    摘要： Methods are provided for producing Group II and Group III base stocks with a controlled or consistent aromatics content. An aromatics-rich base stock, such as a Group I base stock or an alkylated aromatic base stock, can be added to the catalytically treated base stock in a minimal amount after the final catalytic treatment step but prior to fractionation. At the beginning of a processing run for forming lubricant base stock products, about 0.25 wt % to about 1.25 wt % of the Group I base stock can be added to a catalytically processed feed after the final catalytic processing stage but prior to fractionation to form the Group II and/or Group III base stock. During the course of the processing run, the amount of Group I base stock added can be reduced roughly in correspondence with the increase in aromatics caused by catalyst deactivation. This can allow a catalytically processed lubricant base stock product to be generated that contains at least about a threshold (minimum) aromatics content during the course of a processing run. Alternatively, this can allow a catalytically processed lubricant base stock product to be generated that has consistent aromatics content during the course of the processing run.

    摘要： A hydrogenation process for reducing the unsaturation of lubricants uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material has pores of at least 13 .ANG. diameter arranged in a uniform manner and exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams (50 torr and 25.degree. C.). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG.. The hydrogenation catalysts based on these materials are capable of reducing the unsaturation in poly alpha olefin lubricants to a low level.

    摘要： The behavior of a monitored condition over time for a reactor or reaction system can be analyzed using groupings or windows of data to identify anomalous features in the time-average values. Anomalous features can be identified based on a threshold value generated from the analysis. Based on identification of an anomalous feature, a corrective action can be taken. For example, when the monitored condition is the pressure drop across a catalyst bed, detection of an anomaly can indicate the time to initiate a wash process for the catalyst bed before a large drop in catalyst activity occurs. By detecting an anomaly at an earlier point in time, a wash cycle can be initiated earlier so that the wash is more effective at restoring the catalyst bed to a desired condition.
