  • Removal of trialkyl arsines from fluids
    Patent number: 4992620
    Abstract: Trialkyl arsines are removed from fluids, in particular gases, by contacting with a solid sorbent material containing at least one manganese oxide (preferably MnO.sub.2) and at least one Group IB metal oxide (preferably CuO). In a preferred feature, the used solid sorbent material is regenerated by oxidizing treatment, washing with an aqueous liquid, and drying.
    Type: Grant

  • Pretreatment of butenes
    Patent number: 4849576
    Abstract: In a process for isomerizing monoolefins having a terminal double bond (in particular the isomerization of butene-1 to butene-2) in the presence of a Group VIII metal catalyst (in particular an alumina-supported Pd catalyst) which is contaminated by impurities in the monoolefin containing feed, the improvement comprises pretreating the feed with a solid material comprising tin oxide and a refractory support material (in particular alumina).
