摘　　要：以贝壳粉为载体制备了负载型固体碱催化剂,并用于生物柴油的合成。确定以贝壳粉为载体的固体碱生物柴油催化剂的最佳制备条件为:焙烧温度600℃、活性组分负载量20%;其催化合成脂肪酸甲酯的最佳反应条件为:催化剂用量为原料油的1%～2%、反应温度60～65℃。所制固体碱生物柴油催化剂比表面积大,抗酸、抗水性能好,应用前景良好。A solid base catalyst with shell powder as carrier was prepared and applied to the biodiesel production. The optimum preparation conditions for the catalyst were determined as sintering temperature of 600℃ and loading amount of active components of 20%. The optimum reaction conditions for biodiesel production were determined as catalyst amount of 1% -2 % of oil and reaction temperature of 60-65℃. The obtained solid base catalyst, which possessed huge specific surface area and good antiacid and waterproof performance, had excellent application prospect.
