Abstract: This invention relates to a method of producing an aromatic hydrocarbon compound from byproducts of aromatic carboxylic acid and/or aromatic carboxylic acid alkylester preparation processes using hydroprocessing under conditions of high temperature and high hydrogen pressure in the presence of a catalyst, and to a hydroprocessing catalyst used therein.

Abstract: Disclosed is a catalyst including metal phosphide for preparation of biodiesel, and a method of preparing biodiesel from feedstock comprising vegetable oil through hydrotreating using the catalyst. When the catalyst including metal phosphide is used as a catalyst for preparation of biodiesel, preparation activity of hydrotreated biodiesel is high even without continuous supply of sulfiding agent, and hydrotreating and isomerization reactions occur at the same time, thus obtaining high-quality hydrotreated biodiesel having a low pour point.

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: The present invention relates to a hydroprocessing catalyst comprising: (i) one or more hydrogenation metal components selected from a group consisting of VIB group metal, VIIB group metal and VIII group metal; and (ii) an organic compound expressed by the following chemical formula 1 or an organometallic compound expressed by the following chemical formula 2. Chemical formula 1: R1COCH2COR2 (wherein, R1 and R2 are the same or different from each other, and are one or more groups selected from a group consisting of C1 to C12 alkyl, C6 to C12 allyl, C1 to C12 alkoxy and hydroxy). Chemical formula 2: X(R1COCH1COR2)n (wherein, X is selected from a group consisting of VIB group metal, VIIB group metal and VIII group metal, R1 and R2 are the same or different from each other, and are one or more groups selected from a group consisting of C1 to C12 alkyl, C6 to C12 allyl, C1 to C12 alkoxy and hydroxy, and n is an integer of 1 to 6).

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: This invention relates to a method of producing aromatics and olefins from oils derived from coal or wood, including partially saturating and cracking the oils derived from coal or wood in a hydrogenation & reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation & 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 less carbons to a light separation process, thus obtaining olefins.

Abstract: Methods are provided for verifying whether a mobile device is at a site. An exemplary method involves obtaining a location of the mobile device from the mobile device and obtaining a captured value for a machine-readable code from one of the mobile device and the site, the machine-readable code being presented by the other of the mobile device and the site. When the captured value is equal to a reference value for the code, the mobile device is verified as being at the site when the location of the mobile device corresponds to a location associated with the site.
