本文介绍了在鼓泡流化床内木质纤维素原料的快速热解转化。研究了生物质进料中生物聚合物（即半纤维素、纤维素和木质素）的分布对热解生物油和焦的产率和性质的影响。虽然使用鼓泡流化床反应器不可能将化学现象与传递现象解卷积，但半纤维素在生物质进料中的关键作用通过以下方式说明：（i）其对热解水的产生的影响，（ii）其对有机物的产生的影响，显然是由于其与木质素的键合关系，和（iii）其抑制炭孔隙率发展的能力，而纤维素似乎是生物炭微孔特性的前体。这些结果是感兴趣的选择合适的原料，旨在生产生物油和焦炭作为燃料和土壤改良剂，分别。(C)2013爱思唯尔有限公司保留所有权利。
The paper describes the fast pyrolysis conversion of lignocellulosic materials inside a bubbling fluidized bed. The impact of biopolymers distribution in the biomass feed, namely hemicelluloses, cellulose and lignin, on the yields and properties of pyrolytic bio-oils and chars was investigated.Although it is not possible to deconvoluate chemical phenomena from transfer phenomena using bubbling fluidized bed reactors, the key role of hemicelluloses in biomass feedstocks was illustrated by: (i) its influence on the production of pyrolytic water, (ii) its impact on the production of organics, apparently due to its bonding relationship with the lignin and (iii) its ability to inhibit the development of chars porosity, while the cellulose appeared to be the precursor for the microporous character of the biochars. These results are of interest for the selection of suitable feedstocks aimed at producing bio-oil and char as fuels and soil amendment, respectively. (C) 2013 Elsevier Ltd. All rights reserved.
