摘要： In a process for producing an essentially ash-free oil stock from a lubricating oil containing ash forming components comprising reacting the oil with an aqueous ammonium salt capable of reacting with the ash-containing components and heating the thus treated oil at a temperature in the range of about 300.degree. C. to about 420.degree. C. to increase the amount of the ash-forming components removed, the improvement comprising not exposing the oil to a temperature greater than 200.degree. C. before the oil is passed into a large volume of the oil already at a temperature in the range of about 300.degree. C. to about 400.degree. C.

摘要： A hydrogen donor solvent selected from the group consisting of a full range crude oil and an atmospheric topped crude oil is used in a hydrovisbreaking process. The heavy fraction being processed is heated in the presence of hydrogen and the solvent under suitable hydrovisbreaking conditions. As a result, the amount of heavies in the feed to the hydrovisbreaking process is substantially reduced.
