Process for removal of residual catalyst components
View Patent ↗A process for reducing the level of residual catalyst comprising one or more alkylhalide, alkoxyhalide, metal halide, metal oxyhalide, alkyl metal, alkoxy metal, boron compound and coordinated metal compound wherein the metal is a Group III, Group IV, Group V, Group VI and/or Group VIII metal, from a crude organic product (e.g., polyolefins, alkylated aromatic compounds, alkylated amines, etc.) comprising the residual catalyst is provided, the process comprising contacting the crude organic product with a solid adsorbent in an adsorbent system.
1. A process for reducing, from a crude organic product, the level of a residual catalyst used to form an organic product, the process comprising
contacting the crude organic product with a treatment consisting of a solid adsorbent,
wherein the solid adsorbent is selected from the group consisting of an oxide or hydroxide of magnesium, calcium, strontium, barium, sodium and potassium, and
wherein the residual catalyst is selected from the group consisting of metal halide, metal oxyhalide, alkyl metal, alkoxy metal, boron compounds and coordinated metal compounds, the metal of the residual catalyst is selected from the group consisting of Group IIIb, Group IVa, Group Va, Group VIa, and Group VIIIa metals; and
filtering the crude organic product to remove the metal of the residual catalyst.
2. The process of claim 1 , wherein the crude organic product is a polymer.
3. The process of claim 1 , wherein the crude organic product is a polyolefin.
4. The process of claim 1 , wherein the crude organic product is a polylalphaolefin.
5. The process of claim 1 , wherein the crude organic product is polydecene.
6. The process of claim 1 , wherein the crude organic product is derived from an alkylation or transalkylation reaction.
7. The process of claim 1 , wherein the crude organic product is an alkylated benzene.
8. The process of claim 1 , wherein the crude organic product is ethyl benzene.
9. The process of claim 1 , wherein the crude organic product is an alkylated diphenylamine.
10. The process of claim 1 , wherein the crude organic product is nonylated diphenylamine.
11. The process of claim 1 , wherein residual catalyst is a metal halide and the halide is selected from the group consisting of chlorine, bromine and mixtures thereof.
12. The process of claim 1 , wherein the halide is chlorine.
13. The process of claim 1 , wherein the halide is bromine.
14. The process of claim 1 , wherein the Group IIIa metal is aluminum.
15. The process of claim 1 , wherein the Group VIIIb metal is iron.
16. The process of claim 1 , wherein the Group IVb-VIb metal is selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten and mixtures thereof.
17. The process of claim 1 , wherein the adsorbent is an oxide or hydroxide of calcium.
18. The process of claim 1 , wherein the adsorbent system is a fixed or fluidized bed.
19. The process of claim 1 , wherein the adsorbent system is contained in a packed column.
20. The process of claim 1 , wherein the adsorbent system is mixed with the crude product and then separated.
21. The process of claim 20 , wherein the adsorbent is removed by filtration.
22. The process of claim 1 , wherein a diluent is added to the crude organic product.
23. The process of claim 1 , wherein a solvent is added to the crude organic product.
24. The process of claim 1 , wherein the crude organic product is polydecene and the process further comprises adding decene to polydecene.
