TITLE SEPARATION OF FINE SOLIDS FROM PETROLEUM OILS AND THE LIKE INVENTOR J. REDMOND FARNAND ABSTRACT OF THE DISCLOSURE Dispersed solids, particularly fine peptized hydrophobic solids, present in some petroleum oils, bitumen solutions or concen- trates, heavy oils and the like, may be removed by distributing an additive selected from resorcinol, catechol, formic acid, maleic acid or anhydride, chloral hydrate and asphaltene - precipitating solvents (preferably certain mixtures thereof) throughout the dispersion to cause small agglomerates containing the solids to form, and separat- ing the agglomerates from the residual liquid. This residual liquid is rendered more suitable for various refining processes. Agglomerates containing asphaltenes and mineral solids may be used e.g. in hydrogen generation, for compounding roofing materials and in paving materials.
