  • Publication number: 20090182183
    Abstract: A process for the oligomerization of propylene is disclosed wherein a tungstated zirconia catalyst prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms useful for preparing neo acids.

    Abstract: Provided is a process for oligomerizing n-olefins. The process has the step of reacting (oligomerizing) an amount of one or more n-olefins in the presence of a catalytically effective amount of a two or more metal oxides at a temperature effective to effect oligomerization. The two or more metal oxides are represented by the formula MOn/M?On?. M and M?, are, independently, selected from the group consisting of Al, Ce, Fe, P, W, Zr, and combinations thereof. M and M? are different metals or combinations of metals. “n” and “n?” are positive numbers and vary stoichiometrically depending on the valency of M and M?, respectively. Provided is also a process for alkylation of an alkylatable aromatic compound. The process has the step of contacting an amount of one or more n-olefins with an amount of aromatic compound in the presence of a catalytically effective amount of the two or more metal oxides at a temperature effective to effect alkylation of the aromatic compound.

    Abstract: EMM-3 (ExxonMobil Material number 3) is a new crystalline microporous material with a framework of tetrahedral atoms connected by atoms capable of bridging the tetrahedral atoms, the tetrahedral atom framework being defined by the interconnections between the tetrahedrally coordinated atoms in its framework. EMM-3 can be prepared in aluminophosphate (AlPO) and metalloaluminophosphate (MeAPO) compositions with the hexamethonium template. It has a unique X-ray diffraction pattern, which identifies it as a new material. EMM-3 is stable to calcination in air, absorbs hydrocarbons, and is catalytically active for hydrocarbon conversion.

  • Patent number: 6984761
    Abstract: A process is disclosed for producing ?-methylstyrene, acetone, and phenol wherein the amount of ?-methylstyrene produced may be controlled by selectively converting a portion of the cumene hydroperoxide to dimethyl phenyl carbinol, the hydrated form of ?-methylstyrene. The dimethyl phenyl carbinol thus produced will lead to increased production of ?-methylstyrene upon dehydration in the acid cleavage unit of the phenol plant. By controlling the fraction of the cumene hydroperoxide reduced to dimethyl phenyl carbinol, the amount of ?-methylstyrene produced in the plant can be continuously set to meet the demand of the market for ?-methylstyrene. Also disclosed is a non-acidic catalyst for reduction of cumene hydroperoxide.
