%X Removing metal contaminants in heavy oils can reduce high-temperature corrosivity of the oils during combustion process.Because some heavy metals in heavy oils such as Ni,V exist in porphyrin compounds or oil-soluble compounds,it is very difficult to get rid of them.In this paper,the demetallizing reagent is used by a medium-type test facility to react with the heavy metal,and the metal contaminants are removed by electric-desalting finally.The influence of reaction temperature,reaction time and electric-field strength on the removal rate has also been studied.This technology is one new method to solve the high-temperature corrosion problem,and can be applied for industrial mass production.
