- Abstract
One-step CO2 conversion to liquid hydrocarbons (Emission-to-Liquid) was carried out at 340°C and 10.0 MPa in the presence of tandem catalyst. This catalyst consisted of two components loaded in a layered manner: a copper–zinc oxide component responsible for the synthesis of methanol from CO2, and a zeolite component responsible for the conversion of methanol to liquid hydrocarbons. The structural effects of the zeolite component (Hybrid Intergrowth Structure Zeolites) on the yield and hydrocarbon composition of the liquid product were investigated. The textural properties of the zeolite component were found to be critical to the hydrocarbon composition of the liquid product. Hybrid co-crystalline structures, namely MFI–MEL and MFI–MCM-41, with their large volume of mesopores, significantly enhanced the content of aromatics in the liquid hydrocarbon product. This was achieved not only due to the reduced diffusion limitations for product removal from the zeolite pores but also due to the activation of secondary aromatization reactions in the catalyst mesopores.
