Abstract

Fluid catalytic cracking (FCC) processes are described, the processes utilizing one or more boron oxide components. Also described are FCC compositions and methods of manufacture. One or more boron oxide components on FCC compatible inorganic particles are added to a FCC unit to crack hydrocarbon feeds, resulting in lower hydrogen and coke yields.

First claim

The invention claimed is:

1. A method of cracking a hydrocarbon feed under fluid catalytic
cracking (FCC) conditions, the method comprising
adding one or more boron oxide components on FCC-compatible inorganic particles to cracking particles in a FCC unit;
wherein:
the FCC-compatible inorganic particles are a first particle type placed in the FCC unit with a second particle type having a composition different than the first particle type;
the first particle type comprises the one or more boron oxide components and a first matrix component;
the second particle type has a composition different from the first particle type, includes a second matrix component and is active for hydrocarbon cracking; and
the first particle type and second particle type are mixed together.

2. The method of claim 1 , wherein the one or more boron oxide components trap a metal in the FCC unit.

3. The method of claim 2 , wherein the one or more boron oxide components form a complex with the metal.

4. The method of claim 3 , wherein the metal is nickel.

5. The method of claim 1 , wherein the one or more boron oxide components are on the cracking particles.

6. The method of claim 1 , wherein the first matrix component and second matrix component comprise non-zeolitic material.

7. The method of claim 6 , further comprising additional particle types, different in composition from the first particle type and the second particle type.

8. The method of claim 1 wherein the one or more boron oxide components are present in an amount in the range of 0.005% to 20% by weight of the FCC-compatible inorganic particles.

9. The method of claim 8 , wherein the cracking particles are present in a range of 60-99% by weight and the FCC compatible inorganic particles are present in a range of 1-40% by weight.

10. The method of claim 1 , wherein the one or more boron oxide components are mobile under the fluid catalytic cracking conditions.

11. The method of claim 1 , wherein the first matrix component and second matrix component are selected from the group consisting of kaolinite, halloysite, montmorillonite, bentonite, attapulgite, kaolin, amorphous kaolin, metakaolin, mullite, spinel, hydrous kaolin, clay, gibbsite (alumina trihydrate), boehmite, titania, alumina, silica, silica-alumina, silica-magnesia, magnesia and sepiolite.

12. The method of claim 1 , where the first matrix component and second matrix component comprise an aluminosilicate material.

13. The method of claim 1 , wherein the cracking particle comprises a molecular sieve component intergrown with matrix material.

14. The method of claim 1 , wherein the cracking particle comprises a molecular sieve mixed with matrix material.
