The PTA-NiMo/ZSM-5 catalyst impregnated with phosphotungstic acid (PTA) was designed for the transformation of Jatropha oil into benzene, toluene, and xylenes (BTX) aromatics. The produced catalyst was characterized by N adsorption-desorption, powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), and the temperature-programmed desorption of ammonia (NH-TPD). The catalytic performance was evaluated by gas chromatography (GC). The liquid products were 70 wt% of the feed oil, and the majority of the liquid products were BTX. The aromatization activity of the catalyst was improved by the addition of PTA and the hierarchical process. The favorable PTA amount was 20 wt% and the yield of BTX was 59 wt% at 380 °C, 3 MPa, H/oil (v/v) = 1000 and LHSV = 1 h over the PTA20-NiMo/HZ0.5 catalyst (PTA 20 wt%) without sulfurization.
采用浸渍磷钨酸（PTA）的 PTA-NiMo/ZSM-5 催化剂用于将麻疯树油转化为苯、甲苯和二甲苯（BTX）芳烃。所制备的催化剂通过 N2 吸附-解吸、粉末 X 射线衍射（XRD）、傅里叶变换红外（FT-IR）、X 射线光电子能谱（XPS）和氨程序升温脱附（NH-TPD）进行了表征。通过气相色谱（GC）评估了催化性能。液体产物占进料油的 70wt%，大部分液体产物为 BTX。通过添加 PTA 和分级过程提高了催化剂的芳烃化活性。最佳的 PTA 用量为 20wt%，在未硫化的条件下，于 380°C、3MPa、H/oil（v/v）=1000 和 LHSV=1h-1 的条件下，PTA20-NiMo/HZ0.5 催化剂（PTA 20wt%）的 BTX 收率为 59wt%。
