生物柴油的K2CO3负载水滑石催化制备工艺（Preparation Technology of Biodiesel Using K2CO3 Loaded Hydrotalcite Catalyst）
生物柴油 固体碱催化剂 K2CO3
2009/5/22
采用浸渍法制备K2CO3负载水滑石生物柴油催化剂，确定制备条件为：K2CO3负载量20%、共混温度80℃、焙烧温度600℃、焙烧时间6h。用该催化剂催化菜籽油转酯化制备生物柴油，考察了反应时间、醇油比、催化剂用量及反应温度对反应转化率的影响，采用气相色谱测定了脂肪酸甲酯的转化率。通过单因素试验确定了菜籽油转酯化反应的条件为：反应温度60℃，醇油比12，反应时间60min，催化剂用量4%，转化率达9...
