Abstract: Lubricating grease compositions have a titanium complex grease component along with a mineral/synthetic oil-based component and a conventional soap or grease. The conventional soaps and greases may be lithium complex, calcium sulfonate, or aluminum complex-based, among others, with and without additives. The compositions are high performance geases, exhibiting improved drop point, extreme pressure, antiwear, oil separation, and shelf life properties.

Abstract: Disclosed herein is a bio-assisted method for treatment of hydrocarbon contaminated soil employing novel microbes which are capable of decontaminating hydrocarbon contaminated soil having free flowing water or in slurry form or having large amount of gravels. The method comprises adding hydrocarbon releasing microbes followed by adding the microbes capable of degrading the released hydrocarbon to decontaminate the soil, wherein said microbes are grown separately in suitable vessels containing a suitable nutrient medium.

Abstract: An apparatus for separating impurities from a liquid by a non-dispersive contacting of a liquid—liquid reactive systems, the liquids being immiscible with each other, having a cylindrical column separated into a first stage and a second stage, a plurality of modules of packed metallic fibers mounted in the first stage of the column on a support, a first distributor provided in the first stage of the column for distributing a first liquid located above the support such that the first liquid completely wets the fibers by capillary action and forms a film thereon, a second distributor fitted at a bottom portion of the second stage for distributing a second liquid containing impurities on to the metallic fibers, wherein the second liquid flows concurrently with said first liquid so that the impurities present in the second liquid react with the first liquid and dissolve therein and a separator connected to a bottom of said column separates the first liquid and purified second liquid.

Abstract: A process for the preparation of hydrotreating catalyst which comprises of a Group VIB metal and Group VIII metal on an active composite carrier for the removal of sulfur from gas oil feed stocks, wherein the said carrier comprises of a phosphated alumina and an ultra stable Y zeolite and the metal components mostly reside on the alumina, said process comprising the steps of impregnation of chelated metal complex preferentially on to the alumina component of the composite support and subjecting the composite catalyst to a high-speed ball milling. The catalyst obtained by the process of the present invention consists of the active metals in the nanoparticle range (less than 50 ?) while also retaining the zeolite properties of the composite carrier and the catalyst produces less than 50 ppm sulfur from gas oil feed stocks containing greater than 1 wt % sulfur under typical commercial operating conditions.
