摘要

An investigation was conducted to analyze the influence of microwave power, the addition of char, and temperature on the pyrolysis of tissue paper for gas generation in a silicon carbide reactor. At a fixed final pyrolysis temperature of 600 ℃, the primary components of the syngas produced were CO and CO₂, constituting approximately 80% of the total, with CH₄ and H₂ making up 15–20%. The results showed that increasing microwave power led to higher release temperatures for CO and CO₂. Optimal gas production of 18.8 wt% (130 ml/g) was achieved at 600 ℃, 700 W.Adding 10–20% pyrolytic char can significantly increase the gas yield from pyrolysis, but has little effect on the composition of the produced gas. When the pyrolysis temperature is raised from 600 °C to 800 °C, there is a significant increase in both the hydrogen content and the volume of syngas. The volume of gas produced is 193 ml/g with 20% char addition at 800 °C.
