This invention relates to a method of producing aromatic hydrocarbons and olefin from hydrocarbonaceous oils including large amounts of polycyclic aromatic compounds having two or more rings via partial hydrogenation in the presence of a hydrogenation catalyst and catalytic cracking in the presence of a catalytic cracking catalyst.

Method of producing aromatic hydrocarbons and olefin from hydrocarbonaceous oils comprising large amounts of polycyclic aromatic compounds

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).

Hydrocracking catalyst for preparing valuable light aromatic hydrocarbons from polycyclic aromatic hydrocarbons

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.

Disclosed herein is a method of producing an optically active thiophene-based compound using a simulated moving bed adsorption separation process, and more specifically, a method of continuously separating a racemic thiophene-based compound into its optically active thiophene-based compounds having high purity, through optical resolution using the simulated moving bed process. According to the method of the current invention, a racemic mixture of a thiophene-based compound can be continuously separated into its optically active thiophene-based compounds having high purity, which is an intermediate of optically active dorzolamide acting as a topical therapeutic agent for glaucoma, using a simulated moving bed adsorption separation technique, thereby increasing industrial usability.
