Combined Influence of Post-reformer Temperature and Red Mud Catalyst on the Thermo-catalytic Reforming (TCR®) of Digestate
Short Introductive summary
This work investigated the combined influence of post-reformer temperature and addition of red mud as a catalyst in the thermocatalytic reforming (TCR®) of digestate. Increasing the post-reformer temperature increases the gas yield and reduces the yields of the other products. Moreover, increase in the post-reformer temperature also leads to increase in the hydrogen fraction of the gas. Adding red mud to the feedstock tends to increase the gas and the product water yields, and decrease the char yield, while having no significant influence on the oil yield. The influence of the addition of red mud is seen to be more pronounced at a lower post-reformer temperature. Hence, the combined influence of increasing the post-reformer temperature and addition of red mud is a significant decrease in the char yield, decrease in the oil yield to the same extend as when the varying parameter is only post-reformer temperature, slight decrease in the process water yield and increase in the gas yield. Another notable combined influence of the two variables studied is the significant increase in the hydrogen fraction of the gas.
