202 - Upscaling of a 500 kW Solar Powered Reactor for steam Gasification of Petroleum Coke

摘要

Hybrid solar/fossil endothermic processes, in which fossil fuels are used exclusively as the chemical source for H2 production and concentrated solar power is used exclusively as the energy source of process heat, offer a viable route for fossil fuel decarbonization and create a transition path towards solar hydrogen. Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form syngas. This process produces not only a highly useful and transportable end product, but also results in the storage of a significant fraction of solar energy in the chemical bonds of the fuel molecules.The steam-gasification of petroleum derivatives and residues using concentrated solar radiation is proposed as a viable alternative to solar hydrogen production. Therefore, PDVSA, CIEMAT and ETH started a joint project with the goal to develop and test a 500 kW plant for steam gasification of petcoke. This report summari zes the major accomplishments and challenges of upscaling the installation at the SSPS-tower of the Plataforma Solar de Almeria.
