Abstract

Biodiesel production from rapeseed oil and methanol via transesterification reaction facilitated by various monometallic catalyst supported on natural zeolite (NZ) was investigated. The physicochemical characteristics of the synthesized catalysts were studied by X-ray diffraction (XRD), Brunauer-Emmett-Teller method (BET), temperature-programmed-reduction in hydrogen (H-TPR), temperature-programmed-desorption of ammonia (NH-TPD), Scanning Electron Microscope equipped with EDX detector (SEM-EDS), and X-ray photoelectron spectroscopy (XPS) methods. The highest activity and methyl ester yields were obtained for the Pt/NZ catalyst. This catalyst showed the highest triglycerides conversion of 98.9% and fatty acids methyl esters yields of 94.6%. The activity results also confirmed the high activity of the carrier material (NZ) itself in the investigated reaction. Support material exhibited 90.5% of TG conversion and the Fatty Acid Methyl Esters yield (FAME) of 67.2%. Introduction of noble metals improves the TG conversion and FAME yield values. Increasing of the metal loading from 0.5 to 2 wt.% improves the reactivity properties of the investigated catalysts.

摘要

研究了以天然沸石（NZ）负载的各种单金属催化剂促进菜籽油与甲醇通过酯交换反应生产生物柴油的过程。通过X射线衍射（XRD）、布鲁诺尔-埃米特-泰勒法（BET）、氢气程序升温还原（H-TPR）、氨程序升温脱附（NH-TPD）、配备能谱仪的扫描电子显微镜（SEM-EDS）以及X射线光电子能谱（XPS）等方法对合成催化剂的物理化学特性进行了研究。Pt/NZ催化剂具有最高的活性和甲酯产率。该催化剂的甘油三酯转化率最高可达98.9%，脂肪酸甲酯产率为94.6%。活性结果还证实了载体材料（NZ）本身在所研究反应中的高活性。载体材料的甘油三酯转化率为90.5%，脂肪酸甲酯（FAME）产率为67.2%。引入贵金属提高了甘油三酯转化率和脂肪酸甲酯产率值。将金属负载量从0.5 wt.%增加到2 wt.%可改善所研究催化剂的反应性能。
