Properties of rubber seed oil biodiesel

The lubricity,combustibility,elastomer compatibility,oxidative stability and low-temperature performance of rubber seed oil biodiesel were investigated.The results showed that the lubricity of rubber seed oil biodiesel was better than that of petroleum diesel,and the engine fuelled with biodiesel wore smaller.The cetane number of rubber seed oil biodiesel was high,so its combustibility was good.The rubber seed oil biodiesel had a bad compatibility with the elastomer,so it was necessary to select rubber kinds to meet the operating requirements.The rubber seed oil biodiesel was very susceptible to oxidation,but by adding antioxidants its oxidation stability could be improved significantly and could met the national standard specification well.The cold flow property of rubber seed oil biodiesel was worse than that of petroleum diesel,but when petroleum diesel was mixed with rubber seed oil biodiesel,its cold flow property was limitedly affected.
