Recent advance in directing synthesis of aromatic hydrocarbons from syngas via Fischer-Tropsch route

Aromatics, as the important industrial basic chemicals, can be prepared by direct or indirect conversion of syngas. Compared with the indirect conversion method, the direct syngas to aromatics route (STA) has the advantages of high feedstock conversion, short process, and easy product separation. In this paper, we mainly introduce the progress of research on the direct syngas to aromatics by Fischer-Tropsch route, and focus on the effects of the metal oxide coupled molecular sieve bifunctional catalysts on the catalytic reaction performance, such as the selection of Fischer-Tropsch active components and additives, molecular sieve acidity modulation and pore structure regulation; Then we summarize the influence of reaction temperature, pressure, air velocity, hydrogen to carbon ratio and other parameters on the reaction performance. At last, based on the mechanisms of STA reaction and catalyst deactivation, the method for improving the activity and stability of STA catalysts is discussed.
