Title: Process for the heat treatment of destructive hydrogenation residues
IPC: C10G1/00
Filed: 1936-03-03
Abstract: Oil constituents are recovered from the residues obtained in the destructive hydrogenation of carbonaceous materials by heating the residues in contact with hot molten metals or alloys. A residue comprising 68 per cent oil and 32 per cent solids is heated with steam in a gas-heated preheater to 500 DEG  C. and then passed into a lead bath maintained at 510 DEG  C.  Steam and oil vapours pass off at the top of the vessel while a coke residue collects on the surface of the lead and is drawn off through drain pipes into a second vessel from which any molten material carried off can be returned. Specifications 288,148, [Class 32], and 396,054 are referred to.
