  • Aluminosilicate molecular sieve
    Patent number: 6306362
    Abstract: The present invention is directed to a large-pore aluminosilicate molecular sieve comprising alumina and silica, where the ratio of SiO2/Al2O3 ranges from about 75 to 600, and its method of preparation. The large-pore aluminosilicate molecular sieve of the present invention has the ability to catalyze reactions involving particularly bulky transition states or large molecules.

  • Isoparaffinic lube basestock compositions
    Patent number: 6090989
    Abstract: A liquid hydrocarbon composition, containing paraffinic hydrocarbon components in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching, as measured by the percentage of recurring methylene carbons which are four or more carbons removed from an end group or branch (CH.sub.2 >4), are such that:(a) BI-0.5(CH.sub.2 >4)>15; and(b) BI+0.85(CH.sub.2 >4)<45as measured over said liquid hydrocarbon composition as a whole.
