    摘要: A method for regenerating a spent porous crystalline catalyst, optionally associated with a metal component such as noble and/or base metal(s), is described. The method comprises contacting the spent catalyst which has become deactivated by accumulation of carbonaceous residue with one or more light aromatic compounds under conditions resulting in reactivation of said catalyst. The light aromatic compounds employed are ones which have the capability of penetrating the catalyst, so as to contact the carbonaceous residue contained therein, undergoing alkylation by alkyl fragments contributed by components of the carbonaceous residue and diffusing from or otherwise escaping the catalyst.

    摘要: A method for treating a porous crystalline catalyst optionally associated with a metal component such as a noble and/or base metal(s) is described. The method comprises contacting the catalyst with a low molecular weight aromatic compound under coking conditions. Such a treatment method increases the cycle length and the useful life of the catalyst. Using the treated catalyst in a dewaxing process and regenerating the catalyst by treating with hydrogen and a low molecular weight hydrocarbon.

    摘要: This invention provides a method for extending the catalytic dewaxing cycle time of a refined waxy lube stock. The method, in its broadest aspect, requires the additional refining step of thermally treating the refined waxy stock or precursor thereof for about 0.1 to about 2.0 hours at elevated temperature and at a pressure of 0 to 3000 psig (pounds per square inch gauge), and recovering an upgraded waxy stock having a reduced content of trace compounds that contain metals, nitrogen, sulfur and oxygen.In a specific embodiment of this invention, a vacuum residuum is thermally treated at a temperature of about 700.degree. F. to 950.degree. F. prior to solvent deasphalting and solvent extraction, and the waxy bright stock so formed is catalytically dewaxed with extended cycle time.
