  • Patent number: 11970732
    Abstract: The present invention relates to a method for determining the DNA quality of a biological sample and, more specifically, to a method for determining the DNA quality of a biological sample by performing a quantitative polymerase chain reaction (PCR) using primers capable of amplifying a target gene, a method for preparing the primers used in the method, and a method for standardizing the amount of detected target gene mutation by using the determined DNA quality. The method of the present invention enables objective evaluation of the DNA quality of a biological sample used in gene analysis and the presentation of objective results on the expression ratio of a gene mutation, thereby providing reliable information in the fields of clinical research and companion diagnosis.

  • Patent number: 8691076
    Abstract: Disclosed is a method of manufacturing high-quality naphthenic base oil by subjecting, as a feedstock, light cycle oil (LCO) and slurry oil (SLO) obtained through fluidized catalytic cracking (FCC) to hydrotreating and dewaxing.

  • Patent number: 8585889
    Abstract: A method of manufacturing high-quality naphthenic base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. High-quality naphthenic base oil may be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive, and have a high aromatic content, a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit. The method also relates to the pretreatment process of a feedstock, where the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced.

  • Publication number: 20100193400
    Abstract: Disclosed herein is a method of producing feedstock of high-quality lube based oil by producing coker gas oil (CGO) from vacuum residue (VR) or a mixture (VR/AR) of atmospheric residue (AR) and vacuum residue (VR), performing a hydrotreating process and a hydrocracking process by mixing the coker gas oil (CGO) with vacuum gas oil (VGO) to form unconverted oil (UCO), and then recycling the unconverted oil. The method of producing feedstock of high-quality lube based oil is advantageous in that feedstock of high-quality lube based oil can be more economically and efficiently produced using cheap coker gas oil (CGO), which is hard to treat.

  • Publication number: 20090050524
    Abstract: The present invention relates to a method of producing a feedstock for high-quality lube base oil from unconverted oil (UCO) obtained from fuel oil hydrocracking, and more particularly to a method of producing a feedstock for high-quality lube base oil by treating vacuum gas oil (VGO) or a mixture of vacuum gas oil (VGO) with coker gas oil (CGO) or deasphalted oil (NAO) as a feedstock in a hydrotreating unit and a first hydrocracking unit and recycling the resulting unconverted oil (UCO) through a second hydrocracking unit.
