At present the experimental study on carbon dioxide dry capture is mainly giv en priority to with mechanism, in industrialized device research has not seen the report. With supported solid carbonate as the adsorbent, the experimental study on carbon dioxide capture from flue gas is carried out with fluidized bed adsorption reactor. Experiment measured the effect on the adsorption of different adsorbent, temperature, reaction time, and adsorbent regeneration performance test. The results showed that the adsorbent is the solid sodium carbonate, in the range of 65 'C-85 'C. Moreover, absorption time is about 4 min-10 min. In this case, the removal rate of carbon dioxide can reach 97. 5%, and adsorbent can reach steady state after 10 times re generation, so adsorbent can use long-term.%用沉淀法制备了涂覆在微通道内壁面的Ni/Al2O3催化剂,在自行搭建的实验系统上进行了微通道内甲烷/湿空气催化重整的实验研究,考察了催化壁面温度、空碳比及甲烷体积流量对甲烷/湿空气重整转化效率的影响,并与数值计算结果进行对比.结果表明,随着催化温度的升高,甲烷转化率不断升高；相同水碳比下,甲烷的催化转化率随着空碳比的增大而增大;随着甲烷体积流量的增大,甲烷转化效率呈现先增大后减小的变化规律.反应温度为1 023 K,甲烷体积流量为20 mL/min时,实验所得甲烷转化率达到最大值,为61.3％.
