摘要

采用催化脱氧的方法,可以将Nyamplung油(Calophyllum inophyllum L)转化为绿色柴油。该方法可以使用分级天然沸石负载的双金属催化剂NiAg(NiAg/ZH)。本研究的目的是确定NiAg/ZH催化剂的特性以及将nyamplung油催化脱氧为绿色柴油的最佳条件。通过湿法浸渍合成了总金属浓度为10%、Ni/Ag质量比为4的NiAg/ZH催化剂。X射线衍射、比表面积分析仪和NH3-TPD对催化剂进行了表征。通过改变温度(325、350和375°C)和反应时间(1、2和3小时),催化剂用量为5%,对Nyamplung油进行催化脱氧。使用气相色谱-质谱法分析产物的组成。催化剂的XRD光谱在2θ=22.38°(斜发沸石)、44.42°(Ni)和38.21°(Ag)处显示出峰值。催化剂的表面积为46.7024m2/g,孔体积为0.0813cc/g,平均孔径为6.9632nm,沉积物为1.6882mmol/g。在350°C和3小时内,获得了最佳的nyamplung油催化脱氧反应,汽油选择性为3.51%,煤油选择性为4.73%,绿色柴油选择性为62.02%。

Conversion of Nyamplung Oil into Green Diesel through Catalytic Deoxygenation using NiAg/ZH Catalyst
Nyamplung oil (Calophyllum inophyllum L) can be converted into green diesel by the catalytic deoxygenation method. Bimetallic catalyst NiAg supported by hierarchical natural zeolite (NiAg/ZH) can be used in this method. This study aims to determine the characteristics of the NiAg/ZH catalyst and the optimal conditions for the catalytic deoxygenation of nyamplung oil into green diesel. The NiAg/ZH catalyst was synthesized by wet impregnation with a total metal concentration of 10% and a mass ratio of Ni/Ag of 4. X-Ray Diffraction, Surface Area Analyzer and NH3-TPD characterized the catalyst. Catalytic deoxygenation of Nyamplung oil was carried out by varying the temperature (325, 350 and 375 °C) and reaction time (1, 2 and 3 hours) with a catalyst dosage of 5%. The composition of the product was analyzed using Gas Chromatography-Mass Spectroscopy. The catalyst XRD spectrum showed a peak at 2θ = 22.38° (clinoptilolite zeolite), 44.42° (Ni) and 38.21° (Ag). The surface area of the catalyst is 46.7024 m2/g, the pore volume is 0.0813 cc/g, the average pore diameter is 6.9632 nm, and the deposit is 1.6882 mmol/g. The optimum catalytic deoxygenation of nyamplung oil was obtained at 350 °C and 3 hours with a gasoline selectivity of 3.51%, kerosene 4.73%, and 62.02% green diesel.
