HUANG Xinjiang, HU Yi, YU Dinghua, et al. Effect of fusel on dehydration reaction of ethanol to ethylene catalyzed by La/HZSM-5[J]. CIESC Journal, 2011, (1): 97-102.DOI:
isobutyl alcohol and isoamyl alcohol on the ethanol dehydration to ethylene catalyzed by 2.0% La/HZSM-5 were investigated.With the characterization of NH3-TPD
BET and TG
the reaction mechanism was analyzed.The three fusel alcohols can result in dehydration
and produce olefin products that are easily polymerized.These products have significant effects on the performance of the catalyst.The coke on the catalyst is aggravated as the number of carbon atoms in the fusel increases
so that the catalytic performance is worse.Compared with HZSM-5
2.0%La/HZSM-5 has larger surface area and pore volume
