由于传统颗粒吸附剂床的导热系数较低（0.15-0.5 W m(-1) K-1），气体分离和气体储存过程的性能通常受到诱导吸附热效应的强烈抑制。由固结膨胀天然石墨 (CENG) 基质中原位制作的活性炭 (AC) 制成的整体导热系数增强 (10 W m(-1) K-1) 的整体复合材料已在非等温和非绝热 CO 吸附条件下进行了实验测试。传统饱和步骤的传热强化和工艺性能改进是根据引起的局部温度升高、吸附质突破和吸附能力来描述的。将实验性导电填料的成果与商用 TA70 颗粒活性炭的传统填料床的成果进行了比较。 (c) 2005 Elsevier B.V. 保留所有权利。
Due to the low thermal conductivity of conventional beds of granular adsorbents (0.15-0.5 W m(-1) K-1), performances of gas separation as well as gas storage processes are usually strongly inhibited by the induced adsorptive thermal effects. A monolithic composite of intensified overall thermal conductivity (10 W m(-1) K-1), made of activated carbon (AC) in situ elaborated within a consolidated expanded natural graphite (CENG) matrix has been experimentally tested under both conditions of non-isothermal and non-adiabatic CO, adsorption. Heat transfer intensification and process performances improvements for the conventional saturation step is described in terms of induced local temperature increases, adsorbate breakthrough and sorption capacity. Experimental conductive packing achievements are compared to those of a conventional packed bed of commercial TA70 granular activated carbon. (c) 2005 Elsevier B.V. All rights reserved.
