用pd修饰的介孔催化剂可持续地将生物柴油废甘油转化为丙烯醛
可持续的生物柴油行业依赖于将生物炼制副产品甘油转化为有价值的化学品。介绍了一种用于甘油选择性脱水制丙烯醛的湿式浸渍Pd/SBA-15催化剂。使用各种分析技术来确认催化剂的物理化学特性,包括X射线衍射、脉冲CO化学吸附、BET表面积、TEM和H2-TPR。结果表明,Pd纳米粒子以均匀分散体的形式掺入SBA-15中。Pd/SBA-15催化剂具有较高的表面积和足够的Bronsted酸性位点,可以提高丙烯醛的选择性,降低中毒易感性。使用气相操作的固定床反应器来验证所制备的酸催化剂选择性地将甘油转化为丙烯醛的效率。研究发现,负载在SBA-15催化剂上的2 wt%钯纳米颗粒在320°C下表现出89.6%的甘油转化率和64.2%的丙烯醛选择性。发现酸性位点(Lewis&;Brønsted)、均匀的Pd纳米颗粒分散体和载体(即SBA-15)赋予了其优异的催化活性。各种反应参数,包括温度、TOF、Pd负载量和重量小时空速,也会影响催化活性。
