  • the invention is aimed at capturing and sequestering C0 2 in ceramic materials from construction waste. These materials react directly with C0 2 in the presence of water producing carbonates, so that C0 2 is permanently stabilized.
  • the present invention has a double environmental application: on the one hand, there is a reduction in atmospheric C0 2 since it would be injected into ceramic waste from the construction and on the other, the negative landscape impact caused by the ceramic waste from the construction would be reduced .
  • C0 2 The capture and storage of C0 2 (CAC or CCS "carbon capture sequestration") is considered one of the options to reduce the emissions of C0 2 generated by human activities.
  • Other technological options are the following: 1) the reduction of energy demand by increasing the efficiency of energy conversion and / or use devices; 2) the decarbonisation of the energy supply (opting for fuels with less carbon, for example, replacing coal with natural gas), and / or increasing the use of renewable energy sources and / or nuclear energy (which, in definitively, they emit scarce amounts, if any, of C0 2 ); 3) the sequestration of C0 2 through the improvement of natural sinks through biological fixation; and 4) the reduction of greenhouse gases other than C0 2 .
  • the CAC or CCS (Carbon Capture and Storage) is probably the biggest geotechnological challenge of the 21st century.
  • the CAC first involves the use of technologies to collect and concentrate the C0 2 produced in industrial sources, then transport it to an appropriate storage location and then store it isolating it from the atmosphere for a long period of time.
  • geological formations and structures most conducive to the deep storage of C0 2 have been widely documented in the scientific and technical literature generated in recent years: 1) coal layers rich in methane, 2) depleted or depleted deposits of hydrocarbons (oil and gas), 3) deep saline aquifers, and 4) cavities in salt formations.
  • the first three types are postulated as more prominent objectives, although their presence and storage capacity, that is, their dimensions, are conditioned by the specific geological features of each territory.
  • Other possible formations or geological structures represent storage options that have not yet been studied enough to be able to assess their potential today.
  • the purpose of this invention is to propose the injection of C0 2 into quarries and gravels recovered with RDC. For it is part of laboratory experiments on ceramic materials and C0 2 in different environmental conditions. It has been shown that in the presence of water carbonation process is a direct flow of C0 2 at low pressure ( ⁇ 20 bar). Experiences have been carried out with CC1 ⁇ 2 in a supercritical state and it has been proven that the carbonation process has a lower yield.

  • these materials react directly with C0 2 producing carbonates, so that carbon dioxide is fixed permanently.
  • the presence of water is essential for such a carbonation reaction to occur in ceramic materials, the proportion of water having to vary between 5 and 30% by weight depending on the composition and manufacturing temperature of the structural ceramics.
  • These ceramic materials are manufactured from common clays in a temperature range of 800 ° C-1100 ° C.
  • These ceramic materials are injected with low pressure C0 2 (with an injection pressure of C0 2 varying between 0.5 and 80 bar, the highest yields at pressures of C0 2 ⁇ 20 bar) with which it reacts chemically always in the presence of water giving rise to carbonates, so it is permanently fixed.
  • reaction yield is higher at low pressures of C0 2, so it is not necessary to reach large pressures of C0 2 and therefore, to store at 800m depth as required by other C0 2 capture alternatives
  • the raw material is based on a mixture of common clays containing 30% carbonates (calcite and dolomite), 30% quartz, 37% phyllosilicates and 3% feldspars.

  • the content of calcite increases from 5% to more than 15% by weight, due to the carbonation produced after reacting the calcium present (obviously not in the form of calcite) with C0 2 in the presence of water.

Abstract

L'invention a pour objet la capture et la séquestration de CO2 dans des matériaux céramiques issus de résidus de la construction. Ces matériaux réagissent directement avec le CO2 en présence d'eau, produisant des carbonates, de sorte que le CO2 se stabilise de manière permanente. La présente invention présente une double application environnementale: d'une part, il se produit une réduction du CO2 atmosphérique étant donné qu'il est injecté dans des résidus céramiques issus de la construction et d'autre part, l'impact négatif sur le paysage causé par les résidus céramiques de la construction sont réduits.
