Descripción del proyecto
Conversión de CO2 en ingredientes para combustibles y plásticos
El gas de efecto invernadero CO2 podría captarse de los flujos de residuos industriales y convertirse en una materia prima valiosa. Actualmente, su transformación se ve obstaculizada por el pobre rendimiento de CO2-a-producto. El proyecto COZMOS, financiado con fondos europeos, superará este problema combinando dos reacciones en un reactor con el fin de incrementar la tasa de conversión de CO2 y reducir el consumo de energía. La transformación del CO2 procedente de fuentes de energía renovables dará lugar a la producción de propano (un combustible que se puede almacenar fácilmente para su uso en calefacción, cocinas y transporte) o propileno, que constituye la base de los plásticos ligeros. La tecnología de COZMOS contribuirá a la economía circular y a la sustitución de los combustibles fósiles, lo cual dará lugar a una disminución de las emisiones de CO2 y reducirá la dependencia europea de los recursos basados en combustibles fósiles.
Objetivo
"What if we were able to use CO2 and H2 from renewable energy sources as fuel and chemical feedstocks, and thus decrease CO2 emissions and displace fossil fuels at the same time? COZMOS will develop an energy-efficient and environmentally and economically viable conversion of CO2 to fuels and high added value chemicals via an innovative, cost effective catalyst, reactor and process. The concept will combine the sequential reactions of CO2 hydrogenation to methanol and methanol to C3 hydrocarbons, exploiting Le Chatelier's principle to overcome low equilibrium product yields of methanol. Complete conversion of CO2 to a 85 % yield of C3 hydrocarbons will be achieved by using an optimised bifunctional catalyst within a single reactor. The optimised catalyst will allow the combined reactions, that currently run at disparate temperatures and pressures, to operate in a temperature/pressure ""sweet spot"", which will reduce infrastructure and provide energy and production cost savings. The concept will allow tunable production of propane, an easily stored fuel used for heating, cooking and transportation, and the more valuable product propene, a base chemical primarily polymerised to lightweight plastics, depending on location, amount of available renewable energy and economic needs. The integrated technology will be demonstrated at TRL5 on off-gases from the energy intensive steel and refinery industries. Markets for both propane and propene are expected to grow in the coming years, such that the COZMOS technology will contribute to achieving a Circular Economy and diversified economic base in carbon-intensive regions.
Throughout the whole value chain development, emphasis will be placed on risk-mitigation pathways and strong industrial involvement, LCA and techno-economic analysis to maximise further exploitation and industrialisation of the results. Specific attention will be paid to social acceptance, including analysis of stakeholder and end-user interests."
