Thermochemical process of concentrated solar energy storage from steel slag (Machine-translation by Google Translate, not legally binding)

摘要

The present invention proposes the use of pre-treated steel slag for the thermochemical storage of concentrated solar energy (csp) by integrating this technology with the "calcium looping" (cal) process. Steel mill slag is a low cost, abundant and non-toxic material. The cao derived from the treatment of the slag with acetic acid has a high and stable value of its conversion in caco3 throughout successive cycles of carbonation/calcination carried out under conditions of maximum efficiency for the csp-cal integration. The invention has application in the energy sector, and in particular, in the area of renewable energies. It is also relevant in the metallurgical sector because it revalues the steel slag for use in energy storage. (Machine-translation by Google Translate, not legally binding)
