| 20080312074 | Hydrotreating catalyst sulphiding agent and its use for in situ and ex situ presulphidation - The present invention relates to a sulphiding agent for a hydrotreating catalyst which makes possible faster sulphiding of the catalyst but which also makes possible to very significantly limit solid deposits, in particular of sulphur. | 12-18-2008 |
| 20090054226 | Hydroprocessing Bulk Catalyst and Uses Thereof - An improved hydroprocessing catalyst having improved morphology/dispersion characteristics is provided. The hydroprocessing catalyst has the formula (M | 02-26-2009 |
| 20090111686 | Hydroconversion Processes Employing Multi-Metallic Catalysts and Method for Making Thereof - A catalyst precursor composition and methods for making such catalyst precursor are disclosed. The catalyst precursor comprises at least a metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, at least one Group VIB metal, at least one organic, oxygen-containing ligand, and a cellulose-containing material. Catalysts prepared from the sulfidation of such catalyst precursors are used in the hydroprocessing of hydrocarbon feeds. In one embodiment, the sulfidation is carried out by contacting the catalyst precursor with hydrogen and a sulfur containing compound in a “slow” process with the sulfidation taking place over a few days up to two weeks, e.g., for at least over 96 hours. In another embodiment, the sulfidation is in a “quick” process with the sulfidation taking place in less than 72 hours. The catalyst prepared from the slow sulfidation process gives a 700° F.+ conversion rate of at least 25% higher than the 700° F.+ conversion rate of a catalyst prepared from a quick sulfidation process. | 04-30-2009 |
| 20100279853 | Hydroconversion Multi-Metallic Catalyst and Method for Making Thereof - A method for preparing a bulk multi-metallic suitable for hydrotreating heavy oil feeds is provided. In the process of preparing the catalyst precursor which is subsequently sulfided to form the bulk catalyst, a catalyst precursor filter cake is treated with at least a chelating agent, resulting in a catalyst precursor with optimum porosity with at least 90% of the pores being macropores, and having a total pore volume of at least 0.12 g/cc. | 11-04-2010 |
| 20110092360 | PROCESS FOR SULFURIZING HYDROCARBON TREATMENT CATALYSTS - The present invention relates to a process for sulfurizing a hydrocarbon treatment catalyst, comprising:
| 04-21-2011 |
| 20130288886 | IONIC FLUIDS - A method for preparing an ionic compound by mixing at least one compound of formula C | 10-31-2013 |
| 20140057778 | SULFONATED CARBON SILICA COMPOSITE MATERIAL AND A PROCESS FOR THE PREPARATION THEREOF - The present invention relates to a novel sulfonated carbon silica (SCS) composite material and a process for the preparation thereof. The synthesized SCS composite material on calcination yields the hierarchical mesoporous silica (MS) and further finds application as catalyst in two industrially important reactions namely phenol butylation and glycerol acetalization. | 02-27-2014 |
| 20140066291 | MATERIALS AND METHODS FOR IMPROVING SELECTIVITY IN HETEROGENEOUS CATALYSTS AND PRODUCTS THEREOF - Methods for improving selectivity in heterogeneous catalysts, and products thereof, are disclosed. In exemplary embodiments, multifunctional oxygenates may be selectively converted to value-added products through reaction at a single functional position. Addition of a self-assembled monolayer (SAM), or SAM-like structures to a supported metal catalyst is also disclosed. | 03-06-2014 |
