Bifunctional Cobalt-Containing Catalytic Systems Based on SAPO-11 Molecular Sieves in Fischer–Tropsch Synthesis of Fuels

The study investigated, for the first time with respect to Fischer–Tropsch synthesis of fuels, cobalt-containing catalytic systems based on SAPO-11 molecular sieves with differing secondary porous structure characteristics. Various methods, such as XRD, low-temperature nitrogen adsorption/desorption, SEM, TEM, H 2 -TPD, and NH 3 -TPD, were used to characterize the prepared catalysts, which were subsequently examined in hydrocarbon synthesis at 2.0 MPa, 240°C, and gas WHSV = 1000 h –1 . The study demonstrated good prospects for micro/mesoporous-structured SAPO-11 as an acid catalyst component for fuel production.
