  • Patent number: 4883782
    Abstract: A thin film catalyst structure is described for use in hydrodesulphurization of gaseous hydrocarbon mixtures. The catalyst is formed starting with an aluminum substrate having an oxide surface layer and thin films of metallic cobalt and molybdenum are sequentially deposited on the aluminum oxide layer. The films of metallic cobalt and molybdenum are calcined and then reduced and sulphided to form a sulphided thin film catalyst structure having improved hydrodesulphurization properties.

  • Patent number: 4611120
    Abstract: A method of suppressing molecular ions in the secondary ion mass spectra of conducting, semiconducting and insulating specimens is described using a commercial secondary ion microscope/mass analyzer with unconventional primary beam conditions and uncoated samples, so as to almost eliminate the contribution of molecular ions to the mass spectrum. This results in excellent discrimination for major and trace element detection in these materials, including for example complete resolution of the rare earth elements in a number of minerals. Complete elemental analysis for a much enhanced range of elements down to the ppb level is now possible. The method also facilitates the analysis of insulating materials which would undergo surface charging distortion under any other condition.
