Abstract: The technological conditions of lubricant synthesizing devices (five sets of coordinated equipment) of Fushun Chemical Plant was investigated in order to increase 8B aviation jet lubricant yield. The practical production and experiment indicate that the primary factors influence the yield and quality of 8B aviation jet lubricant are: composition of α-alkene, temperature of polymerization reaction, time of polymerization reaction, proportion of activator and operation of fractionating device.In the process of production and experiment, high quality paraffin is used to optimize the technological conditions of paraffin decomposition device in order to acquire higher quality α-alkene. Meanwhile, mass fraction of 8B aviation jet lubricant base oil can be boosted from 12%~15% increase to 17%~19% in normal decompressing fractionation through the optimization of technological conditions for subsequent polymerizing device and normal decompressor. It can greatly increase comprehensive economic profit of the device. This means that 4800 tons of paraffin material can be saved in producing every thousand tons of 8B aviation jet lubricant, and corresponding it has obvious economic benefits.
