Effect of FeSO<sub>4</sub> on the Reactivity of Petroleum Coke with CO<sub>2</sub> by TG-FTIR

Abstract

The petroleum coke (refered to as PC) with the addition of FeSO4 was obtained by impregnation method, and the reactivity of PC with CO2 are analysed by TG.PC samples were heated from room temperature to 1300 °C with heating rate of 20 °C / min at the atmosphere of CO2 (40 ml/min) and N2 (60 ml/min).At the same time, FTIR spectral of the gasflowing was obtained every 30 seconds. The results show that the TG curve of raw petroleum coke begin to decline, and the CO peak in its 3D infrared spectrogram plot has appeared at the temperature of 1100°C, which proved that the raw petroluem coke (refered to as RPC) has reacted with CO2 at 1100°C. And as the FeSO4 added amount increased,the gasification beginning temperature and initial release time of CO are all in advance,which prove that FeSO4 can enhance the reactivity of PC carbon dioxide gasification.
