Title: Exploring low-temperature dehydrogenation at ionic Cu sites in beta zeolite to enable alkane recycle in dimethyl ether homologation

Abstract

Cu-based catalysts containing targeted functionalities including metallic Cu, oxidized Cu, ionic Cu, and Bronsted acid sites were synthesized and evaluated for isobutane dehydrogenation. Hydrogen productivities, combined with operando X-ray absorption spectroscopy, indicated that Cu(I) sites in Cu/BEA catalysts activate C-H bonds in isobutane. Computational analysis revealed that isobutane dehydrogenation at a Cu(I) site proceeds through a two-step mechanism with a maximum energy barrier of 159 kJ/mol. Furthermore, these results demonstrate that light alkanes can be reactivated on Cu/BEA, which may enable re-entry of these species into the chain-growth cycle of dimethyl ether homologation, thereby increasing gasoline-range (C₅₊) hydrocarbon yield.

Shifting the Paraffin-to-Olefin Ratio and Gasoline Fuel Properties with Bimetallic BEA Zeolite Catalysts in Dimethyl Ether Homologation

Conference Nash, Connor P ; Dupuis, Daniel P ; Farberow, Carrie A ; ...

Recent research on the production of HOG from DME over BEA zeolites suggests that this process offers an attractive alternative to traditional methanol-to-gasoline (MTG) technologies by operating at milder conditions and providing greater carbon efficiency 1. The HOG product is rich in branched olefins and paraffins, particularly triptane (2,2,3-trimethylbutane) which has high research- and motor-octane numbers (RON 112, MON 101), making it an ideal unleaded fuel or fuel additive for aviation or racing applications 2. RON and MON are important fuel metrics and research shows a correlation between them and paraffin and olefin content 3. Copper-modified BEA (Cu/BEA) is moremore »« less

A separations and purification process for improving yields and meeting fuel contaminant specifications for high-octane gasoline produced from dimethyl-ether over a Cu/BEA catalyst

Abstract We have been developing a three‐step conversion of biomass‐derived syngas to methanol to dimethyl‐ether (DME) to non‐aromatic hydrocarbons for use as high‐octane gasoline and sustainable aviation fuel. This process produces branched alkanes from DME using a Cu/BEA catalyst and is a promising alternative to other syngas conversion processes such as Fischer–Tropsch to linear alkanes and traditional ZSM‐5 catalyzed methanol to aromatic gasoline. In this short article we describe some advances in our understanding related to separation and purification via the use of more detailed experimental speciation in an updated process model involving multiple‐phase equilibrium‐based separation steps.

Connecting cation site location to alkane dehydrogenation activity in Ni/BEA catalysts

Journal Article Farberow, Carrie A ; Wegener, Evan C. ; Kumar, Anurag ; ... - Journal of Catalysis

Ni-modified beta zeolite (Ni/BEA) catalysts activate carbon-hydrogen bonds in light alkanes, as demonstrated through isobutane reaction testing. Controlled synthesis of Ni/BEA allows for efficient introduction of ion-exchanged Ni sites at varying Ni loadings (0.43% - 1.8%). These catalysts exhibit site time yields (STY) for H2 production that increase with increasing Ni loading. A detailed analysis of secondary reactions and carbon deposition based on the relative molar flowrates of product C and H indicates that the observed increase in H2 STY with increasing Ni loading is likely attributed to both increasing alkane activation activity and increasing formation of hydrogen-deficient aromatic productsmore »« less

Catalyst design to direct high-octane gasoline fuel properties for improved engine efficiency

Journal Article Nash, Connor P. ; Dupuis, Daniel ; Kumar, Anurag ; ... - Applied Catalysis. B, Environmental

The paraffin-to-olefin (P/O) ratio in gasoline fuel is a critical metric affecting fuel properties and engine efficiency. In the conversion of dimethyl ether (DME) to high-octane hydrocarbons over BEA zeolite catalysts, the P/O ratio can be controlled through catalyst design. Here, we report bimetallic catalysts that balance the net hydrogenation and dehydrogenation activity during DME homologation. The Cu-Zn/BEA catalyst exhibited greater relative dehydrogenation activity attributed to higher ionic site density, resulting in a lower P/O ratio (6.6) versus the benchmark Cu/BEA (9.4). The Cu-Ni/BEA catalyst exhibited increased hydrogenation due to reduced Ni species, resulting in a higher P/O ratio (19).more »« less
