      Heavy oils containing sulfur and at least 80 parts per million metals are simultaneously demetallized and desulfurized by contacting the oil under hydrogenation conditions with a catalyst composition comprising a Group VI-B metal and at least one Group VIII metal composited with alumina, said catalyst composition having an average pore diameter greater than A units, from . The HFC process has been developed to convert vacuum residua over spent HDS catalysts to a synthetic crude oil that can be recycled to the crude-topping unit. The process has been tested for more than hr at a bbl/day pilot plant at kg/sq cm .

    Unity Hydrotreating catalyst has been developed Unity Hydrotreating Catalysts Demetallization Removing metals from a hydrotreating unit’s VGO, heavy coker gas oils, DAO, and more • Achieves longer operating cycles and improves sulfur and nitrogen reduction in.   A composite of 1% manganese on a large pore bauxite (more than 60% of pore volume in pores of greater than A diameter) has also been used for demetallization (Demetallization of Heavy Residual Oils by Rovesti & Wolk, U.S. Environmental Protection Agency, Washington, D. C. , EPA/ published by U.S. Department of Commerce).

The average demetallization achieved was 72% vanadium removal andthe average desulfurization during the demetallization test was34% sulfur removal producing a product oil containing W %sulfur and 63 ppm vanadium.

The feed and product analyses usedin the above calculations were supplied by the USSR Demetallization catalyst tests on heavy residual oils Author: V V Manshilin ; Industrial Environmental Research Laboratory (Research Triangle Park, N.C.) ; Vsesoi︠u︡znyĭ nauchno-issledovatelʹskiĭ institut neftekhimicheskoĭ promyshlennosti.

The same weight of catalyst was used in all tests. Heavy oil is hydrodesulfurized and demetallized by treatment in a first stage with hydrogen in the presence of a catalyst with fine pores, and in a second stage in the presence of a catalyst with larger pores and a specified pore size by:   The purpose of the work is demetallization and desulfurization of heavy oil residues using adsorbents.

At the same time, the Demetallization catalyst tests on heavy residual oils book of inactive demetal1ization agents to accom- plish the demetal1izatlon requires that the residence time in these large reactors be lengthy. This results in unwanted con- sumption of hydrogen which is associated with the cracking of these residual oils, which does not of itself contribute to de- sul furizat ion.

SUPPLEMENTARY NOTES RACT The report gives Phase n results of a study of demetallization of heavy residual oils. Phase I was an experimental laboratory investigation to find a new low- cost demetallization catalyst for high metals, high sulfur residual oils.

It has been found that a combination of a pretreating catalyst with a desulfurization catalyst enables us to operate an HDS unit continuously for one year using a heavy oil containing 50% vacuum residual oil.

heavy crude oils were treated with a variety of chemical agents, and then washed with aqueous solutions to remove the metal. The most effective reagents were found to be maleic acid in.

This paper presents the performance tests for various reactions on two types of industrial hydrotreating catalysts: those used at the midsection and the tail-end of a graded catalyst system designed to hydrotreat atmospheric residual oils.

Heavy oils containing metalloporphyrins principally of nickel and vanadium are demetallized using an oxidizing agent such as aqueous hydrogen peroxide and catalytic amounts of phosphoric acid, preferably with tungstic acid in combination with a phase transfer agent.

Up to 99% of the Ni and V are deposited in the aqueous phase and are removed from the oil. EXPERIMENTAL The demetallization process on heavy vacuum fraction from Soviet petro- leum (HVF) was investigated. This fraction is used as a component of fuel oils.

The properties of the feedstock used are given in Table 1. Demetallization The demetallization process was carried out in a flow reactor with fixed bed of a catalyst of cm3. Metals in petroleum fractions have a deleterious effect on the refining equipment and catalyst.

They corrode the equipment, plug the catalyst pores, and create irregularities in the system. With reference to today’s petroleum industry, the fast depletion of light crude has created the need to process heavier crudes with much higher metal content. Hence, the need to remove traces of harmful.
