| description | Preparation, characterization and catalytic activity test of CoMo/ZnO catalyst for steam reforming of ethanol
have been investigated. The catalysts preparation was carried out by impregnation of Co and/or Mo onto ZnO
sample. Water excess was used in ethanol feed for steam reformingprocess under mol ratio of ethanol:water (1:10).
Characterizations of catalysts were conducted by analysis of metal content using Atomic Absorption
Spectroscopy (AAS). Determination of catalysts acidity was conducted by gravimetric method of adsorption of
pyridine base. Catalytic activity test on ethanol conversion using steam reforming method was conducted in a semiflow
reactor system, at a temperature of 400°C, for 1.5 h under N2 flow rate of 10 mUmin. Gas product was
analyzed by gas chromatographwith TCDsystem.
The results of catalysts characterizations showed that the impregnation of Co and/or Mo metals on ZnO
sample increased its acidity and specific surface area. The content of Co in Co/ZnO and CoMo/ZnO catalysts was
1.14 and 0.49 wt%. TheMo content in CoMo/ZnOcatalyst was 0.36 wt%. The catalytic activity test result on ethanol
conversion showed that the ZnO, Co/ZnO, and CoMo/ZnO catalysts produced gas fraction of 16.73, 28.53, and
35.53 wt%, respectively. The coke production of ZnO, CoIZnO, and CoMo/ZnOcatalysts was 0.86, 0.24, and 0.08
wt%, respectively. The gas products consistedmainly of hydrogen.
