【摘要】 采用Gibbs自由能最小化法对Fe₂O₃氧载体四氢呋喃（C₄H₈O）部分氧化制合成气反应进行热化学平衡计算,考察了反应物摩尔比n（Fe₂O₃）:n（C₄H₈O）、温度和压力等因素对Fe₂O₃氧载体C₄H₈O部分氧化制合成气反应产物的影响,结果表明:随反应物摩尔比增大,合成气摩尔分数及氢碳比（H₂/CO）先增大后减小,在反应物摩尔比为1时,合成气摩尔分数及氢碳比最大;随温度升高,合成气摩尔分数及氢碳比明显增大,800—1 200℃时,合成气摩尔分数较高,氢碳摩尔比在1附近,有利于合成气的制备;随压力增加,合成气摩尔分数及氢碳比减小,低压有利于合成气的制备。在反应物摩尔比为1,800—1 200℃、常压条件下,合成气摩尔分数> 95%、氢碳比> 0. 94。更多还原

【Abstract】 The thermodynamic analysis of syngas production from chemical looping partial oxidation of tetrahydrofuran with Fe₂O₃ oxygen carrier was calculated by the Gibbs free energy minimization method.The effects of Fe₂O₃ to tetrahydrofuran ratio,temperature and pressure on composition and proportion of the products were investigated.The results showed that with the increasing of Fe₂O₃ to tetrahydrofuran ratio,the components of syngas and H₂ to CO ratio increased firstly then decreased,and the suitable ratio of Fe₂O₃ to tetrahydrofuran was 1,the components of syngas and H₂ to CO ratio reached the highest level,favorable to acetylene and syngas production.With the increasing of temperature,the components of syngas and H₂ to CO ratio increased obviously.At 800-1 200 ℃,the components of syngas was relatively high stable and the ratio of H₂ to CO was about 1,favorable to syngas production.With the increasing of pressure,the components of syngas and H₂ to CO ratio decreased,low pressure was favorable for syngas production.Under the conditions of Fe₂O₃ to tetrahydrofuran ratio of 1,800-1 200 ℃,ordinary pressure,the components of syngas is more than 95%,and the ratio of H₂ to CO is more than 0.94.更多还原
