Desulfurization of Petroleum Coke via Alkali Calcination

Abstract:

Alkali desulfurization of petroleum coke is an important technology, can improve the performance of the final products of petroleum coke, while reducing air pollution. This paper studied the conditions for desulfurization of calcined petroleum coke using NaOH solid powders. The experimental results show that, the grain size in the range of experiment did not seem to influence desulphurization. With the increase of temperature, adding alkali coke ratio, reaction time, desulfurization of petroleum coke rate increased. In the alkali coke ratio of 2, the reaction temperature is 500°C, the reaction time is 2 h, the desulfurization of petroleum coke ratio reached 98.1%. Desulfurization of petroleum coke rate by prolonging the reaction time, to a certain extent, maintains the same level of lowing alkali coke ratio.
