摘要：
Promotion effects of La and Ce on Ni/γ-Al2O3 catalysts in hydrotreating of crude 2-ethylhexanol were studied. The results indicated that La was helpful to increase the content of octahedral Ni2+ ions while Ce had no such modification effect. Activity test indicated that catalysts modified by La exhibited higher activities compared with the unmodified and Ce modified catalysts. The sample modified with 1.5 wt% La presented the best activities in a wide range of space velocity from 1.5 to 12 h−1.
