[Abstract]:The co-pyrolysis of alkaline lignin and oil shale was studied by means of TG-FTIR and kinetics. The experimental results show that by comparing the theoretical values of the weighted average and the experimental values, it is found that there is a synergistic effect only in the high temperature pyrolysis region in the process of thermogravimetric loss. The kinetic study of pyrolysis shows that alkaline lignin and oil shale can be described by combined first-order reaction kinetics. When the mixing mass ratio is 8:2, the activation energy E of the reaction is the highest in the high-temperature pyrolysis region, which is the inhibition effect. The reaction activation energy E of the other mixing ratio is the lowest in the high temperature pyrolysis region, which is the promotion effect. The functional groups with obvious changes in the co-pyrolysis process were analyzed by infrared spectroscopy. The concentration of CH_4,CO,CO_2,H_2O precipitated during the co-pyrolysis process increased to some extent in the high temperature pyrolysis region. When the mixing ratio is 8:2, the concentration is the lowest.
