摘要:
The present invention provides a fuel additive composition for stabilizing blends of ethanol and a hydrocarbon boiling in the gasoline or diesel range, comprising: a) 0.1-10% of Cashew Nut Shell Liquid (CNSL) derivative(s) or mixtures thereof of formula (I) where m=0-12, n=0, 2, 4 & 6 and b) 0.1-10% of an organic co-solvent depending upon the percentage composition of diesel and ethanol blend.
摘要:
The present invention relates a surfactant composition for use as an emulsifier in water blended fuel mtixture. The said composition includes ethoxylate of cashew nut shell liquid. In addition ethoxylate of cashew nut shell liquid, the said composition comprises a co-surfactant having a hydrophilic lipophilic balance in the range of 4 to 12 and a polymeric dispersant. The water blended fuel mixture using emulsifers of the present invention, overcome some of the shortcomings of the previously known emulsions. The ethoxylate of cashew nut shell liquid is of the formula (I).

摘要:
The present invention relates to the process for the preparation of Polymer/Food grade hydrocarbon solvents of naphtha range essentially free from olefins less than 20 ppm of aromatics and less than 1 ppm of sulfur from paraffinic-rich low value streams such as raffinate from the solvent extraction units in crude oil refineries employed for recovery of aromatics from reformate by hydrogenation in the presence of a nickel based catalyst.
摘要:
Disclosed herein is a single pot process for producing biodiesel and the product thereof, using non-edible oil sources containing free fatty acid. The process comprises esterification and transesterification of non-edible vegetable oil sources containing free fatty acids in a single pot employing a water scavenger or a water adsorbent or a mixture thereof.
摘要:
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.
摘要:
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.
摘要:
An apparatus for separating impurities from a liquid by a non-dispersive contacting of a liquid-liquid reactive systems, said liquids being immiscible with each other, which comprises 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 said column on a support, a first distributor provided in the first stage of the column for distributing a first liquid located above said support such that said first liquid completely wets said 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 said second liquid flow co-currently with said first liquid so that the impurities present in said second liquid react with said first liquid and dissolve therein and a separator connected to a bottom of said column for separating the first liquid and purified second liquid.
摘要:
The invention provides a simple method for isolation of calliterpenone (16α,17 dihydroxy-3-oxo phyllocladane), a phyllocladane diterpenoid with the plant growth regulating properties, from plant genus Callicarpa.
摘要:
The invention relates to a novel pharmaceutical composition comprising an effective amount of bio-active fraction from cow urine distillate as a bioavailability facilitator and pharmaceutically acceptable additives selected from anticancer compounds, antibiotics, drugs, therapeutic and nutraceutic agents, ions and similar molecules which are targeted to the living systems.
