Abstract

This research evaluated a catalyst activity for hydrodesulfurization (HDS) of a petroleum fraction and the mixture of partially hydrodeoxygenated bio-oil (HBO), which was hydrodeoxygenated woody tar (HWT) and the petroleum fraction, which was light gas oil. As results, 340oC of reaction temperature and 2 hours of reaction period provide positive influence on the catalyst activity. Oxygen and nitrogen compounds in bio-oil exhibit an inhibiting effect on the HDS. Synthesized catalysts supported on titanium-rich and pure titania carriers indicate higher activity than those supported on pure alumina, since TiO 2 acts as an electronic promoter in catalysts. The electronic promotion of Mo by Ti has a limitation, accordingly, 310CoMoAT (1:0.75) catalyst presents the best catalytic behavior. The approach from this research can contribute a direction for further improvement of co-processing bio-oil productions as a sustainable fuel invention.

CoMo/Al2O3-TiO2催化剂协同加工生物油加氢脱硫的潜在活性评价

本研究考察了石油馏分和部分加氢脱氧生物油(HBO)(加氢脱氧木质焦油(HWT))与石油馏分(轻质油)混合物加氢脱硫(HDS)的催化剂活性。结果表明，反应温度为340oC，反应时间为2h对催化剂活性有积极影响。生物油中的氧、氮化合物对HDS有抑制作用。负载在富钛载体和纯钛载体上的合成催化剂比负载在纯氧化铝载体上的合成催化剂具有更高的活性，这是因为tio2在催化剂中起到了电子促进剂的作用。Ti对Mo的电子促进有一定的局限性，因此，310CoMoAT(1:0.75)催化剂表现出最好的催化性能。本研究的方法可以为进一步改进生物油协同加工生产作为可持续燃料的发明提供方向。
