Abstract: A lubricating oil composition employable in combination with a low sulfur content fuel oil is preferably composed of a base oil having a sulfur content of at most 0.2 wt. %, an ashless dispersant comprising an alkenyl- or alkyl-succinimide or a derivative thereof, a metal-containing detergent containing an organic acid metal salt, a zinc dialkyldithiophosphate, a zinc dialkylaryldithiophosphate, and an oxidation inhibitor selected from the group consisting of a phenol compound, an amine compound, and a molybdenum-containing compound, wherein a ratio of the phosphorus content of the zinc dialkyldithiophosphate to the phosphorus content of the zinc dialkylaryldithiophosphate is in the range of 20:1 to 2:1.

Abstract: The present invention provides a method for preparing a zeolite having lattice substituted heteroatoms. The method includes: (a) contacting a calcined borosilicate zeolite with an acid, thereby producing an at least partially deboronated zeolite; and (b) contacting the at least partially deboronated zeolite with a salt-containing aqueous solution comprising one or more salts selected from the group consisting of aluminum salt, gallium salt, and iron salt, thereby producing a silicate or borosilicate zeolite having a lattice comprising aluminum atoms; gallium atoms, iron atoms or a combination thereof. Step (b) is conducted at a pH of about 3.5 or less. Preferably, step (a), step (b) or both are conducted at a temperature of from about ambient temperature to about 300° C., preferably, under stirring/tumbling.

Abstract: A diesel fuel having at least 50% C10 to C20 paraffins, wherein the iso-paraffin to normal paraffin mole ratio is up to 21:1 and higher. This diesel fuel can be produced from a feed containing at least 90% C10+ normal paraffins. This diesel fuel is produced by contacting a feed in an isomerization reaction zone a feed with a catalyst comprising a SAPO-11 and platinum in the presence of hydrogen (hydrogen:feed ratio of from 1,000 to 10,000 SCFB) at a temperature of from 340° C. to 420° C., a pressure of from 100 psig to 600 psig, and a liquid hourly space velocity of from 0.1 hr−1 to 1.0 hr−1.

Abstract: A process for preparing an ethylene-rich composition from a C3-5 paraffinic feedstock is described. The C3-5 paraffinic feedstock is subjected to molecular redistribution via dehydrogenation to form olefins, metathesis of the olefins, and rehydrogenation of the olefins to form paraffins. The product stream includes ethane, which is isolated and sent to an ethane or ethane/propane cracker (or, alternatively, a flexi-cracker, although this is less cost effective) to yield an ethylene-rich composition. The product stream also includes C3-5 paraffins, which can be recycled, and C6+paraffins, which can be used, for example, as solvents. Alternatively, they can be isomerized to form gasoline additives, or can be converted to aromatic compounds by subjecting them to reforming conditions, for example using the AROMAX™ process or platforming or rheniforming conditions.
