“…A significant body of literature exists illustrating the advantages of thermochemical multifunctional catalysis (i.e., the combination of a metal/metal oxide and a zeolite as a multifunctional catalyst) for the hydrogenation of CO 2 to useful products. − Chief among the advantages is the sheer tunability of the product distribution that can be achieved by choosing the appropriate components of the multifunctional catalyst. This has repeatedly been demonstrated in the literature with products ranging from light olefins − to aromatics − and paraffins − being obtained by employing complementary configurations of a multifunctional catalyst.…”

The production of carbon-neutral fuels from CO2 presents an avenue for causing an appreciable effect in terms of volume toward the mitigation of global carbon emissions. To that end, the production of isoparaffin-rich fuels is highly desirable. Here, we demonstrate the potential of a multifunctional catalyst combination, consisting of a methanol producer (InCo) and a Zn-modified zeolite beta, which produces a mostly isoparaffinic hydrocarbon mixture from CO2 (up to ∼85% isoparaffin selectivity among hydrocarbons) at a CO2 conversion of >15%. The catalyst combination was thoroughly characterized via an extensive complement of techniques. Specifically, operando X-ray absorption spectroscopy (XAS) reveals that Zn (which plays a crucial role of providing a hydrogenating function, improving the stability of the overall catalyst combination and isomerization performance) is likely present in the form of Zn6O6 clusters within the zeolite component, in contrast to previously reported estimations.

“…65%) 25 , or propane (ca. 70%) 26 was achieved for the CO 2 hydrogenation. Nonetheless, it is very challenging to achieve a high selectivity to a defined hydrocarbon (in particular a relatively long chain one) through the CO 2 hydrogenation, due to the chemical inertia of CO 2 and the complexity of C–C coupling reactions.…”

Selective conversion of CO2 to isobutane-enriched C4 alkanes over InZrOx-Beta composite catalyst

et al. 2023

Direct conversion of CO2 to a single specific hydrocarbon with high selectivity is extremely attractive but very challenging. Herein, by employing an InZrOx-Beta composite catalyst in the CO2 hydrogenation, a high selectivity of 53.4% to butane is achieved in hydrocarbons (CO free) under 315 °C and 3.0 MPa, at a CO2 conversion of 20.4%. Various characterizations and DFT calculation reveal that the generation of methanol-related intermediates by CO2 hydrogenation is closely related to the surface oxygen vacancies of InZrOx, which can be tuned through modulating the preparation methods. In contrast, the three-dimensional 12-ring channels of H-Beta conduces to forming higher methylbenzenes and methylnaphthalenes containing isopropyl side-chain, which favors the transformation of methanol-related intermediates to butane through alkyl side-chain elimination and subsequent methylation and hydrogenation. Moreover, the catalytic stability of InZrOx-Beta in the CO2 hydrogenation is considerably improved by a surface silica protection strategy which can effectively inhibit the indium migration.

“…And in the residential sector, propane is widely used for air conditioning, heating, refrigeration, production of textiles, lighting, and other uses. However, despite the obvious importance of this hydrocarbon, propane formation from CO 2 has been barely touched in the available literature, , and only a few prior papers targeted paraffin formation, mostly from syngas. − …”

The production of carbon-rich hydrocarbons via CO 2 valorization is essential for the transition to renewable, non-fossil-fuel-based energy sources. However, most of the recent works in the state of the art are devoted to the formation of olefins and aromatics, ignoring the rest of the hydrocarbon commodities that, like propane, are essential to our economy. Hence, in this work, we have developed a highly active and selective PdZn/ZrO 2 +SAPO-34 multifunctional catalyst for the direct conversion of CO 2 to propane. Our multifunctional system displays a total selectivity to propane higher than 50% (with 20% CO, 6% C 1 , 13% C 2 , 10% C 4 , and 1% C 5 ) and a CO 2 conversion close to 40% at 350 °C, 50 bar, and 1500 mL g –1 h –1 . We attribute these results to the synergy between the intimately mixed PdZn/ZrO 2 and SAPO-34 components that shifts the overall reaction equilibrium, boosting CO 2 conversion and minimizing CO selectivity. Comparison to a PdZn/ZrO 2 +ZSM-5 system showed that propane selectivity is further boosted by the topology of SAPO-34. The presence of Pd in the catalyst drives paraffin production via hydrogenation, with more than 99.9% of the products being saturated hydrocarbons, offering very important advantages for the purification of the products.
