Ni-W/P-SBA-15催化剂加氢脱芳烃研究

以P-SBA-15为载体，担载Ni、W活性组分制备了加氢脱芳烃催化剂。用XRD、BET对该催化剂进行表征。结果表明，该催化剂仍然具有二维晶相结构，较大的比表面积和孔体积及孔径。以含萘质量分数为7%的正十二烷溶液为原料对该催化剂进行了加氢脱芳烃性能研究。结果表明，在磷的负载量为2%（质量分数）时，催化剂具有最佳的脱芳烃性能。脱芳烃的最优工艺条件为：反应温度为320 ℃，压力为4.0 MPa，氢油体积比600，体积空速2.0 h-1。在此条件下，模型化合物的脱芳率可达88.4%。

STUDY ON THE HYDRODEAROMATIZATON PERFORMANCE OF Ni-W/P-SBA-15 CATALYST

A hydrodearomatization(HDA)catalyst was prepared using phosphoric acid modified SBA-15 molecular sieve as carrier and Ni-W as active metals.The characterization results of XRD and BET show that this catalyst possesses two-dimensional crystal structure and the characteristics of meso-porous material.The HDA reaction performance of the catalyst was investigated using dodecane containing 7% naphthalene as feed.Results showed that catalyst having a phosphor mass fraction of 2% exhibited the optimal HDA performa...
