Process for the oligomerization of olefins and a catalyst thereof |
| abstract |
An olefinic feedstock containing contaminants such as oxygenates may be oligomerized to a desired oligomer which contains a particular configuration. The process may be effected by utilizing a catalyst which comprises a porous support containing a catalytically effective amount of an iron group metal compound in combination with a catalytically effective amount of an alkyl aluminum compound and an activator comprising an aluminum alkoxide. The presence of the latter compound in the catalyst compound will permit the catalyst to maintain its activity and stability over a relatively long period of time. The catalyst of the invention is prepared by impregnating a porous support with an aqueous solution of an iron group metal salt, calcining and contacting the calcined support with a solution containing an alkyl aluminum compound and an aluminum alkoxy compound. |
