  • Process for preparing catalyst supports having reduced levels of contaminant
    Patent number: 8389437
    Abstract: A method of preparing a catalyst support is described comprising washing a precipitated metal oxide material with water and/or an aqueous solution of acid and/or base such that contaminant levels in said precipitated metal oxide are reduced. The method may be applied to precipitated alumina materials to reduce contaminants selected from sulphur, chlorine, Group 1A and Group 2A metals. The catalyst supports may be used to prepare catalysts for the Fischer-Tropsch synthesis of hydrocarbons.
    Type: Grant
    Filed: July 18, 2011
    Date of Patent: March 5, 2013
    Assignee: Johnson Matthey PLC
    Inventors: John L. Casci, Elizabeth M. Holt, Adel F. Neale

  • Heteroarotinoid compounds as anticancer agents
    Patent number: 4826984
    Abstract: Novel heteroarotinoid compositions characterized by the formulae: ##STR1## where R is H, CH.sub.3 or C.sub.2 H.sub.5 and X is S, S O, O, NCH.sub.3, Si(CH.sub.3).sub.2, N.sup.+ (H)CH.sub.3 [Cl.sup.- ], N.sup.+ (H)CH.sub.3 [Br.sup.- ] or N.sup.+ (alkyl) CH.sub.3 [Cl.sup.- or Br.sup.-) where alkyl is CH.sub.3, C.sub.2 H.sub.5, CH.sub.2 .dbd.CHCH.sub.2 or C.sub.6 H.sub.5 CH.sub.2. Such compositions exhibit activity as anticancer agents.
