摘要

随着化石燃料储量的不断减少、油价的持续攀升以及环境问题的日益严重，人们对替代能源展开了深入研究。Cu基催化剂是合成气直接制低碳醇（C

醇，简写为“C

醇”）的重要催化剂之一，但存在甲醇占比较高、乙醇和C

醇占比较低的问题。采用完全液相法制备了一系列不同

(Al):

(Ga)的CuZn催化剂（CuZnAlGa），采用XRD、N

吸/脱附和H

-TPR等方法对催化剂的物相组成、织构性质和还原性等进行了表征，并在浆态床反应器中进行了合成气加氢制C

醇反应，分析了CuZnAlGa的催化性能。结果表明，

(Al):

(Ga) = 1:2时，催化剂表面氧空位含量最高，表现出最佳的催化性能。在553 K、4.0 MPa和

(CO) = 2:1条件下反应168 h，CO转化率达11.54%，乙醇和C

醇在总醇中的占比（物质的量分数）分别为71.25%和86.88%。

Abstract

With the continuous reduction of fossil fuel reserves

continuous rise of oil prices and increasingly serious environmental problems

people have conducted in-depth research on alternative energy sources. Cu-based catalysts are one of the most important catalysts for the direct conversion of syngas to higher alcohols (C

alcohols

abbreviated as “C

alcohols”). However

there is a problem of high proportion of methanol and low proportions of ethanol and C

alcohols. A series of CuZn catalysts with varying

(Al):

(Ga) (CuZnAlGa) were synthesized by complete liquid-phase method. Properties such as phase compositions

textural properties and reducibilities were characterized by XRD

adsorption/desorption

-TPR

etc. The syngas hydrogenation to C

alcohols was carried out in a slurry bed reactor

and catalytic performances of CuZnAlGa were analyzed. The results show that the catalyst with

(Al):

(Ga) = 1:2 has the highest oxygen vacancy content and shows the best catalytic performance. After reacting for 168 h under the reaction conditions of 553 K

4.0 MPa and

(CO) = 2:1

the CO conversion rate reaches 11.54%

and the proportions (mole fractions) of ethanol and C

alcohols in the total alcohol are 71.25% and 86.88%

respectively.
