| 436060000 | LUBRICANT, GREASE, MINERAL OIL, HYDROCARBON OIL PRODUCT, OR FATS OR LIPIDS FOR OXIDATION (E.G., BREAKDOWN PRODUCTS OR CONTAMINATION, ETC.) | 10 |
| 20130115704 | SYSTEM AND METHOD FOR THE ANALYSIS OF BIODIESEL - Methods and devices are disclosed providing techniques for measuring the amount of biodiesel in a fuel sample. The methods may be used in the field without the use of laboratory equipment. The biodiesel in the sample is converted to the corresponding free acid which can be isolated and quantified to provide information regarding the amount of biodiesel in the original sample. | 05-09-2013 |
| 20080206878 | Method of Analyzing Basestocks For Low Temperature Properties - A process for producing lube basestocks involving solvent dewaxing a waxy feed to produce at least a partially dewaxed lube oil boiling range stream and then hydrodewaxing the partially dewaxed lube oil boiling range stream to produce a lube basestock. | 08-28-2008 |
| 20080206879 | Analysis of Functional Fluids Using a Redox Indicator - The present invention relates to the analysis of the quality of functional fluids. In particular, the invention relates to using a stable redox indicator that produces a color at the presence of oxidation byproducts in a functional fluid. | 08-28-2008 |
| 20090029475 | METHOD FOR DETERMINING THE CONTENT OF DIESEL FUEL IN A LUBRICATING OIL OF A COMBUSTION ENGINE - A method for determining proportion of diesel fuel in a lubricating oil of a combustion engine, including: forming a mixture containing an oil sample and a C | 01-29-2009 |
| 20090117659 | Process for Evaluating Quality of Coke and Bitumen of Refinery Feedstocks - This invention relates to processes for the evaluation of the coke and/or bitumen quality of a plurality of refinery feedstocks using high throughput experimentation. | 05-07-2009 |
| 20100120158 | METHOD FOR ANALYZING PETROLEUM-BASED FUELS AND ENGINE OILS FOR BIODIESEL CONTAMINATION - A method for detecting contamination of a conventional petroleum-based fuel used in an internal combustion engine is provided. A sample of engine oil is separated into a polar component and a non-polar component by a polar solvent. The polar component is analyzed for one or more biodiesel chemical components selected from the group consisting of plant sterols, fatty acid methyl esters, cetane, and combinations thereof, which relate to a degree of engine oil contamination. The polar and non-polar component may be analyzed by Gas Chromatography and Mass Spectrometry (GC/MS) and optionally Flame Ionization Detection (FID) for the one or more biodiesel chemical components, which can provide a semi-quantitative level of such biodiesel chemical components. Fuel samples can also be analyzed for biodiesel contamination species via GC/MS. | 05-13-2010 |
| 20080199962 | Qualitative Assay of Extra-Virgin Olive Oils - A methodology that enables introduction of an innovative assay for evaluating the extra-virgin olive oil (EOO), based upon the quantification of the main components of the saponifiable and non-saponifiable fractions of EOOs and upon its total antioxidizing power. | 08-21-2008 |
| 20110020940 | Marker Dyes for Petroleum Products - The present invention relates to using a marker in a functional fluid, which survives the use of the functional fluid in an application, with a reagent solution to identify the functional fluid rapidly either before, during or after the functional fluid's use and which is a suitable method for identifying a functional fluid in the field, and which may employ the use of test wipe, or medium, that contains the reagent solution. | 01-27-2011 |
| 436061000 | Acidity, basicity or neutralization number | 2 |
| 20110059532 | MONITORING OF FRYING OIL QUALITY USING COMBINED OPTICAL INTERROGATION METHODS AND DEVICES - Herein are disclosed methods and devices for optically monitoring multiple parameters of an oil sample. In one embodiment, the methods and devices can be used for determining the quality of cooking or flying oil in terms of the free fatty acid content and total polar compound content of the oil. The methods use an optical absorbtive/reflective property in evaluating the free fatty acid content, and use optical fluorescence in evaluating the total polar compound content, with both measurements using a single sampling substrate and a single measuring device. | 03-10-2011 |
| 20080199963 | Method of Determining Acid Content - A method for determining the TAN value of a hydrocarbon-containing composition, in which the sample is cleared of free water, heated to an elevated temperature in an oxygen free environment, conditioned at the elevated temperature for an extended period of time, cooled down to a temperature near to room temperature, and titrated against alcoholic potassium hydroxide, whereby the TAN value may be calculated. | 08-21-2008 |
