一种使用碳酸甘油酯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碳酸甘油酯作为分散剂，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 by glycerol carbonate as a dispersant. The catalyst comprises, by weight, 10-30 parts of Co, 0.01-0.1 parts of Pt, Ru, Pd, Rh, Re and/or Ir or oxides thereof, and 100 parts of Al2O3, TiO2 and/or SiO2 carrier. Preferably, the catalyst comprises, by weight, 15-25 parts of Co, 0.02-0.06 parts of Pt, Ru, Pd, Rh, Re and/or Ir or oxides thereof, and 100 parts of Al2O3, TiO2 and/or SiO2 carrier. The method of the catalyst comprises the following steps of adding a certain amount of glycerol carbonate as a dispersant into a precursor impregnation liquid, a coprecipitation solution or a deposition-precipitation solution so that dispersion of the Co component in the carrier is promoted. The cobalt-based Fischer-Tropsch catalyst has the advantages of good Co component dispersity, small Co3O4 crystal grain size and good catalytic performance.
