Embodiment Construction

[0046] The carbonization reaction, that is, the CO in the flue gas according to the following reaction equation 2 and a sorbent material such as selected from metal oxides (MeO) to form MeCO 3 Reaction:

[0047] MeO + CO 2 →MeCO 3 + heat

[0048] The reaction is exothermic and proceeds at a temperature depending on the metal oxide used. Control of temperature is important to ensure an efficient reaction system that balances kinetic and equilibrium requirements. Carbon dioxide CO can occur using different metal oxides MeO that form metal carbonates such as limestone 2 catch. Metal oxides can also be part of synthetic solid particles. The metal oxide used in the present invention can be selected from calcium oxide CaO, magnesium oxide MgO, aluminum oxide Al 2 o 3 , zinc oxide ZnO and calcium magnesium oxide CaMgO, which form calcium carbonate (CaCO 3 ) (for example in the form of calcite or aragonite), magnesium carbonate (MgCO 3 ) (for example in the form of magnesi...

Abstract

The present invention relates to a process for the capture of carbon dioxide CO2 by carbonization in a circulating fluidized bed (CFB) carbonization reactor (10) by recycling the solid fractions of metal oxide MeO and metal carbonate MeCO3 to the CFB The carbonization reactor (10) adjusts the temperature distribution. The present invention also provides a system (1) for recycling metal oxide MeO and metal carbonate MeCO3.

Description

[0001] field of invention [0002] The invention relates to a carbonization reaction for capturing carbon dioxide CO 2 method, which involves recirculating the cooled MeCO 3 Enriched solids stream. In addition, the present invention relates to a system comprising a 2 Enriched flue gas captures carbon dioxide CO 2 of the reactor. [0003] Background of the invention [0004] Carbon dioxide capture can be implemented by carbonization reaction in a circulating fluidized bed (CFB) using solids of metal or mineral oxides 2 . Metal or mineral oxides used as carbon dioxide CO 2 The absorbent is a solid sorbent. [0005] The reactions that take place in the CFB carbonization reactor are exothermic, where the reaction rate depends largely on the available surface of the solid sorbent. In addition, in order to meet the reaction kinetics and equilibrium requirements of the absorption process, precise control of the temperature distribution is required. Therefore, reactor optimiza...
