TECHNOLOGICAL DEVELOPMENT OF SOY OIL BIODIESEL ADDED AS FUEL AND ECO-COMPATIBLE LUBRICANT

摘要

In the present invention soybean oil (glycine max l. merrill) biodiesel was obtained in the additive composition b7 (7% biodiesel and 93% diesel s10) in order to obtain biofuel with less wear action on alloy surfaces. . To this end, 5% of a semi-synthetic surfactant (saponified vegetable oil) was used as a protective agent. biofuels b7-os (b100 soybean oil biodiesel) and b7-os-ad additive) were evaluated using a high frequency reciprocating test rig (hfrr). The reduction of friction and wear of the Aisi 52100 steel was evaluated by improving the viscosity and lubricating film formation of additive soybean biodiesel (b7-os-ad). Tribological tests have shown that diesel s10 and biodiesel b7-os are more susceptible to oxidative processes. Additive soybean biodiesel (b7-os-ad) showed better viscosity and stability, with a 32.9% wear reduction of aisi 52100 metal compared to s10 diesel, and a 13.63% smaller wear eschar size. that the wear observed for the mixture b7-os. Therefore, b7-os-ad is being indicated as an alternative to the use of s10 diesel, with a gain in reducing environmental impacts.
