Abstract:
In this paper, the effects of temperature and catalysts Fe, Mg, Co, and different catalyst addition ratios on hydrogen production from the pyrolysis of tobacco pole were explored to find the best reaction conditions. The results show that the temperature is conducive to the improvement of gas yield and total conversion. The total conversion obtained maximum yield at 700 ℃. The increase in the amount of supported Fe increases the gas yield greatly. When the addition ratio is 15%, the total conversion reaches 83.19%. Mg catalyst can promote the generation of hydrogen. For the composite catalyst, the Fe-Mg catalyst system increases the gas yield, and the H
2 content is the largest when the catalyst ratio is 15%Fe+0.8Mg, which is 113.48 mL/g. After the 15%Fe+0.8%Mg catalytic system continues to be loaded with Co catalyst, as the Co loading increases, the total conversion increases, when the addition ratio is 15% Fe+0.8%Mg+0.9%Co. The total conversion reached the maximum, 84.31%, and the hydrogen content decreased, so the loading of the Co catalyst was detrimental to the generation of hydrogen.
