner. The range in Mo compositions was 2 ..-->.. 30%; the range in Co content was 0 ..-->.. 12%. These preparations were fully characterized in the oxide state by measurements of the surface areas, pore-size distributions, diffuse reflectance spectra, and an occasional Raman spectrum. Standard activity tests were then run with light cycle oil. These values are empirically correlated with other physical characterization which primarily involve the compositions and surface areas.more » Activity tests were also run for several commercial catalysts, following a variety of regeneration and sulfurization protocols. The objective was to develop a rational model for relating activity to molecular structure, as determined from EXAFS spectra in the oxide and sulfide states.« less
