    Abstract: A method for improving deposit control and cleanliness performance in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil comprises a lubricating oil base stock as a major component, and a mixture of (i) at least one dispersant, and (ii) at least one viscosity modifier, as minor components. The at least one dispersant and the at least one viscosity modifier are present in an amount sufficient to have a critical dispersant thickening ratio of greater than 0.33. The critical dispersant thickening ratio is determined in accordance with the formula: Σ  [ G n ] *  dV  /  d  [ G n ] Σ  [ B m ] *  dV  /  d  [ B m ] wherein [Gn] is the weight percent of each of n dispersants in the formulated oil, [Bm] is the weight percent of each of m viscosity modifiers in the formulated oil, dV/d[Gn] is the kinematic viscosity (Kv100) increase of the lubricating oil per the weight percent of each of n dispersants in the formulated oil, and dV/d[Bm] is the kinematic viscosity (Kv100) increase of the lubricating oil per the weight percent of each of m viscosity modifiers in the formulated oil.

    Abstract: A method of changing container sizes on a container filling carousel, the carousel and container supports thereon, which carousel has one or more pairs of side-by-side first and second container supports, each container support having a frame, a container support platform and at least one pair of container support arms above the container support platform. Each of said container supports is structured to accept a first small-sized container. The second container support is structured to accept a second larger-sized container, relative to said first small-sized container. The carousel includes a product filling head above each of said first and second container supports. The first container support can be radially retracted from a side of the second container support and from beneath its corresponding product filling head to allow the second container support to accommodate a larger-sized container.

    Abstract: Catalyst compositions with improved alkylation activity and corresponding methods for making such catalyst compositions are provided. The catalyst(s) correspond to solid acid catalysts formed by exposing a catalyst precursor with a zeolitic framework structure to a molten metal salt that includes fluorine, such as a molten metal fluoride. The resulting fluorinated solid acid catalysts can have improved alkylation activity while having a reduced or minimized amount of structural change due to the exposure to the molten metal fluoride. This is in contrast to fluorinated solid acid catalysts that are exposed to higher severity forms of fluorination, such as exposure to ammonium fluoride or HF. SnF2 is an example of a suitable molten metal fluoride.

    Abstract: This disclosure relates to a continuous process for preparing a grease thickener product in which operating conditions of the continuous process can be varied to obtain desired grease product properties. The process includes: (a) introducing a C3 to C30 hydroxy fatty acid or a C3 to C30 hydroxy fatty acid ester, and a metal base into a reaction zone; (b) operating the reaction zone at a temperature between 100° C. and 240° C. to react the C3 to C30 hydroxy fatty acid or the C3 to C30 hydroxy fatty acid ester, and the metal base, to produce a grease thickener product; (c) introducing the grease thickener product of step (b) into a flash chamber zone; and (d) operating the flash chamber zone at a temperature sufficient to remove volatiles from the grease thickener product of step (b). The continuous process conditions afford a production throughput of grease thickener product of greater than 8,000 pounds per hour.
