A FEASIBILITY STUDY OF THE ENERGY-SAVING APPROACH OF A 3.2 Mt/a HYDROTREATING UNIT

The oxidation stability of rubber seed oil (RSO) biodiesel was investigated by using SH/T0690, SH/T0175 and EN14112 test methods to observe the changes in peroxide value (PV), kinematic viscosity (KV), acid value (AV), iodine value (IV), insolubles and induction period. Results show that PV, KV, AV and insolubles of the RSO biodiesel increase, IV decreases during oxidation tests. The iso-octane insolubles are much higher than the total insolubles, which indicate that great attention should be paid when mixing RSO biodiesel with mineral diesel fuel. The oxidation stability of RSO biodiesel is poor, its induction period can not meet the requirement of National Standard for biodiesel, yet it could be improved by adding antioxidants significantly. With antioxidants the induction period of RSO biodiesel could well meet the requirement of National Standard. The tested five antioxidants all exhibit good effectiveness, and BS100 is the best.
