摘要
研究了 Ni助剂对于调变Co/AC催化剂表面富碳缺氢化学环境的作用,考察了 Ni掺杂对CO加氢反应性能的影响.采用物理吸附、程序升温还原、化学吸附、高分辨透射电子显微镜(HRTEM)、X-射线衍射(XRD)和X-射线光电子能谱(XPS)对催化剂进行了表征.结果表明Co/AC催化剂中掺杂Ni助剂后,随着Ni助剂质量分数由0％增加至3％,C6+高碳醇在醇类产物的分布由31.3％提高至51.7％.Ni掺杂为促进高碳醇的醇分布提供了新思路.
Abstract
The production of higher alcohols using Co/AC catalysts is difficult due to the strong CO adsorp-tion capacity and weak H2 adsorption capacity of the catalyst.To address this issue,we incorporated metal Ni,which has a strong H2 adsorption capacity,to enhance the catalyst's adsorption capacity for H2,and explore the effect of Ni on the hydrogenation of Co/AC to produce higher alcohols.By combining X-ray diffraction,physical adsorption,chemical adsorption,and other characteristics,we were able to examine the role of Ni in Co/AC catalyst.Our results indicated that with the incorporation of 3％Ni promoter con-tent,the distribution of higher alcohols in the alcohol products increased from 31.3％to 51.7％.The ad-dition of Ni provided a new way to promote the distribution of higher alcohols.The incorporation of Ni with Co/AC catalysts is a promising approach to enhance the performance of the catalyst and promote the distribution of higher alcohols,which in turn will contribute towards achieving these objectives.
