Conditions for the Joint Conversion of CO₂ and Syngas in the Direct Synthesis of Light Olefins Using In₂O₃-ZrO₂/SAPO-34 Catalyst.

ABSTRACT: The conditions for promoting the joint conversion of CO₂ and syngas in the direct synthesis of light olefins have been studied. In addition, given the relevance for the viability of the process, the stability of the In₂O₃-ZrO₂/SAPO-34 (InZr/S34) catalyst has also been pursued. The CO+CO₂ (CO _x ) hydrogenation experimental runs were conducted in a packed bed isothermal reactor under the following conditions: 375-425 °C; 20-40 bar; space time, 1.25-20 g_catalyst h mol_C ^-1; H₂/(CO _x ) ratio in the feed, 1-3; CO₂/(CO _x ) ratio in the feed, 0.5; time on stream (TOS), up to 24 h. Analyzing the reaction indices (CO₂ and CO
