    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: 8877670
    Abstract: Catalysts are disclosed comprising fibrous substrates having silica-containing fibers with diameters generally from about 1 to about 50 microns, which act effectively as “micro cylinders.” Such catalysts can dramatically improve physical surface area, for example per unit length of a reactor or reaction zone. At least a portion of the silica, originally present in the silica-containing fibers of a fibrous material used to form the fibrous substrate, is converted to a zeolite (e.g., having a SiO2/Al2O3 ratio of at least about 150) that remains deposited on these fibers. The fibrous substrates possess important properties, for example in terms of acidity, which are useful in hydroprocessing (e.g., hydrotreating or hydrocracking) applications.

  • Patent number: 8778171
    Abstract: This invention relates to hydrocracking catalysts utilizing stabilized aggregates of small primary crystallites of zeolite Y that are clustered into larger secondary particles. At least 80% of the secondary particles may comprise at least 5 primary crystallites. The size of the primary crystallites may be at most about 0.5 micron, or at most about 0.3 micron, and the size of the secondary particles may be at least about 0.8 micron, or at least about 1.0 ?m. The silica to alumina ratio of the resulting stabilized aggregated Y zeolite may be 4:1 or more. This invention also relates to the use of such catalysts in hydrocracking processes for the conversion of heavy oils into lighter fuel products. The invention is particularly suited for the selective production of diesel range products from gas oil range feedstock materials under hydrocracking conditions.

  • Patent number: 8617383
    Abstract: An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or with only a high pressure separation so that the dewaxing still occurs under sour conditions. Various combinations of hydrotreating, catalytic dewaxing, hydrocracking, and hydrofinishing can be used to produce fuel products and lubricant base oil products.
