    摘要： A novel, high porosity, high surface area catalyst is disclosed which is useful in wax isomerization processes, especially for the production of high viscosity index, low pour point lubricating oil base stocks or blending stocks. The catalyst contains a catalytically active metal component selected from the group consisting of Group VIB and Group VIII metals, and mixtures thereof, preferably Group VIII metals, and mixtures thereof, more preferably noble Group VIII metals and mixtures thereof, most preferably platinum which catalytically active metal component is present in the range of about 0.01 to 5.0 wt %, and a fluorine content in the range of about 0.01 to about 10.0. The catalyst employs a refractory metal oxide support material, one preferably predominantly (i.e., at least 50 wt %) alumina, most preferably completely alumina, e.g., gamma or eta alumina. The finished catalyst has a porosity, expressed in terms of pore volume, of at least about 0.50 cc/gram and a surface area such that when the porosity is multiplied by the surface area the product obtained is at least about 107, preferably at least about 110, more preferably at least about 115, most preferably at least about 120.

    摘要： Waxy distillates, or raffinates containing from as little as 10% wax but more typically about 30% wax or more are upgraded by a process comprising the steps of hydrotreating the waxy oil under conditions which convert less than 20% of the feed into products boiling lower than the feed to reduce the sulfur and nitrogen content of the oil followed by hydroisomerizing the hydrotreated waxy oil to reduce the wax content and increase the viscosity index. This oil having a waxy content of less than 30%, preferably less than 25%, can now be more easily dewaxed using conventional solvent dewaxing procedures. The advantage of the present process resides in the increased yield and/or stability of oil as compared to other upgrading, dewaxing processes which convert wax to light products. The isomerization catalyst is preferably a low fluorine content catalyst, more preferably a noble metal on 0.1 to less than 2 wt % fluorine on alumina catalyst, most preferably a noble Group VIII metal (e.g. Pt or Pd) on low fluorine content (less than 2 wt % fluorine) on small particle size alumina (less than 1/16 inch diameter) catalyst. The most preferred alumina support is a 1/20 inch trilobe.

    摘要： A wax isomerization catalyst is described which comprises a Group VIII hydrogenation metal component on fluorided alumina or material containing alumina which catalyst possesses a surface nitrogen content N/Al ratio of about 0.01 or less determined by X-ray photoelectron spectroscopy, a bulk fluorine content of between about 2 to 10 wt %, a surface fluorine content defined as the amount of fluorine in a layer extending from the outer surface to a depth of about 1/100 of an inch of less than about 3 wt % provided that the surface fluoride concentration is less than the bulk fluoride concentration and an aluminum fluoride hydroxide hydrate peak height of 60 or less determined as the relative amount of hydrate represented by a peak in the X-ray diffraction pattern at 2.theta.=5.66 .ANG. when a hydrate level of 100 corresponds to the XRD peak height exhibited by a standard material. Also described is a method for producing a slack wax isomerization catalyst said method comprising depositing a Group VIII hydrogenation metal on alumina or material containing alumina extrudate, calcining said metal loaded extrudate, fluoriding said material using an aqueous fluorine source solution having a pH of 3.5 to 4.5 to a bulk fluorine level of about 8 wt % or less followed by heating in an air oxygen containing atmosphere or inert gas from ambient to 350.degree. to 450.degree. C. within 3 hours and holding at the final temperature, if necessary, for a time sufficient to reduce the hydrate and nitrogen contents to the aforesaid levels. Alternatively the catalyst can be made using a fluorine solution of pH less than 3.5 to a bulk fluorine level of about 10 wt % or less followed by heating in air or an oxygen containing atmosphere, or inert atmosphere at about 350.degree. to 450.degree. C.
