    摘要: A three stage process for producing high quality white oils, particularly food grade mineral oils from mineral oil distillates. The first reaction stage preferably employs a sulfur resistant hydrotreating catalyst and produces a product suitable for use as a high quality lubricating oil base stock. The second reaction stage preferably employs a hydrogenation/hydrodesulfurization catalyst combined with a sulfur sorbent and produces a product stream which is low in aromatics and which has substantially “nil” sulfur. The final reaction stage employs a selective hydrogenation catalyst that produces a product suitable as a food grade white oil.
