Annotation:
In the course of the work, mono- and bimetallic systems based on natural minerals, kaolin and halloysite aluminosilicate nanotubes were studied for the first time. The developed systems are characterized by up-to-date physicochemical analyzes. The catalytic activity was studied in a laboratory Fischer-Tropsch synthesis plant with an integral flow-through reactor at the feed flow rate of 5 nl/(h∙gcat), CO/H2 ratio = 1/2, temperature 210 °C, pressure 2 MPa. As a result, it was shown that the efficiency of the obtained nanostructured systems strongly depends on the nature of the carrier. Kaolin-based catalysts show a higher activity, but their selectivity with respect to synthetic C5+ products is significantly higher for a catalyst based on halloysite.
