Abstract: This paper describes the effect of dithiocarbamate compounds on nickel and vanadium removal from Xinjiang heavy crude oil under microwave condition. A series of dithiocarbamate NS compounds with —CSS— coordination group were synthesized,which can be used to remove nickel and vanadium from crude oil by complexing reaction. In comparison with different NS compounds,the effect on nickel and vanadium removal was evaluated,which follows the order of NS3 >NS2 > NS4 >NS1. Moreover,under microwave condition with 700W power for 3min and reaction temperature of 90℃ for 20min,200mg/L NS3 were reacted with crude oil,and the removal effect of nickel and vanadium from crude oil were 79.8% and 82.4%,respectively. Therefore,the results indicate that microwave condition can facilitate removal effect of nickel and vanadium.

Key words: microwave, heavy crude oil, dithiocarbamate, nickel, vanadium
