The present invention relates to a novel polypouch for packaging of mineral oils. Said polypouch is made up of multilayered polymeric sheet or film of different inventive thicknesses by co-extruded unique combination of low density polyethylene, nylon and adhesive resin resulting in negligible permeation loss of packed mineral oils e.g. kerosene oil.

The present invention relates to a adsorbent composition for removing refractory sulphur compounds from refinery streams comprising of base component in the range of 10 to 50 wt %, spinel oxide in the range of 20 to 60 wt % as a reactive metal oxide component and bimetallic alloy in the range of 10 to 40 wt % acting as an adsorption enhancer component, wherein the adsorption enhancer component acts in synergy with base component. The invention also relates to a process for the preparation of said composition by mixing in solid state fine particles of base component, spinel oxide and bimetallic alloy, homogenizing the mixture thus obtained with solvent, peptizing the wet solid with dilute mineral acid, extruding the peptized material with extrusion aiding agents, drying the extrudates, further calcining the dried extrudates and reducing the calcined material under hydrogen flow.

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.

An apparatus for separating impurities from a liquid by a non-dispersive contacting of a liquid&#x2014;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.

Device and method for non-dispersive contacting of liquid&#x2014;liquid reactive system

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 &#x212b;) 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.
