“…Comparing the results with those obtained with the most alike catalysts available in the literature, the olefin yield is consistent with the results reported by Dang et al . (at 380 °C, 30 bar) and by Numpilai et al (at 360 °C, 25 bar) with H 2 /CO 2 /N 2 feedstocks. In other works, a higher space time is required to reach the same value of light olefin yield.…”

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 gcatalyst h molC –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 x conversions, yield and selectivity of olefins and paraffins, and stability), the following have been established as suitable conditions: 400 °C, 30 bar, 5–10 gcat h molC –1, CO2/CO x = 0.5, and H2/CO x = 3. Under these conditions, the catalyst is stable (after an initial period of deactivation by coke), and olefin yield and selectivity surpass 4 and 70%, respectively, with light paraffins as byproducts. Produced olefin yields follow propylene > ethylene > butenes. The conditions of the process (low pressure and low H2/CO x ratio) may facilitate the integration of sustainable H2 production with PEM electrolyzers and the covalorization of CO2 and syngas obtained from biomass.

“…235 The majority of papers have addressed SAPO-34 as a zeolite component for LO synthesis via the methanol-mediated route. 408,[419][420][421][422] Wang 396 et al provided the analysis of SAPO type effect on the selectivity of CO 2 hydrogenation and showed that SAPO-34 possessed the highest one towards LO fraction. At the same time, DFT calculations and catalytic experiments showed that SAPO-18 significantly enhanced the olefin-to-paraffin ratio in CO hydrogenation compared to SAPO-34 due to the suppression of hydride transfer.…”

“…[150,151] SAPO-34, in combination with other metal and metal-oxide catalysts, is considered to be an efficient catalyst for CO 2 conversion into value-added products. [152] The catalytic route for CO 2 conversion into HCs involves two major approaches: combined conventional Fischer Tropsch synthesis (FTS) and reverse water gas shift (RWGS). [153,154] Using this approach, the RWGS reaction process generates CO from the CO 2 hydrogenation (Eq.…”

Among several known zeolites, silicoaluminophosphate (SAPO)‐34 zeolite exhibits a distinct chemical structure, unique pore size distribution, and chemical, thermal, and ion exchange capabilities, which have recently attracted considerable research attention. Global carbon dioxide (CO2) emissions are a serious environmental issue. Current atmospheric CO2 level exceeds 414 parts per million (ppm), which greatly influences humans, fauna, flora, and the ecosystem as a whole. Zeolites play a vital role in CO2 removal, recycling, and utilization. This review summarizes the properties of the SAPO‐34 zeolite and its role in CO2 capture and separation from air and natural gas. In addition, due to their high thermal stability and catalytic nature, CO2 conversions into valuable products over single metal, bi‐metallic, and tri‐metallic catalysts and their oxides supported on SAPO‐34 were also summarized. Considering these accomplishments, substantial problems related to SAPO‐34 are discussed, and future recommendations are offered in detail to predict how SAPO‐34 could be employed for greenhouse gas mitigation.
