Abstract: The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.

Abstract translation: 本发明涉及一种通过溶胶 - 凝胶法制备含磷磷 - 氧化铝载体的方法和一种钴/磷 - 氧化铝催化剂，其中钴作为活性成分负载在磷 - 氧化铝载体上。 磷 - 氧化铝载体通过溶胶 - 凝胶法制备，具有宽的比表面积，具有双峰孔径分布和高钴分散性，从而能够增加热和质量传递，通过改变氧化铝的表面性能来稳定结构，并减少 由于在FT反应期间钴组分的氧化降低导致的失活速率。 当在催化剂上进行费 - 托反应（F-T）时，催化剂保持优异的热稳定性，抑制在F-T反应期间由于水的产生而失活，并且还导致一氧化碳相对较高的转化率和液体烃的稳定选择性。
