    摘要: A catalytic process is provided for the preparation of dialkylnaphthalenes by alkylating a 2-alkylnaphthalene with an alkylating agent having an aliphatic group of from one to five carbon atoms, such as methanol. The catalyst comprises a synthetic zeolite characterized by an X-ray diffraction pattern including interplanar d-spacings at 12.36.+-.0.4, 11.03.+-.0.2, 8.83.+-.0.14, 6.18.+-.0.12, 6.00.+-.0.10, 4.06.+-.0.07, 3.91.+-.0.07 and 3.42.+-.0.06 Angstroms.

    摘要: The present invention relates to the removal of mercury and other heavy metals from a hydrocarbon feedstream. The process involves contacting the hydrocarbon feedstream with a feedstream-soluble sulfur compound and then contacting the hydrocarbon feedstream and solubilized sulfur compound with an adsorbent.

    摘要: Petroleum wax feeds having a low oil content are converted to high viscosity index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to lube range products of between generally 30 and 40 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 800 psig using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity zeolite beta catalyst. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite beta catalyst. The second stage is carried out at relatively low temperature, typically from 600.degree. to 650.degree. F. A final dewaxing step to target pour point may be used.
