这项工作的目的是开发从木糖生产糠醛的新方法。它将相对便宜的多相催化剂 (Amberlyst 70) 与在半间歇条件下使用氮气同时进行糠醛汽提相结合。与蒸汽相比，氮气在冷凝时不会稀释气相流。该系统可以汽提从木糖转化而来的 65% 的糠醛，并且冷凝液的选择性几乎为 100%。此外，高初始木糖含量导致形成两个水-糠醛相，这可以降低进一步的纯化成本。对于不同的木糖负载量，可以保持沿着汽提的恒定液汽平衡。对实验数据进行建模以获得液-汽传质系数。该值可用于类似反应系统中稳态连续条件下的未来研究。 (C) 2011 Elsevier Ltd. 保留所有权利。
The aim of this work deals with the development of new approaches to the production of furfural from xylose. It combines relatively cheap heterogeneous catalysts (Amberlyst 70) with simultaneous furfural stripping using nitrogen under semi-batch conditions. Nitrogen, compared to steam, does not dilute the vapor phase stream when condensed. This system allowed stripping 65% of the furfural converted from xylose and almost 100% of selectivity in the condensate. Moreover, high initial xylose loadings led to the formation of two water-furfural phases, which could reduce further purification costs. Constant liquid-vapor equilibrium along stripping could be maintained for different xylose loadings. The modeling of the experimental data was carried out in order to obtain a liquid-vapor mass-transfer coefficient. This value could be used for future studies under steady-state continuous conditions in similar reaction-systems. (C) 2011 Elsevier Ltd. All rights reserved.
