Abstract
Fischer–Tropsch synthesis (FT) is a well-known industrial process able to convert syngas mixture in useful products as long chain hydrocarbons. FT can be applied also in the conversion of CO2/H2 mixtures and, for this reason, this technology is attracting interest in the field of biomass conversion processes. Nevertheless, different catalytic materials respect the traditional process are needed for the activation of the stable CO2 molecule. In this study, a series of ternary hydrotalcites (HTlc) were prepared with and without ultrasound to obtain active Fe-based catalysts for the Fischer–Tropsch synthesis. All the samples in fresh and used form were characterized by XRPD, ICP-OES, SEM, TEM, FT-IR, BET, TPR and TG and tested in a fixed bed reactor. HTlc can be easily prepared and essentially consist of mixed metal hydroxides, where specific metal atoms are homogeneously dispersed at an atomic level.Pubblicazioni consigliate
