    摘要: The invention provides a process for hydrotreating and dewaxing a hydrocarbon feedstock, comprising the steps of: (a) hydrotreating the feedstock under hydrotreating conditions in a first reaction zone to obtain a first stage hydrotreated effluent; and (b) introducing at least part of the first stage hydrotreated effluent into a second reaction zone in which the first stage hydrotreated effluent is subjected to a series of alternating dewaxing steps and hydrotreating steps, which dewaxing steps are carried out under catalytically dewaxing conditions and the hydrotreating steps are carried out under hydrotreating conditions, wherein the first step in the series of alternating dewaxing and hydrotreating steps is a dewaxing step and the last step of the series of alternating dewaxing and hydrotreating steps is a hydrotreating step, and the dewaxing steps are carried out with a dewaxing catalyst which comprises a Group VIII metal hydrogenation component, dealuminated aluminosilicate zeolite crystallites and a low acidity refractory oxide binder material which is essentially free of alumina.

    摘要: A process for upgrading residuum hydrocarbons and decreasing tendency of the resulting products toward asphaltenic sediment formation in downstream processes is disclosed. The process may include: contacting a residuum hydrocarbon fraction and hydrogen with a hydroconversion catalyst in a hydrocracking reaction zone to convert at least a portion of the residuum hydrocarbon fraction to lighter hydrocarbons; recovering an effluent from the hydrocracking reaction zone; contacting hydrogen and at least a portion of the effluent with a resid hydrotreating catalyst; and separating the effluent to recover two or more hydrocarbon fractions.
