摘要:
The invention relates to a catalyst comprising an alumina or silica or silica-alumina support, at least one group VIII element, at least one group VIB element and γ-ketovaleric acid. The invention also relates to the method for preparing said catalyst and the use thereof in a hydroprocessing and/or hydrocracking method.
摘要:
Methods are provided for hydroprocessing a feed (such as hydrotreating, hydrocracking, or hydrofining a feed) to generate a product with a reduced or minimized aromatics content relative to the severity of the hydroprocessing conditions. In some types of hydroprocessing applications, it can be desirable to select the severity of hydroprocessing conditions to achieve a desired level of removal for sulfur, a desired level for removal of nitrogen, and/or a desired level for increasing the viscosity index of a feed. The severity for heteroatom removal and/or viscosity index uplift can also correspond to an amount of conversion of a feed to lower boiling point products, so the lowest severity conditions suitable for achieving a product quality can be desirable. By improving the aromatics saturation during hydroprocessing, the severity of subsequent aromatics saturation processes can be reduced.
摘要:
The invention relates to a process for the preparation of a shaped bulk catalyst comprising metal oxidic particles comprising one or more Group VIII metals and two or more Group VIB metals, which process comprises the steps of providing first metal oxidic particles comprising one or more first Group VIII metals and one or more first Group VIB metals, providing separately prepared second metal oxidic particles comprising one or more second Group VIII metals and one or more second Group VIB metals, wherein the composition of Group VIB and Group VIII metals in the first and second metal oxidic particles are different, combining the first and second metal oxidic particles to form a bulk catalyst composition before and/or during shaping and shaping the combined first and second metal oxide particles to form the shaped bulk catalyst. The invention further relates to the shaped bulk catalyst obtainable with the process in sulfphided or unsulphided form and the use thereof in hydroprocessing.
