  • In this study, an Fe-Zr oxide (Fe2O3 and ZrO2) modified by K2CO3 was used as the oxygen carrier (denoted as K3-Fe70Zr30) to analyze the effects of the temperature and the char mass ratio on the gas yield and composition during coal char chemical looping gasification for hydrogen production. The results of temperature-programmed experiments show that the reaction of oxygen carrier and coal char starts at 500 ℃, and the reaction rate increases sharply after 750 ℃; the reduced oxygen carrier begins to react with steam when the temperature reaches 400 ℃, and the concentration of hydrogen significantly increases after 500 ℃. The results of isothermal experiments indicate that the reaction rate accelerates with increasing reaction temperature. However, the ratio of CO/CO2 volume ratio increases, resulting in the H2 production decreases as the temperature raises. In addition, an increase in char ratio increases the ratio of CO/CO2 volume ratio in the outlet gas increases, which leads to the hydrogen production firstly increase and reaches a maximum value of 1.734 L/g, and then decrease. The activity of oxygen carrier can keep stable during the first 2 redox cycles, but it decreases in the 3rd cycle. The activity can be renewed by supplement of K2CO3, which suggests that the loss of K2CO3 can contribute to the decreased activity.
