Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
A process for converting a heavy hydrocarbon charge containing asphaltenes and metal, sulfur and nitrogen impurities, in order to obtain products of lower boiling point and lower impurities content, wherein a mixture of said charge with hydrogen is contacted with a catalyst composition comprising at least two essential elements: (a) soot of the cenosphere type, resulting from the combustion of liquid heavy hydrocarbon charges containing at least one metal of the iron, nickel and vanadium group, said metal being also present in said soot, and (b) at least one catalytic metal compound distinct from the element (a) and selected from the compounds of metals of groups VB, VIB, VIIB and VIII.
Claim 2
Dependent Claim
111 words
A process for converting a heavy hydrocarbon charge containing asphaltenes and metal, sulfur and nitrogen impurities, in order to obtain products of lower boiling point and lower impurities content, wherein a mixture of said charge with hydrogen is contacted with a catalyst composition comprising at least two essential elements: (a) soot of the cenosphere type, resulting from the combustion of liquid heavy hydrocarbon charges containing at least one metal of the iron, nickel and vanadium group, said metal being also present in said soot, and (b) at least one catalytic metal compound distinct from the element (a) and selected from the compounds of metals of groups VB, VIB, VIIB and VIII.
Claim 3
Dependent Claim
42 words
A process according to claim 1, wherein element (b) is added to the hydrocarbon charge in the form of a solution in a hydrocarbon solvent, a solution in a non-hydrocarbon solvent or an emulsion of an aqueous solution in a hydrocarbon solvent.
Claim 4
Dependent Claim
48 words
A process according to claim 1, wherein the particles of soot of the cenosphere type have an average diameter of 10 to 200 μm and contain 60 to 90% by weight of carbon and 1 to 10% by weight of metals of the iron, nickel and vanadium group.
Claim 5
Dependent Claim
32 words
A process according to claim 3, wherein the soot of the cenosphere type contains, by weight, 0.1 to 2% of vanadium, 0.1 to 5% of iron and 0.2 to 1% of nickel.
Claim 6
Dependent Claim
51 words
A process according to claim 1, wherein the cenospheres have a specific surface of 1 to 130 m 2 /g, a total pore volume of 0.8 to 2.5 cm 3 /g, a particle density of 0.3 to 0.8 g/cm 3 and a structural density of 1.2 to 2.5 g/cm 3 .
Claim 7
Dependent Claim
51 words
A process according to claim 1, wherein the censopheres have a specific surface of 2 to 20 m 2 /g, a total pore volume of 1.2 to 1.7 cm 3 /g, a particle density of 0.4 to 0.6 g/cm 3 and a structural density of 1.3 to 2.1 g/cm 3 .
Claim 8
Dependent Claim
35 words
A process according to claim 1, wherein the amount of cenospheres is 0.1 to 5% b.w. of the hydrocarbon charge and the amount of element (b) from 10 to 1000 ppm b.w. of said charge.
Claim 9
Dependent Claim
29 words
A process according to claim 1, wherein the hydrocarbon charge, after introduction of the two catalyst elements, is treated with hydrogen sulfide, before being subjected to the conversion process.
Claim 10
Dependent Claim
28 words
A process according to claim 1, wherein the metal of compound (b) is selected from the group consisting of molybdenum, vanadium, chromium, tungsten, manganese, iron, nickel and cobalt.
