Description
The production of sustainable transportation fuels has become a priority for continued human prosperity. While hydrogen holds much promise, several issues remain to make it a viable option. Production of hydrocarbon fuels from CO2 using electrical energy has the potential for carbon neutral products that can be used in the existing transportation infrastructure with minimal modifications. This paper will describe initial bench-scale testing of an electrochemical system designed to generate CO and synthesis gas (H2 + CO) mixtures. The system was constructed and operated to develop data for determining feasibility and uncover potential technical issues prior to pilot-scale design. To overcome mass-transport limitations imposed by limited CO2 solubility, silver loaded gas diffusion electrodes (GDE) were incorporated into a commercial type flow cell. Gaseous products collected from the headspace of the cathode solution were analyzed using gas chromatography. Process variables examined during the initial phase of testing will be presented. Technical challenges and potential for commercial-scale implementation will be discussed.
