  • Unclouded metals passivation additive
    Patent number: 4919840
    Abstract: Unclouded solutions of antimony hydrocarbylthiolate suitable for metals passivation are produced utilizing an amine. In one embodiment of the invention the amine is included with the antimony oxide and hydroxyhydrocarbylthiol reactants to produce the passivating agent. In another embodiment of the invention, the metals passivation additive is produced by combining antimony oxide with a hydroxyhydrocarbylthiol to produce a reaction mixture which is thereafter contacted with an amine. The resulting product is useful for the passivation of metals deposited on cracking catalysts.

  • Unclouded metals passivation additive
    Patent number: 4830730
    Abstract: Unclouded solutions of antimony hydrocarbylthiolate suitable for metals passivation are produced utilizing an amine. In one embodiment of the invention the amine is included with the antimony oxide and hydroxyhydrocarbylthio reactants to produce the passivating agent. In another embodiment of the invention, the metals passivation additive is produced by combining antimony oxide with a hydroxhydrocarbylthiol to produce a reaction mixture which is thereafter contacted with an amine. The resulting product is useful for the passivation of metals deposited on cracking catalysts.
