摘要:
A used acidic ionic liquid catalyst, which has been deactivated by conjunct polymers, is regenerated by combining the used catalyst, a metal and a Broensted acid to hydrogenate the conjunct polymer. Regenerating a used acidic ionic liquid catalyst, which has been deactivated by conjunct polymers, includes: combining the used ionic liquid catalyst, a metal and HCI in a reaction zone under hydrogenation conditions to hydrogenate a portion of the conjunct polymer; removing reaction product from the reaction zone; mixing the removed reaction product with a hydrocarbon solvent in which the hydrogenated conjunct polymers are soluble; allowing the mixture to separate into a lighter phase which contains the hydrogenated conjunct polymers, and a heavier phase which contains a regenerated ionic liquid catalyst; and recovering at least a portion of the heavier phase is also disclosed.

A process for regenerating a used acidic catalyst which has been deactivated by conjunct polymers by removing the conjunct polymers so as to increase the activity of the catalyst is disclosed. Methods for removing the conjunct polymers include hydrogenation, addition of a basic reagent and alkylation. The methods are applicable to all acidic catalysts and are described with reference to certain ionic liquid catalysts.

A process for producing a high RON naphtha which comprises contacting a hydrocarbon feed stream comprising a mixture of the isomers of C5 and C6 paraffins with ATS zeolite, such as SSZ-55, in an adsorption zone, whereby the branched isomers of the C5 and C6 paraffins are preferentially adsorbed by the ATS zeolite as compared to the straight chain isomers, and recovering a naphtha product from the adsorption zone having a higher RON than the hydrocarbon feed stream, also including a hydroisomerization process and a hydrocracking process.

The invention provides for a process for dewaxing a waxy hydrocarbon feedstock to form a lubricant oil. The invention is also directed to a catalyst system comprising a hydrotreating catalyst upstream of a dewaxing catalyst, used in the dewaxing of a waxy hydrocarbon feedstock to form a lubricant oil. In particular, the invention is directed to a process and catalyst system designed to maintain yield of lubricant oil product. Specifically, the yield of lubricant oil does not decrease more than 2%, at a target pour point, over a dewaxing temperature range. The hydrotreating catalyst helps prevent aging of the dewaxing catalyst and maintains lubricant oil product yield at a target pour point over a wide temperature range. The hydrotreating catalyst comprises platinum, palladium, or combinations thereof on a low acidity inorganic oxide support where acidity is measured by a decalin conversion of less than 10% at 700F.
