Abstract

Abstract

The characteristics of high temperature rapid pyrolysis of oil slurry were studied by using a rapid pyrolysis device of high-frequency furnace. The effects of pyrolysis temperature and nitrogen flow rate on the compositions and yields of gas and solid phase products were investigated. The results show that the temperature is the key factor to affect the yields of gas phase products. The gas phase products are mainly methane, hydrogen and ethylene. Higher temperature can increase the yields of hydrogen and methane, while the yield of ethylene is affected by the secondary reaction at high temperature and decreased gradually after reaching the maximum at 800℃. The yields of ethane and propylene are lower, and gradually decrease after reaching the maximum at 700℃ due to the secondary reaction. A small amount of acetylene is formed when the temperature is higher than 800℃ and the yield of acetylene will be increased by increasing the temperature. Meanwhile, increasing the nitrogen flow rate can reduce the partial pressure of methane and hydrogen and shorten the residence time of ethylene and propylene in the high temperature area, leading to an increase in the yield of gas phase products. The yield of carbon deposition increases rapidly with the increase of temperature, while the increase of nitrogen flow rate could weaken the secondary reaction and reduce the yield of carbon deposition.
