description |
Biodiesel is currently in regular use as an alternative fuel over conventional petroleum
diesel. However, corrosion of automotive materials is one of the concerns related to
biodiesel compatibility issues. The present study aims to investigate the effects of Tertbutylamine
and Benzotriazole additive addition on the corrosion behavior of low carbon
steel S45C material in different biodiesel blends. Static immersion tests in biodiesel
conducted for 1440 hours on solution B0, B20, B50 and B100 without the presence of
corrosion inhibitors. Similar testing was carried out with the addition of additive Tertbutylamine
and Benzotriazole on solution B20 and B100. At the end of the test,
corrosion characteristic was investigated by weight loss measurements, corrosion rate
and changes on the exposed metal surface (EDX). Fuels were analyzed by using TAN
(total acid number) analyzer and Density measurement in order to investigate the acid
concentration and compositional characteristics respectively. Surface morphology was
examined by digital photography and scanning electron microscope (SEM). The test
result indicates that biodiesel is more corrosive to low carbon steel S45C sample when
compared to diesel. The presence of additive Tert-butylamine and Benzotriazole, acts as
corrosion inhibitor that retards the corrosion attack and protects the sample from further
deteriorating. Both additives improve the corrosion behavior of the low carbon steel
S45C sample. However the results indicate that Tert-butylamine acts as the more
efficient and effective corrosion inhibitor for low carbon steel S45C operating in
biodiesel environment. |
