以Mn_2O_3/Mn_3O_4为氧载体,结合化学链制氧技术,建立了生物质氧气-水蒸气气化产氢工艺,并用Aspen Plus软件进行工艺模拟,研究了水蒸气/生物质质量比(S/B)、氧气/生物质质量比(O/B)和水蒸气/氧载体摩尔比(S/M)对系统性能指标(合成气组成、冷煤气效率、氢气收率、能量效率和效率等)的影响.结果表明,S/B对冷煤气效率、氢气收率、能量效率和效率影响不明显,对合成气组成影响较大,O/B对系统性能指标均有较大影响,S/M只对还原反应器温度有较大影响;当S/B,O/B和S/M分别为0.12,0.25和0.1时,系统总效率和效率分别为74.18%和65.42%,与传统工艺相比,效率提高了8.62%.
The technology of oxygen gas production from biomass by oxygen and steam was established by using Mn_2O_3 / Mn_3O_4 as oxygen carrier combined with chemical oxygen production technology. The process simulation was carried out with Aspen Plus software. The effects of steam / biomass mass ratio (S / B (Syngas composition, cold gas efficiency, hydrogen yield, energy efficiency, and efficiency, etc.) were calculated using the oxygen / biomass mass ratio (O / B) and water vapor / oxygen carrier molar ratio (S / The results show that S / B has no significant effect on the efficiency of cold gas, hydrogen yield, energy efficiency and efficiency, but has a great influence on the composition of syngas, O / B has a great influence on the system performance index, S / M only had a great influence on the temperature of the reduction reactor. When the S / B, O / B and S / M were 0.12, 0.25 and 0.1 respectively, the total efficiency and efficiency of the system were 74.18% and 65.42% Compared to, efficiency increased by 8.62%.
