| titleOfInvention | Process for the reconditioning of used lubricating oils |
| abstract | 537,082. Purifying used lubricating oils. CELEC CORPORATION, Ltd., PHILLIPS, S. M., and BAKER, A. Dec. 11, 1939, No. 31932. [Class 91] Used lubricating oil is reconditioned by adding a colloid dispersion or jelly obtained by boiling or soaking plants, especially those having fleshy leaves such as sisal, p'hormium tenax or aloe in alkaline solutions and then adding acid to the mixture of oil and colloid, which causes flocculation of the colloid ; on filtration the oil is left clear and free from water. Alternatively waste liquor from the boiling of esparto grass may be used as the colloid. Instead of using acid to effect the flocculation a copper or nickel salt solution may be employed, which increases the viscosity of the oil as well as effecting purification. |
