本文研究了 β、Y 和镁碱沸石及其铁改性对应物的质子形式对松木热解蒸气在氮气气氛下提质的影响。使用双流化床反应器，其中在第一个床中发生松木热解，并在第二个床中进行热解蒸气在沸石上的升级。热解和提质的温度分别为400和450摄氏度。与非催化热解相比，质子形式和铁改性沸石的脱氧反应有所增加。通过脱氧，对有机化合物的选择性增加可以被注意到为更高的水产率和CO形成。 (C) 2010 Elsevier Ltd. 保留所有权利。
In this paper, the influence of the proton forms of beta, Y and ferrierite zeolites and their iron modified counterparts during upgrading of pine wood pyrolysis vapours under nitrogen atmosphere was investigated. A dual-fluidized bed reactor was used where in the first bed pyrolysis of pine wood occurred, and in the second upgrading of the pyrolysis vapours over zeolites was conducted. The temperature for pyrolysis and upgrading was 400 and 450 degrees C, respectively. De-oxygenation reactions over the proton form and iron modified zeolites increased compared to the non-catalytic pyrolysis. The increased selectivity towards organic compounds through de-oxygenation could be noticed as a higher water yield and CO formation. (C) 2010 Elsevier Ltd. All rights reserved.
