20090239743 | CATALYST COMPOSITION, ITS PREPARATION AND USE - An unsupported catalyst composition which comprises one or more Group VIb metals, one or more Group VIII metals, and a refractory oxide material which comprises 50 wt % or more titania, on oxide basis, which is prepared by precipitation techniques, finds use in the hydroprocessing of hydrocarbonaceous feedstocks. | 09-24-2009 |
20110000822 | METHOD FOR THE START-UP OF A CATALYTIC PROCESS - The present invention relates to a process for starting up a hydrotreating process using a bulk metal catalyst, said process comprising the steps of: i) providing a hydrocarbon feed stream containing less than 100 ppmw nitrogen-containing species; ii) adding a nitrogen-containing compound to said hydrocarbon feed stream; and iii) contacting the resultant feed stream with the bulk metal catalyst in the presence of hydrogen and a sulfur-containing species. The present invention also relates to a process for hydrotreating a hydrocarbon feedstock, said process comprising the steps of: i) providing a hydrocarbon feed stream containing less than 100 ppmw nitrogen-containing species; ii) adding a nitrogen-containing compound to said hydrocarbon feed stream; iii) contacting the resultant feed stream with a bulk metal catalyst in the presence of hydrogen and a sulfur-containing species; and iv) subsequently contacting the resultant bulk metal catalyst with the hydrocarbon feedstock in the presence of hydrogen. | 01-06-2011 |

20130153463 | TITANIA-BOUND ZSM-12 ZEOLITE COMPOSITION AND METHOD OF MAKING AND USING SUCH COMPOSITION - Presented is a composition useful in the catalytic dewaxing of a waxy hydrocarbon feedstock. The composition includes a mixture of ZSM-12 zeolite and titania and may further include a noble metal. The ZSM-12 zeolite preferably has a high silica-to-alumina ratio within its framework. The mixture may be dealuminated either by acid leaching using a fluorosilicate salt or by steam treating. | 06-20-2013 |
20130220887 | TITANIA-BOUND ZEOLITE EU-2 COMPOSITION AND METHOD OF MAKING AND USING SUCH COMPOSITION - Catalyst composition useful in the catalytic dewaxing of a waxy hydrocarbon feedstock which catalyst composition includes a mixture of zeolite EU-2 and titania and may further include a noble metal. The zeolite EU-2 has a molar bulk ratio of silica-to-alumina (SAR) of greater than 100:1. The zeolite or mixture may have been dealuminated such as by acid leaching using a fluorosilicate salt or by steam treating. | 08-29-2013 |
20140209506 | HYDROCARBON CONVERSION CATALYST COMPOSITION - A hydrocarbon conversion catalyst composition which comprises dealuminated ZSM-48 and/or EU-2 zeolite and a refractory oxide binder essentially free of alumina, processes for preparing such composition and processes for converting hydrocarbon feedstock with the help of such compositions. | 07-31-2014 |
20150273447 | PROCESS FOR THE PREPARATION OF A HYDROCRACKING CATALYST - This invention relates to a process for the preparation of a hydrocracking catalyst and its use. A zeolite Y having specifically defined properties is mixed with an alumina binder component and a first metals-containing solution that is extruded to form an extruded mixture. The extruded mixture is dried and calcined. The dried and calcined mixture is then impregnated with a second metals-containing solution. | 10-01-2015 |
