[PMID: 38638568 PMCID: PMC11024928 DOI: 10.1016/j.isci.2024.109621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 02/09/2024] [Accepted: 03/26/2024] [Indexed: 04/20/2024] Open
Abstract
Light olefins are key intermediates in the synthesis of petrochemicals, and the conversion of stabilized carbon dioxide to light olefins using catalysts containing halogenated elements such as chlorine is a major challenge. Building on previous reports emphasizing the toxic effects of halogen elements on catalysts, we present the synthesis of FeMnKBr/YNa catalysts. This involved the synthesis of the catalyst by melt permeation using Br-containing potassium salts, other metal nitrates and YNa zeolites. The catalyst performed well in converting syngas (H2/CO2 = 3) to light olefins with a selectivity of 56.2%, CO2 conversion of 34.4%, and CO selectivity of 13.6%. Adding Br aids in reducing the Fe phase, boosts catalyst carburization, and produces more iron carbide species. It also moderately deposits carbon on the active center's surface, enhancing active phase dispersion. Br's electronegativity mitigates the influence of K, reducing catalyst's carbon-carbon coupling ability, leading to more low-carbon olefins generation.

Abstract
Light olefins (C2=-C4=) are important basic raw materials in chemical industries. Direct production of light olefins from syngas using zeolite encapsulation catalysts shows great potential due to their regulation of product distribution in the Fischer-Tropsch process. Herein, we report a series of silicalite-1 zeolite-encapsulated FeMnK catalysts with distinct nanostructures, including FeMnK@S-1, FeMnK@Hol-S-1, and FeMnK@HM-S-1. It was found that the FeMnK@HM-S-1 catalyst (encapsulation of FeMnK oxide in hollow mesoporous silicalite-1 crystal) had an enhanced C2=-C4= selectivity of 49% at a CO conversion of 12%. Our results revealed that superior light olefins selectivity of the FeMnK@HM-S-1 catalyst was achieved by the synergic effect between the inherent silicalite-1 micropores and the hollow mesoporous structure, which is responsible for restricting heavy hydrocarbon (C5+) formation, maximizing C2-C4 hydrocarbons selectivity, quickly removing the primary light olefin products, and increasing the O/P ratio. We demonstrated that the enhanced CO adsorption and the declined H2 adsorption (lower [H*]/[C*] ratio) over the FeMnK@HM-S-1 catalyst could also facilitate the olefin synthesis. This work provides guidance for reasonable designing of F-T catalysts to tailor product selectivity.
