  • Patent number: 9518233
    Abstract: The present invention relates to a bifunctional catalyst for a hydrodewaxing process with improved isomerization selectivity, and to a method for manufacturing the same, and more particularly to a bifunctional catalyst and to a method for manufacturing same, which is characterized in that EU-2 zeolite with a controlled degree of phase transformation is used as a catalyst support having an acid site. The EU-2 zeolite, the degree of phase transformation of which is controlled, includes, by controlling synthesis parameters of EU-2, predetermined amounts of materials that are phase-transformed from EU-2 crystals such as cristobalite and quartz. The metal loaded bifunctional catalyst according to the present invention improves selectivity of the isomerization process, rather than a cracking reaction, during a hydroisomerization reaction of n-hexadecane. Therefore, the bifunctional catalyst can be widely used as a catalyst for a dewaxing process such as lubricant base oil and diesel oil.

  • Patent number: 8962901
    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 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 less carbons to a light separation process, thus obtaining olefins.

  • Publication number: 20140075055
    Abstract: A method of controlling a terminal is provided. The method includes determining a current status of at least one of the terminal and a peripheral environment of the terminal based on information obtained by using at least one sensor from a predetermined list of a plurality of statuses regarding the terminal or the peripheral environment of the terminal, determining an operation schedule of the at least one sensor based on the determined current status and the information obtained by using the at least one sensor, and controlling the at least one sensor to operate based on the determined operation schedule.
