油溶性硫化钼悬浮床催化废弃油脂加氢脱氧研究
Study on Oil-Soluble Molybdenum Sulfide Catalyzed Hydrodeoxygenation of Waste Cooking Oil in a Suspended-Bed Reactor
摘要
Abstract
An oil-soluble molybdenum sulfide catalyst(MS-1)was prepared by a'one-pot'synthesis method and characterized using XRD,FT-IR,XPS,and HR-TEM.The hydrodeoxygenation(HDO)performance toward methyl oleate and the hydrotreating capability for waste oils(with phosphorus,chlorine,and total metal contents of 18.14,138.80,and 173.60 µg/g,respectively)were evaluated in a high-pressure reactor.The results indicate that two-dimensional monolayer MoS2 active species were generated in situ during reaction,and the synthesized catalyst exhibited excellent overall performance.Under the conditions of a catalyst dosage of 380 µg/g,a reaction temperature of 360 ℃,an initial H2 pressure of 4.0 MPa,and a reaction time of 3.0 h,the deoxygenation rates of methyl oleate and waste cooking oil reached 99.2％and 99.7％,respectively.The acid value and bromine value of the waste oil were significantly reduced from 173.60 mgKOH/g and 117.70 gBr/(100 g)to 5.28 mgKOH/g and 5.65 gBr/(100 g).The removal efficiencies of phosphorus,chlorine,and total metals were 92.17％,93.87％,and 96.92％,respectively.关键词
