  • Patent number: 6110357
    Abstract: A zeolite-containing cracking catalyst is passivated with compounds of boron and zirconium, and preferably also antimony. The thus-passivated cracking catalyst is employed in a process for catalytically cracking a hydrocarbon-containing oil feed. In another embodiment, compounds of boron and zirconium, and preferably also antimony, are added to a hydrocarbon-containing oil feed which is catalytically cracked in the presence of a zeolite-containing cracking catalyst.

  • Patent number: 5389233
    Abstract: A zeolite-containing cracking catalyst is passivated with lithium sulfate and, preferably, at least one additional passivating agent (more preferably at least one antimony compound). The thus-passivated cracking catalyst is employed in a process for catalytically cracking a hydrocarbon-containing oil feed. In another embodiment, lithium sulfate and, preferably, at least one additional passivating agent are added to a hydrocarbon-containing oil feed which is catalytically cracked in the presence of a zeolite-containing cracking catalyst.

  • Patent number: 5256742
    Abstract: A process for preparing a poly(arylene sulfide) and copolymer thereof from a poly(arylene sulfide disulfide) is provided which comprises contacting the poly(arylene sulfide disulfide) with a polyhalo-substituted cyclic compound having unsaturation between adjacent ring carbon atoms and having halogen atoms attached to the ring carbon atoms in a polar organic compound and a basic compound at an elevated temperature. Alternatively, the poly(arylene sulfide disulfide) can be substantially dissolved in the polar organic solvent at elevated temperature to form fragments which can be contacted with the polyhalo-substituted cyclic compound in a polar organic compound and a basic compound at an elevated temperature. The fragments also can be isolated, recovered and then contacted with the polyhalo-substituted cyclic compound in a polar organic compound and a basic compound at an elevated temperature.
