英文摘要 | The catalytic behaviors of various nickel boride catalysts in CO hydrogenation were investigated. The chromium was introduced into P-1 nickel boride to examine its effects on CO hydrogenation. The P -1 nickel boride was also supported on active carbon, Florisil and Niobia to increase the dispersion and stability of it. Generally the P-1, P-2 and P- 2W nickel borides were less active than commercial Raney nickel, but the DBNi nickel boride was more active than it. The promoter of chromium not only effectively promoted the activity of P-1 nickel boride but also shifted the product distribution to higher hydrocarbons. The P-1/Niobia catalysts exhibited SMSI behaviors in CO hydrogenation like Ni/Niobia catalysts, and good stability. |
