Background

This project aims to design and demonstrate a core-shell structured multifunctional catalyst for single step conversion of the light components of shale gas into liquid aromatic compounds. Operated in a modular oxidative aromatization system (OAS) under a cyclic redox scheme, the novel catalyst and process can significantly improve the value and transportability of stranded natural gas.

Impact

It is anticipated that the Oxidative Aromatization System (OAS) will produce high-value liquid aromatics from low-value natural gas: converting flared and rejected methane (C1) and ethane (C2) alone may lead to a >$5 billion/year value creation. Successful completion of the project will result in optimized OAS redox catalysts with superior aromatics yield (>40% per-pass or 90% overall) and stability (<5% deactivation over 100 hours redox cycles). Realization of these goals will significantly de-risk the scale up and commercialization efforts related to the technology.

Accomplishments (most recent listed first)
  • Selective Hydrocarbon Combustion (SHC) screening - Seven catalysts screened, four showed satisfactory H2 combustion selectivity (>80%), one showed >200 mol/kgCat-hr activity at 0.1 atm PH2. All four are expected to exceed this activity at >0.5 atm PH2 (based on a reaction order of 1).
  • Dehydoaromatization Screening (DHA) Catalyst Screening - 3 or more DHA catalysts screened with > 500 g/kgCat-hr aromatics productivity and > 80% selectivity at <700 °C.
