Descripción del proyecto
El biocarbón puede hacer que las plantas de laminación de acero sean más ecológicas
Las plantas de laminación de acero y las metalúrgicas suponen un reto importante para alcanzar la neutralidad en emisiones de carbono. El equipo del proyecto H2STEEL, financiado con fondos europeos, espera ofrecer una solución convirtiendo los residuos biológicos y el biometano en hidrógeno verde, carbono y materias primas fundamentales mediante un nuevo tipo de pirólisis catalizada. Mediante un reactor de nuevo diseño que emplea un novedoso catalizador, el biometano puede convertirse en hidrógeno verde de forma económica. Los materiales derivados pueden utilizarse en los procesos de fabricación de acero. Esta solución innovadora evita la emisión de CO2 y supone una reducción neta de los gases de efecto invernadero.
Objetivo
The achievement of the Net-zero emissions target established by the European Commission is huge challenge which could not be achieved without re-thinking the conventional route (materials and energy chains). H2STEEL project proposes an innovative, disruptive solution to convert wet waste streams into green Hydrogen, Carbon and Critical Raw Materials. The proposed innovative solution aims at supporting the green transition of one of the most hard-to-abate industrial sector: metallurgy. In particular, H2STEEL combines the conversion of biowaste and bioCH4 through innovative catalyzed pyrolysis with chemical leaching, to fully convert biowastes into Green Hydrogen, Green Carbon (biocoal), and recovery of Critical (inorganic) Raw Materials. Biomethane pyrolysis is carried out in a brand new, ad-hoc designed, and proof-of-concept reactor, on a bed of biocoal made from pre-carbonized biowastes, i.e. on a very cheap fully carbon-based catalyst, very resistant to temperature and contaminants: this will enhance the efficiency of the methane cracking step to generate Green Hydrogen. As new solid carbon from methane cracking is generated on the biocoal surface, thus reducing the performance of the catalyst, new biocoal-catalyst is inserted in the reactor, while the spent biocoal is removed: the continuous renewal of the catalyst is feasible thanks to its low cost, and to the market value of the spent catalyst. This material, fully bio-carbon based, is then used in steel-making as a substitute of metallurgical (fossil) coke, generating a net GHG reduction, EU ETS (Emission Trading Scheme) compliant. The regeneration of the spent catalyst thus becomes unnecessary, as the biocoal is used in a downstream process, avoiding the release of CO2 in atmosphere (as it happens in the SMR process or in most of the catalysts regeneration steps).
