    摘要: In the process of olefin disproportionation, a feedstock containing predominatly mono-olefin the feedstock is charged at elevated temperature into a catalytic conversion zone in contact with mesoporous acid olefin conversion catalyst under selective olefin interconversion conditions.The improvement is characterized by a mesoporous acid metallosilicate crystalline catalyst material having Bronsted acid sites in a hexagonal lattice structure, said catalyst material having substantially uniform pores in hexagonal arrangement with a pore size of about 20 to 100 Angstroms units. In the preferred embodiments the olefinic feedstock is reacted for less than 10 seconds in contact with MCM-41 mesoporous metallosilicate catalyst under partial reaction conditions sufficient to provide increased yield of C4 alkene having a ratio of isobutene to normal butenes greater than equilibrium.

    摘要: Long chain alkyl substituted aromatic compounds, particularly alkylated naphthalenes, are produced by the alkylation of aromatics, e.g. naphthalene, with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of a zeolite alkylation catalyst, preferably a large pore size zeolite such as zeolite Y and in the presence of from about 0.5 to 3.0 weight percent water, preferably 1.0 to 3.0 weight percent. The use of the water co-feed increases the selectivity of the alkylation for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products and also increases activity and catalyst stability.

The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units.A new process is provided for catalytic oligomerization of olefin feedstock which comprises contacting the feedstock under catalytic conversion conditions with acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The oligomerization reaction is very selective, especially when conducted at temperature of about 40.degree. to 250.degree. C.

The process is typically carried out at a temperatue of 200.degree. to 1000.degree. F. but the catalyst provides sufficient activity for the reaction to be carried out at temperatures below 700.degree. F. Liquid phase operation is preferred, giving a lower yield of polyethylated products. The use of the selected catalyst also results in a reduction of the xylene impurity level.

    摘要: Lubricant basestocks of high viscosity index, typically with V.I. of at least 130 or higher, and low pour point, typically below 5.degree. F., are produced by hydroisomerizing petroleum waxes such as slack wax or de-oiled wax, over zeolite beta and then dewaxing to target pour point. A preferred process employs a solvent dewaxing after the hydroisomerization step to effect a partial dewaxing with the separated waxes being recycled to the hydroisomerization step; dewaxing is then completed catalytically, typically over ZSM-5 or ZSM-23.
