Abstract:
This invention relates to a hydrocracking catalyst for preparing valuable light aromatic hydrocarbons from polycyclic aromatic hydrocarbons derived from oil, which includes (i) beta-zeolite, (ii) pseudo-boehmite, and (iii) one or more metals selected from among metals of Groups VIII and VIB, and which further includes a cocatalyst component, thereby producing a maximum amount of BTX (Benzene, Toluene, Xylene) from LCO (Light Cycle Oil).
Abstract:
Disclosed is a method of simultaneously manufacturing high quality naphthenic base oil and heavy base oil using a single catalyst system, by subjecting an oil fraction (slurry oil or light cycle oil) produced by fluid catalytic cracking and an oil fraction (deasphalted oil) produced by solvent deasphalting to hydrotreating, catalytic dewaxing and hydrofinishing of the single catalyst system, thereby obtaining not only products having low viscosity but also heavy base oil products (150BS) having high viscosity which was impossible to obtain using a conventional catalytic reaction process, and also thereby producing base oil products having different properties using the single catalyst system, thus generating economic benefits and exhibiting superior efficiency.
Abstract:
Disclosed is a method of manufacturing high-quality naphthenic base oil from oil fractions having a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. This method enables the high-quality naphthenic base oil to be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive and have a high aromatic content and a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit, and the method also improves the pretreatment process of a feedstock, and thus the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced, thereby mitigating extreme operating conditions, increasing the lifetime of a catalyst, and producing various high-quality naphthenic base oil products in high yield.
Abstract:
The present invention relates to a method for preparing biodiesel by isomerizing a part of the resultant of hydrodeoxygenation and recycling the isomerized product, and then hydrodeoxygenating a fresh feed in a diluted state again when oxygen is removed in the form of water, CO, and CO2 by adding hydrogen to a feed including triglyceride (TG).
Abstract:
Provided is a method for reducing the amount of organic acids in a hydrocarbon oil fraction by hydrogenating the organic acids in the hydrocarbon oil fraction under mild conditions. Provided is a new method able to overcome the problem of organic-acid-induced corrosion during the process of distillation, by using hydrogen or a hydrogen-containing mixed gas and a hydrogenation catalyst to subject the organic acids in the hydrocarbon oil fraction to hydrogenation at an appropriate temperature and pressure, thereby converting the same to hydrocarbons and so reducing the amount of organic acids in the hydrocarbon oil fraction.
Abstract:
The present invention relates to a method for preparing an organic phase-change material (PCM) by means of a hydrotreating reaction of animal and plant oils. The method for preparing an organic phase-change material according to the present invention can enable the preparation of a high-purity organic phase-change material in an inexpensive manner as compared to conventional preparation methods in which organic phase-change materials are obtained from kerosene through absorption and desorption processes.
Abstract:
This invention relates to a method of producing aromatics and light paraffins from hydrocarbonaceous oils derived from oil, coal or wood, including partially saturating and hydrocracking the oils derived from oil in a hydrogenation and reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation and reaction area, feeding oils suitable for producing BTX to an aromatic separation process and a transalkylation process to recover aromatics, and feeding hydrocarbonaceous components having 5 or fewer carbons to a light separation process, thus obtaining light paraffins.
Abstract:
Disclosed herein is a catalyst for producing biodiesel, including a carrier having water resistance and an active component supported on the carrier and used in a hydrotreating reaction or a decarboxylation reaction. Since the catalyst for producing biodiesel includes a carrier having strong water resistance, the deactivation of the catalyst due to the water produced through a process of producing HBD can be prevented, thus remarkably improving the long term stability of a catalyst.
Abstract:
The present invention relates to a catalyst for preparing biodiesel, and a method for preparing biodiesel using the same. More specifically, the present invention relates to a catalyst for preparing biodiesel, which prepares biodiesel from a feed containing vegetable oil using a catalyst containing a metal phosphorus compound. The catalyst for preparing biodiesel according to the present invention uses a metal phosphorus compound, thereby enhancing preparation activity of HBD even without continuous injection of sulfides, and enabling production of high quality HBD with a low pour point due to the simultaneous procession of hydrogenation and isomerization reactions.
Abstract:
The present invention relates to a method for producing aromatic products (benzene/toluene/xylene) and olefin products from oils produced by a fluidized catalytic cracking process. More particularly, the present invention relates to a method for producing high concentration aromatic products and high value light olefin from light cycle oil produced by a fluidized catalytic cracking process.
