预热液体石蜡对CuZnAl催化剂合成低碳醇的影响OA北大核心CSCDCSTPCD
Effect of preheating liquid paraffin on synthesis of higher alcohols by CuZnAl Catalyst
在完全液相法中,采用预热的液体石蜡为热处理和反应介质,以不同的热处理温度制备了CuZnAl催化剂.利用X射线衍射、H2程序升温还原、NH3程序升温脱附、氮吸附和X射线光电子能谱对催化剂进行了表征.结果表明,液体石蜡进行加热预处理可以增加催化剂中Cu晶粒度和孔径,改变Cu+的存在形态,提高表面Cu/Zn比例,使催化剂具有适宜的弱酸量,从而促进了C2+OH的生成.对液体石蜡预热处理后,在250℃和280℃进行热处理的催化剂C2+OH/ROH分别达到了…查看全部>>
The CuZnAl catalyst prepared by complete liquid-phase method was heat-treated under different temperature with paraffin which was pretreated in advance as heat-treatment and reaction medium. All catalysts were characterized by XRD, H2-TPR NH3-TPD, N2 adsorption and XPS. The results showed that the pretreatment of liquid paraffin could increase the grain size of Cu and pore size of the catalyst, change the existing form of Cu+, improve the Cu/Zn ratio on the …查看全部>>
