8278241 Amorphous silica-alumina composition and a method of making and using such composition October 2, 2012
Described is a novel amorphous silica-alumina composition having a high ratio of pore volume contained in large pores to pore volume contained in medium to small pores. The amorphous silica-alumina composition also may have the characteristic of a strong aluminum-NMR penta-coordinated pe
8088706 Catalyst composition preparation and use January 3, 2012
A bulk metal oxide catalyst composition of the general formula (X)b(M)c(Z)d(O)e (I) wherein X represents at least one non-noble Group VIII metal; M represents at least one non-noble Group VIb metal; Z represents one or more elements selected from aluminum, silicon, magnesium, tita
7737074 Sulfur tolerant noble metal containing aromatics hydrogenation catalyst and a method of making a June 15, 2010
An aromatics hydrogenation catalyst composition which comprises a noble metal component and a support comprising zirconia, silica, and, optionally, alumina. The catalyst composition is manufactured by co-mulling silica, a zirconium compound, and, optionally, alumina to form a mixture
7641789 Process to prepare a base oil having a viscosity index of between 80 and 140 January 5, 2010
Process to prepare a base oil having a viscosity index of between 80 and 140 starting from a distillate or a de-asphalted oil by (a) contacting the feedstock in the presence of hydrogen with a sulphided hydrodesulphurization catalyst comprising nickel and tungsten on an acid amorphou
7638037 Process for the preparation of a lubricant December 29, 2009
Process to prepare a lubricant having a dynamic viscosity at -35.degree. C. of below 5000 cP by performing the following steps: a) contacting a feed containing more than 50 wt % wax in the presence of hydrogen with a catalyst comprising a Group VIII metal component supported on a ref
7544285 Catalyst composition preparation and use June 9, 2009
A bulk metal oxide catalyst composition of the general formula (X)b(M)c(Z)d(O)e (I) wherein X represents at least one non-noble Group VIII metal; M represents at least one non-noble Group VIb metal; Z represents one or more elements selected from aluminium, silicon, magnesium, titan
7261806 Process to prepare a base oil from slack-wax August 28, 2007
A process to prepare a base oil starting from a slack wax containing feedstock by (a) contacting the feedstock in the presence of hydrogen with a sulphided hydrodesulphurisation catalyst having nickel and tungsten on an acid amorphous silica-alumina carrier and (b) performing a pour
6190538 Process for the preparation of a catalyst composition February 20, 2001
