초록 ▼

We provide a graded catalyst system which is used for removing calcium and sodium from hydrocarbon feed having at least 1 ppm calcium and 1 ppm sodium. It comprises two catalyst zones characterized as having decreasing porosity, increasing activity, and increasing surface to volume ratio in the direction of feed flow through the system. We also disclose a process for using it and a method for selecting catalyst for use therein.

대표청구항 ▼

A process for hydrodemetalating a hydrocarbon feedstock having at least 1 ppm oil-soluble calcium and 1 ppm oil-soluble sodium, using a graded catalyst system, said process comprises: passing said feedstock, in the presence of hydrogen, through said system at hydrodemetalating conditions, wherein said system comprises at least two successive catalyst zones characterized as follows: (a) said first zone comprising a fixed bed of catalyst particles having at least 10 volume percent of their pore volume above 1000 Åin diameter, and a surface area ranging from about 50 m2/g to about 200 m2/g, less than 3.5 wt % of a Group VIII metal, and less than 8.0 wt % of a Group VIB metal for removal of metal components from said feedstock including said oil-soluble calcium; and (b) said second zone comprising a fixed bed of catalyst particles having less than 20 volume percent of their pore volume in the form of macropores about 1000 Åin diameter, an average mesopore diameter ranging from about 80 Åto about 400 Åand a surface area ranging from about 80 m2/g to about 300 m2/g, at least 0.7 wt % of a Group VIII metal, and at least 3.0 wt % of a Group vIB metal for further removal of metal components from said feedstock including said oil-soluble sodium.
