Bio-ethanol is a renewable fuel and can be converted to high-values chemicals. This study showed that more aromatics and gas products could be obtained at a low weight hourly space velocity (WHSV) than that at high WHSV using HZSM-5 and Ni/HZSM-5 catalysts. A low WHSV offered an increased tendency to build up aromatics and paraffins. Real bio-ethanol broth was tested and gave the similar result as pure ethanol solution. That catalysts could retain full catalytic activity after 168 h in reaction provides evidence for their long stability. This study advantageously demonstrates a promising approach to generate high-value products from bio-ethanol.

生物乙醇是一种可再生燃料，可以转化为高价值化学品。这项研究表明，使用HZSM-5和Ni / HZSM-5催化剂，在低重量时空速（WHSV）下可以获得比在高WHSV下更多的芳烃和气体产物。低的WHSV提供了增加形成芳族化合物和石蜡的趋势。测试了真实的生物乙醇肉汤，其结果与纯乙醇溶液相似。催化剂在反应168小时后可以保留全部催化活性，为它们的长期稳定性提供了证据。这项研究有利地证明了从生物乙醇生产高价值产品的有前途的方法。
