低密度一氧化碳低温变换催化剂的研究

摘要

Basing on the domestic Cu-based CO LTS catalyst,reduce bulk desity and MeOH yield of the Cu-based CO LTS catalyst was researched in laboratory.The technological route,component,formula and proper manufacture was used on study on the activity,heat resistance and MeOH yield.Composite property was excellent when the ratio of Cu/Zn at 1.0~1.8 of the catalyst.The results showed that the property of the catalyst better than the Commercial domestic Cu-based CO LTS catalyst and could applied in CO LTS with low H2O/C.%在国产铜系一氧化碳低温变换催化剂基础上,进行了降低堆密度和副产甲醇量的研究,通过对制备催化剂技术路线的研究,选择了组成为铜、锌、铝氧化物的混合物,Cu/Zn为1.0~1.8时催化剂综合性能较好,考察了制备的低密度催化剂的活性、耐热性和甲醇的生成量,并与现有工业催化剂进行了对比,结果表明本研究的低变催化剂性能达到了较先进的技术指标,能够在低水碳比条件下使用。
