摘要： The present invention discloses a process for producing a low haze heavy base oil including the steps of: (a) providing a heavy waxy feed stream having an initial boiling point greater than 900° F. and having a paraffin content of at least 80%; (b) separating the heavy feed stream into a heavy fraction and a light fraction by a deep cut distillation; and (c) hydroisomerizing the light fraction to produce a low haze heavy base oil.

摘要： A wax blending process is disclosed which retains the desirable properties of a Fischer-Tropsch wax, while adjusting the hardness of the wax to within to a desired range. The invention utilizes a synergistic effect between hard virgin Fischer-Tropsch wax and softer mildly isomerized Fischer-Tropsch wax in a blending process which allows the artisan to adjust the hardness of a wax product to within desired ranges. The process involves passing a Fischer-Tropsch wax over a hydroisomerization catalyst under predetermined conditions including relatively mild temperatures such that chemical conversions (e.g., hydrogenation and mild isomerization) take place while less than 10% boiling point conversion (hydrocracking) occurs, thus preserving overall isomerized wax yield. At least a portion of the resulting isomerized wax is then blended with untreated hard virgin

摘要： An integrated process for preparing a lubricating oil base stock includes an isomerization step followed by a solvent dewaxing step. A waxy feed is isomerized to an intermediate pore point, which is at least 6° C. above a target pour point, over a select molecular sieve having specified pore properties. The isomerized oil is then solvent dewaxed to a very low pour point. This process produces a dewaxed lubricating oil base stock which has an exceptionally high viscosity index.

摘要： A process for isomerization dewaxing of a hydrocarbon feed which includes contacting the hydrocarbon feed with a large pore size, small crystal size, crystalline molecular sieve and an intermediate pore size, small crystal size, crystalline molecular sieve to produce a dewaxed product with a reduced pour point and a reduced cloud point. In a preferred embodiment, the feed is contacted with the molecular sieves sequentially, first with the large pore sieve followed by the intermediate pore sieve.

摘要： A method of refining a petroleum product to remove aromatics and to separate paraffinic oils and waxes is provided. The method involves the utilization of phase equilibria wherein crystallized or solidified waxes, normally present in the petroleum product, are used to remove oils from a liquid solvent phase containing dissolved aromatics present in the unrefined petroleum product. The wax containing the oils is separated from the aromatic-containing solvent and is further processed to separate the waxes and oils. For petroleum products containing little, if any, wax, additional wax may be added and recycled back for further use in removing oils from the petroleum product. The method has particular application in preparing lubricating oils having a high viscosity index, where the presence of aromatics and wax can be detrimental.
