A method including subjecting an ultra-stable Y-type zeolite having a low silica-to-alumina molar ratio (SAR), such as in a range of 3 to 6, to acid treatment and heteroatom incorporation contemporaneously to give a framework-modified ultra-stable Y-type zeolite.

Manufacturing hydrocracking catalyst

Provided is a hydrodesulfurization catalyst for hydrocarbon oil, the catalyst comprising: an inorganic oxide carrier comprising Si, Ti and Al; and at least one metal component, carried on the inorganic oxide carrier, being selected from the group consisting of group 6 elements, group 8 elements, group 9 elements and group 10 elements, wherein the content of Al in the inorganic oxide carrier is 50% by mass or higher in terms of AlO; the content of Si therein is 1.0 to 10% by mass in terms of SiO; and the content of Ti therein is 12 to 28% by mass in terms of TiO; and in the inorganic oxide carrier, the absorption edge wavelength of an absorption peak from Ti is 364 nm or shorter as measured by ultraviolet spectroscopy.

Hydrodesulfurization catalyst for hydrocarbon oil and method for manufacturing hydrodesulfurization catalyst

A process is provided for improving cold flow properties of distillates, the process comprises the step of contacting a hydrocarbon feedstock with a framework-substituted ultra-stable Y (USY)-type zeolite in which a portion of aluminum atoms constituting a zeolite framework thereof is substituted with zirconium atoms and/or titanium and/or hafnium atoms, thereby producing a dewaxed distillate product.

Modified ultra-stable Y (USY) zeolite catalyst for improving cold flow properties of distillates

The present disclosure relates to a process for the deolefinization of hydrocarbon streams through an aromatic alkylation reaction by olefins, using a catalyst containing a framework-substituted zirconium and/or titanium and/or hafnium-modified ultra-stable Y (USY) type zeolite.

Modified ultra-stable Y (USY) zeolite catalyst for deolefinization of hydrocarbon streams

The invention relates to methods for hydrocracking or hydrotreating hydrocarbon containing feedstocks. This is accomplished via the use of a catalyst which comprises a &#x3b2; zeolite of *BEA framework, where a portion of aluminum atoms in the *BEA framework have been substituted by from 0.1-5.0 wt % of each of Ti and Zr, calculated on an oxide basis.

Hydrocracking catalyst comprising a beta zeolite (*BEA) framework substituted with Ti and Zr and methods for its preparation and use

The present invention provides a hydrodesulfurization catalyst that exhibits a high desulfurization activity when used in hydrotreatment of hydrocarbon oil, in particular straight-run gas oil. The catalyst includes at least one type of metal component selected from Groups VIA and VIII in the periodic table, supported on a silica-titania-alumina support where the total of the diffraction peak area indicating the crystal structure of anatase titania (101) planes and the diffraction peak area indicating the crystal structure of rutile titania (110) planes is &#xbc; or less of the diffraction peak area indicating the aluminum crystal structure ascribed to &#x3b3;-alumina (400) planes, as measured by X-ray diffraction analysis. The catalyst has (a) a specific surface area (SA) of 150 m/g or greater, (b) a total pore volume (PVo) of 0.30 ml/g or greater, (c) an average pore diameter (PD) of 6 to 15 nm (60 to 150 &#x212b;), and (d) the ratio of the pore volume (PVp) of pores having diameters within &#xb1;30 percent of the average pore diameter (PD) being 70 percent or greater of the total pore volume (PVo).

Hydrodesulfurization catalyst for hydrocarbon oil, process of producing same and method for hydrorefining

A hydrodesulfurization catalyst is produced by pre-sulfurizing a hydrodesulfurization catalyst Y including a support containing silica, alumina and titania and at least one metal component supported thereon and selected from VIA and VIII groups of the periodic table (comprising at least Mo), in which the total area of the diffraction peak area indicating the crystal structure of anatase titania (101) planes and the diffraction peak area indicating the crystal structure of rutile titania (110) planes in the support, measured by X-ray diffraction analysis being &#xbc; or less of the alumina diffraction peak area assigned to &#x3b3;-alumina (400) planes. The molybdenum is formed into molybdenum disulfide crystal disposed in layers on the support by the pre-sulfurization, and having an average length of longer than 3.5 nm and 7 nm or shorter in the plane direction and an average number of laminated layers of more than 1.0 and 1.9 or fewer.
