一种使用聚乙二醇作为分散剂的钴基费托催化剂的制备方法
摘要：
本发明公开了一种钴基费托催化剂的制备方法，以重量份计，所述催化剂包括：10-30份Co；0.01-0.1份Pt、Ru、Pd、Rh、Re和/或Ir或它们的氧化物；和100份Al2O3、TiO2和/或SiO2载体；更优选地，所述催化剂包括：15-25份Co；0.02-0.06份Pt、Ru、Pd、Rh、Re和/或Ir或它们的氧化物；和100份Al2O3、TiO2和/或SiO2载体，其中，在催化剂的制备过程中，向前体浸渍液、共沉淀溶液或沉积-沉淀溶液中加入一定量平均分子量为200-20000的聚乙二醇作为分散剂，以促进Co组分在载体中分散。采用本发明方法制备的钴基费托催化剂Co组分分散性变好、Co3O4晶粒变小、催化性能得到改善。
摘要（英）：

The invention discloses a method for preparing a cobalt-based Fischer-Tropsch catalyst. The catalyst comprises the following components in parts by weight: 10-30 parts of Co, 0.01-0.1 part of Pt, Ru, Pd, Rh, Re and/or Ir or oxides thereof, and 100 parts of Al2O3, TiO2 and/or SiO2 carriers; preferably, the catalyst comprises 15-25 parts of Co, 0.02-0.06 part of Pt, Ru, Pd, Rh, Re and/or Ir or oxides thereof, and 100 parts of Al2O3, TiO2 and/or SiO2 carriers, wherein in the preparation process of the catalyst, a certain amount of polyethylene glycol with the average molecular weight of 200-20000 is added into a precursor impregnation liquid, a co-precipitation solution or a deposition-precipitation solution to serve as a dispersing agent, and the component Co is promoted to be dispersed in the carriers. The cobalt-based Fischer-Tropsch catalyst prepared by adopting the method disclosed by the invention has the advantages that the dispersity of the component Co is improved, Co3O4 crystalline grains are small, and the catalytic performance is improved.
