Patent GB-712399-A (GB)
Title: Process for manufacturing bituminous materials from acid sludge
IPC: C10C3/02
Filed: 1951-01-26
Abstract: Sulphur dioxide and a fusible bituminous material are simultaneously formed by mixing and heating acid sludge with a reducing material at a temperature above 150 DEG  C. and below the coking temperature, e.g. up to 300 DEG  C. and preferably 200 DEG -250 DEG C. The reducing material employed is a mixture of a non-paraffin hydrocarbon or bituminous material originating from the mineral oil industry selected from solvent extraction residues, distillation residues or unsaturated hydrocarbons produced by cracking or the Fuller's earth bleaching process, and as a second component, a resin, originating from wood, selected from resins or resinous oils, resin distillation residues or modified resins, for example made from rosin and methylolphenolic or methylolketonic intermediates.  The acid sludge may be diluted with any organic solvent and may be worked free of unbound sulphuric acid before being employed in the process.  In an example, rosin and dimethylol acetone (made from acetone and formaldehyde) are heated to 230 DEG  C. in the presence of hydrated lime.  The resultant resin is mixed with a non-paraffin petrol residue and acid sludge added. The mixture is heated to 300 DEG  C. until the sulphur dioxide evolution ceases.  The bituminous material produced may be further treated by distillation or oxidation, whilst the sulphur dioxide may be used in the production of sulphuric acid.ALSO:Sulphur dioxide and a fusible bituminous material are simultaneously formed by mixing and heating acid sludge with a reducing material at a temperature above 150 DEG C. and below the coking temperature.  The reducing material employed is a mixture of a non-paraffinic hydrocarbon or bituminous material originating from the mineral oil industry and a resin, originating from wood.
