PROCESS OF THE MANUFACTURE OF LUBRICATING-OILS AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 28, 11915.

Application filed July 9, 1914. Serial No. 850,027.

To all whom it may concern:

Be it knownthat I, JEAN RosEN, a citizen of France, residing at 25 Rue Pigalle, Paris, France, have invented certain new and useful Improvements in Processes of Manufacture of Lubricating-Oils and the like, of which the following is a specification.

This invention relates to a process for the manufacture of lubricating oils, cylinder oils and the like, which prevents the decomposition of the raw material at a high temperature during the distillation of this material. The raw material used for the manufacture of said oils, for instance, petroleum residues or petroleum tar (the remainder after kerosene is driven off petroleum) is first distilled in a known manner and carrier air or steam for example is introduced into the raw material, whereupon the carrier is replaced by a product of decomposition 71. 6. solar or cracked oil, the formation of which is to be avoided, said product being preferably supplied in a cold liquid condition.

When distilling petroleum residues or petroleum tar for instance the mean boiling point of which is high, products of decomposition are usually obtained which distil, at about 280 C. and are termed solar or cracked oils (hm'les solaz'res). When the petroleum residues or tars attain during distillation a temperature of about 320 (3., solar oil which distils at 280 is introduced into mass to be distilled is preferably divided for i this purpose into several parts that communicate with each other by suitable partition walls provided in the still and the carrier is introduced into one of these parts.

Reference is now to be had to the accompanying drawing showing a diagrammatic view*of apparatus which may be used in carrying out the process.

I employ a reservoir 1 having two compartments 2 and 3 divided by a partition 4: which permits communication between the compartments both at the top and bottom of the partition. An inlet or supply pipe 5 connects with the bottom of the reservoir below one compartment and an outlet pipe 6 for distillate leads from the top of the reservolr. Cut off valves 7 and 8are provided in the pipes 5 and 6. A heating coil or pipe 9 through which a heating medium like steam passes, may be used to boil the raw material. The petroleum residue or tar (the material remaining after driving off kerosene from petroleum) is introduced into the reservoir 1 through an opening normally closed by a cap 10 and therein heated to a temperature of about 320 C. With valve 7 open,v

solar or cracked oils are supplied through pipe 5 into one of the compartments, for instance 2, at a temperature of about 280. The solar or cracked oil decomposes and serves as a carrier for the distillate from the reservoir, which passes therefrom through the pipe 6. While this action takes place in compartment 2, the residue or tar in compartment 3 is necessarily drawn .into compartment 2 so that the solar or cracked oil cooperates therewith as well as with the material in compartment 2.

What I claim is:

1. The process of distillation consisting in heating the raw material to be distilled, such as petroleum residue, to a temperature of about 320 (1., andthen introducing thereinto a liquid carrier consisting of solar or cracked oil at a temperature lower than the temperature of the material at the moment of introduction to be vaporized by the material and serve as a carrier for the distillate therefrom.

2. The process for the manufacture of lubricating oils, cylinder oils and the like consisting of heating petroleum residue to a temperature of about 320 (1, and then introducing thereinto a liquid carrier at a temperature lower than the material being dis tilled at the moment of introduction, such carrier consisting of the products of decomposition usually obtained When distilling said raw material, said raw material being contained in a plurality of communicating compartments and the carrier liquid being supplied to one of the compartments only to be vapori zed by the petroleum residue and 'In testimony whereof I aflix my signature.

JEAN ROSEN.
