CHARACTERISTICS OF LUBRICATING GREASE PRODUCED FROM NIGERIAN TARSAND-DERIVED HEAVY OIL

The results of a study involving the laboratory production of lubricating grease from heavy oil extracted from the Nigerian tarsands are reported. Toluene-extracted oil from the tarsands was used in making a soap-based grease and a clay-based grease. The grease produced vas then tested in accordance with the standard National Laboratory for Grease Institute (NLGI) specifications. The two types of grease produced from the tarsands oil conformed with the NLGI specifications and were in the category of grease suitable for use as lubricant for plain and roller bearings and as sealants.
