SBA-15在环己烷选择性氧化中的催化研究
Selective Oxidation of Cyclohexane Catalysis in SBA-15
摘要
Abstract
Au/SBA-15, Au-Ni/SBA-15, Au-Co/SBA-15 catalyst were prepared by in situ synthesis and deposition synthesis, and the crystal structure and metal dispersion were characterized by XRD, TEM-EDS and other means.In the condition of absence of any organic solvents or additives, air was used as the oxidant to oxidize cyclohexane selectively, and catalytic properties were evaluated in this reaction.It is found that good synergistic effect exists in the two-metal catalysts for selective oxidation of cyclohexane to cyclohexanone and cyclohexanol, which can greatly increase the catalytic activity.The conversion rate of cyclohexane is 22.1 %, and the total selectivity of cyclohexanol and cyclohexanone is 95.1 %, when Au-Co/SBA-15 was used as the catalyst in the condition of 3 MPa, 423 K and 2 hours.关键词
