COBALT NANOCATALIZER OF FISHER-TROPSH SYNTHESIS, LOCALIZED IN POROUS MATERIAL, AND METHOD OF ITS OBTAINING

摘要

FIELD: chemistry.;SUBSTANCE: cobalt Fischer-Tropsch synthesis nanocatalyst is described localized in a porous material. The catalyst was prepared by a sol-gel process using an organogel as a matrix, which is a linear amphiphilic polymer. The active component is used as a core, and the porous material is used as a shell. The active component comprises the first metal component in the form of Co, the second metal component selected from Ce, La and Zr, and the third metal component selected from Pt, Ru, Rh and Re. The catalyst comprises the first metal component of 10-35 wt %, the second metal component of 0.5-10 wt %, the third metal component of 0.02-2 wt %, and the carrier is the rest. The carrier is a porous material of a spherical shape. The porous material has a pore size of 1-20 nm and a specific surface of 300-500 m²/g, the particle diameter of the active component core is 0.5-20.0 nm.;EFFECT: low methane selectivity and good selectivity of C₅₊.;9 cl, 1 dwg, 1 tbl, 12 ex
