Optimization of ethylene production from ethanol dehydration using Zn-Mn-Co/HZSM-5 by response surface methodology
|
Abstract:
The effects of reaction temperature, ethanol concentration and weight hourly space velocity (WHSV) on the ethylene production from ethanol dehydration using zinc, manganese and cobalt modified HZSM-5 catalyst were investigated by response surface methodology (RSM). The results show that the most significant effect among factors was reaction temperature and the factors have interaction. The optimum conditions were found as 34.4% ethanol concentration, 261.3 °C of reaction temperature and 1.18 h?1 of WHSV, under these conditions the yield of ethylene achieved 98.69%.
