Direct (fully-integrated) conversion in compact sized reactor
The eCOCO2 project will achieve overall conversion efficiencies higher than those observed in multi-step conversion technologies, and at the same time reach lower production costs. This will be achieved by reducing energy expenses (due to the higher energy efficiency) and capital investment (due to process intensification).
The eCOCO2 project will develop alternative technologies to produce carbon-neutral synthetic jet fuels from CO2 and water having a suitable composition of different types of C7-C16 hydrocarbons that include, besides linear and branched paraffins, cyclic paraffins and aromatics. These will be of high relevance for their direct use (i.e. without requiring blending with conventional oil-derived jet fuels) in aircraft engines. The integrated technologies will combine CO2 reduction and steam electrolysis in a one step process of unprecedented efficiency.
The eCOCO2 project will optimise multi-functional catalysts for the one-pot production of jet fuels (C7-C16) directly from CO2 and H2 by properly tuning the properties of both the first reduction steps catalyst and the zeolite (e.g. acidity, pore size, pore interconnectivity, crystallite size, etc.). Two routes involving (1) light olefins (via m-FTS), and (2) methanol/DME intermediates will be considered. The catalyst properties will be adjusted to enable the efficient operation in the conditions required for integration with co-ionic electrochemical cells.
The eCOCO2 project will validate and optimize a co-ionic membrane reactor based on PCEC technology for the direct electrocatalytic conversion of CO2 and steam into chemical energy carriers.
