TRIBOLOGICAL PERFORMANCE OF REFINED, BLEACHED AND DEODORISED PALM OLEIN BLENDS BIO-LUBRICANTS

Author(s): MOHAMMED HASSAN*; FARID NASIR ANI** and S SYAHRULLAIL**

Veg­etable oils have been inves­ti­gated to replace petro­leum lubri­cants due to their environmental-friendly char­ac­ter­is­tics and have become a vital source of bio-lubricants. In the inves­ti­ga­tion of the tri­bo­log­i­cal char­ac­ter­is­tics of palm oil as the veg­etable oil, using in its neat form or as par­tial bio-lubricants, a rec­i­p­ro­cat­ing machine was employed. Ini­tially, refined, bleached and deodorised (RBD) palm olein with min­eral oil blends were opti­mised using the design of exper­i­ments pro­ce­dure from the out­comes of the four ball tri­bo­tester. The opti­mised blend was found to have char­ac­ter­is­tics that were bet­ter or at par with min­eral oil. Then, a rec­i­p­ro­cat­ing machine was used for ver­i­fy­ing the blend. In the inves­ti­ga­tion of the opti­mised blend, the sam­ple was tested for a total of 60 hr in inter­mit­tent oper­a­tion. Other than hav­ing sim­i­lar vis­cos­ity for the ISO require­ments, the opti­mised blend demon­strates decreased in the val­ues of mate­r­ial weight loss and cylin­der tem­per­a­tures as com­pared with min­eral oil. Finally, it is con­cluded that the RBD palm olein blend (E53.11/RB46.89) could be a poten­tial par­tial bio-lubricant due to hav­ing no neg­a­tive impact on wear and decent per­for­mance as a bio-lubricator.
