limited States Patent REMOVAL OF VANADIUM AND/0R SODIUM FROM PETROLEUM AND PETROLEUM PIODUCTS WITH ALUMINA AND IRON 0 IDE Frederick William Bertram Porter and Roy Purdy Northcott, Sunbury-on-Thames, England, assignors to The British Petroleum Company Limited, a British jointstock corporation No Drawing. Application June 16, 1953, Serial No. 362,144

In co-pending U. S. application Serial No. 263,956, filed December 28, 1951, there is described a process in which vanadium and/or sodium are/is removed from petroleum or petroleum products by contact with bauxite in the presence or absence of hydrogen and under conditions of temperature and pressure such that the vanadium and/or sodium are/is deposited on or incorporated with the baumte. It was later discovered that the degree of vanadium and/ or sodium removal under any given set of operating conditions tended to vary with bauxites of difierent origins.

It has now been found that vanadium and/or sodium in petroleum or petroleum products can be removed by treatment with iron oxide on alumina.

According to the invention therefore, a process for removing vanadium and/ or sodium from crude petroleum or a petroleum product comprises contacting the crude petroleum or petroleum product with a contact material consisting essentially of iron oxide and alumina, in the presence of hydrogen and under conditions of temperature and pressure such that vanadium and/or sodium are/ is deposited on the contact material.

The contact material preferably contains from 515% by weight of ferric oxide the remainder consisting essentially of alumina.

The preferred ranges of operating conditions for the process are as follows:

Space velocity 0.5 to 2.0 v./v./hr. Temperature 750 to 800 F.

Pressure 500 to 1500 p. s. i. g. a. Hydrogen recycle rate 1000 to 10,000 S. C. F./B.

The process of the invention is particularly adaptable as a pre-treatment process for crude petroleum or petroleum products which are to be passed to a catalytic hydrogenation process for the removal of organically combined sulphur. For example, it has been found that in the hydrofining of crude petroleum and petroleum residues using a catalyst consisting of cobalt and molybdenum oxides supported on alumina, substantial proportions of vanadium and sodium are removed by and deposited on the catalyst and this deposition causes a steady decline in catalyst activity with hours on stream which is not wholly recovered on regeneration in the conventional manner. This invention, therefore, also includes a continuous process wherein a petroleum feedstock containing vanadium and/or sodium is first treated with iron oxide on alumina, as above described, and is then passed to a hydrogenation zone for the removal of organically combined sulphur.

An example of the application of the invention to the treatment of a petroleum residue will now be given.

EXAMPLE Sodium and vanadium removal from Kuwait 53% volume residue.

Conditions employed Feedstock Kuwait 53% vol. residue. Space velocity 1.0 v./v./hr. Temperature. 780 F. Pressure 1000 p. s. i. g. a. Hydrogen recycle rate 4000 S. C. F./B. Direction of flow Upward. Duration of test 50 hours.

Results obtained IRON OXIDE 0N ALUMINA [12.8% wt. ezOa] Product Feedstock (bulk over 50 hrs.)

We claim: A process for removing vanadium and sodium from a crude petroleum feedstock comprising contacting the petroleum feedstock with a contact material consisting essentially of alumina to which has been added 5-15 by weight of ferric oxide in the presence of hydrogen and at a temperature within the range of about 750800 F. and a pressure within the range of about 500-1500 p. s. i. g. a. such that vanadium and sodium are deposited on the contact material.
