    摘要: The conversion of hydrocarbons in the presence of hydrogen occurs under hydrocarbon conversion conditions in the presence of a subgroup of a certain class of metal-substituted semi-crystalline aluminosilicates which are synthetic and which are predominantly ordered in two directions, that is, which are laminar or have a layered or stacked sheet structure. The metal substituted for the aluminum in the trioctahedral sites is nickel, cobalt, or mixtures thereof. Hydrocarbon conversion catalysts are also claimed comprising the metal-substituted laminar 2:1 layer lattice aluminosilicate minerals containing in addition a hydrogenation component such as palladium. The catalysts are preferably used in hydroisomerization and hydrocracking processes.

    摘要: Describes a free flowing particulate composition comprising, in combination, particulate amorphous precipitated silica, e.g., in the form of granules, hydrocarbon process oil, e.g., an aromatic process oil, and organic carboxylic acid having from 2 to 30 carbon atoms, e.g., stearic acid. The hydrocarbon process oil and organic carboxylic acid are sorbed on the silica and are present in amounts sufficient to measurably improve the dispersibility of the particulate amorphous precipitated silica into an elastomer as measured by percent white area. Optionally, an organosilane coupling agent may also be present in said composition. The free flowing particulate composition of the present invention is useful in reinforcing elastomers, e.g., rubbers used in vehicle tires and the soles of athletic foot wear.
