20090306850 | System for monitoring DPF using wireless communication - The present invention relates to a system for monitoring DPF which can inform a point of time for regenerating the DPF to a driver. The system for monitoring DPF using wireless communication, which comprises a filter for gathering PM (Particulate Matter) and at least one or more pressure sensors and temperature sensors, comprises a monitoring part and a server system. | 12-10-2009 |
20130224090 | CATALYST FOR SELECTIVE OXIDATION OF NH3 TO N2 AND METHOD FOR PREPARING THE SAME - Disclosed is a catalyst which can convert ammonia contained in exhaust gas from an engine of a vehicle equipped with a Urea-SCR (Urea-Selective Catalytic Reduction) system, to nitrogen, and a method for preparating the same. The catalyst can convert ammonia which is failed to participate in a conversion reaction of NOx to N2 and slipped out of the SCR catalyst, to nitrogen via a SCO (Selective Catalytic Oxidation) reaction, before the ammonia is released to the air. | 08-29-2013 |
20150336084 | Catalytic Cracking Catalyst for RFCC Process with Maximized Diesel Yields and a Method for the Preparation Thereof - The present invention relates to a catalytic cracking catalyst for RFCC process with maximized diesel yield which includes a clay matrix and an inorganic oxide, wherein pores with a diameter greater than 20 Å are controlled, to be greater than 80% by volume of the total pore count of the catalyst, and a method for the preparation thereof. | 11-26-2015 |
20150337219 | RFCC Process with Maximized Diesel Yields - The present invention relates to a RFCC process. More specifically, the present invention relates to a RFCC process with maximized diesel yield which includes catalytically reacting a catalytic cracking catalyst in which zeolite has been selectively removed, with a petroleum feedstock in a reaction zone of a fluidized bed catalytic cracking unit to thereby obtain a product stream, an unreacted petroleum feedstock and a mixture of the used catalysts, and separating and collecting the product stream from the used catalyst and the unreacted petroleum feedstock. | 11-26-2015 |
20150368537 | METHOD OF PREPARING DRILLING FLUID AND LUBE BASE OIL USING BIOMASS-DERIVED FATTY ACID - Disclosed is a method of preparing a drilling fluid and lube base oil using biomass-derived fatty acid, including hydrogenating a fatty acid mixture derived from fat of biological origin so as to be converted into a fatty alcohol mixture, which is then dehydrated to give a C16 and C18 linear internal olefin mixture, which is then oligomerized to give olefinic lube base oil, followed by hydrofinishing to remove the olefin, yielding high-quality lube base oil (e.g. Group III or higher lube base oil). The C16 and C18 linear internal olefin mixture, which is a reaction intermediate, can be utilized as a high-quality drilling fluid. | 12-24-2015 |
20160097014 | Lube Base Oil Comprising X-Type Diester Acid Dimer and Method for Preparing the Same - The present invention relates to a preparation method of a lube base oil including a conversion of biomass fat to a fatty acid; a separation of a C18 unsaturated fatty acid from the fatty acid; a maximization of an oleic acid content through partial hydrotreating of the C18 unsaturated fatty acid; a synthesis of a dimer or higher-order oligomer through an oligomerization of the oleic acid; and an esterification of the oligomer, and relates to a lube base oil prepared therefrom. The lube base oil of the present invention contains an x-type diester dimer and has an excellent low-temperature stability and a high biodegradability resulting from its chemical structure, thus being ecofriendly. | 04-07-2016 |
