碳化硅/氮化硅载体及其制备方法、费托合成催化剂及其制备方法和应用
摘要：
本发明属于费托合成催化剂技术领域，尤其涉及一种碳化硅/氮化硅载体及其制备方法、费托合成催化剂及其制备方法和应用；以碳化硅/氮化硅载体的总重量为100wt％计，碳化硅/氮化硅载体包括如下百分含量的各组分：55-72wt％的氮化硅，25-40wt％的碳化硅，1-12wt％的氧化铝；费托合成催化剂包括：20-60wt％的活性组分，0-20wt％的助催化剂，30-50wt％的所述碳化硅/氮化硅载体。本发明通过选择碳化硅/氮化硅载体可使所得费托合成催化剂具有高温稳定性、良好的抗磨耗性以及高的费托合成活性。
摘要（英）：

The invention belongs to the technical field of Fischer-Tropsch synthesis catalysts, and especially relates to a silicon carbide/silicon nitride carrier, a preparation method thereof, a Fischer-Tropsch synthesis catalyst, and a preparation method and an application of the catalyst. 100 wt% of the silicon carbide/silicon nitride carrier comprises 55-72 wt% of silicon nitride, 25-40 wt% of silicon carbide and 1-12 wt% of alumina; and the Fischer-Tropsch synthesis catalyst includes 20-60 wt% of an active component, 0-20 wt% of a cocatalyst and 30-50 wt% of the silicon carbide/silicon nitride carrier. The silicon carbide/silicon nitride carrier is selected to make the Fischer-Tropsch synthesis catalyst have the advantages of good high temperature stability, good arbrasion resistance and high Fischer-Tropsch synthesis activity.
