Definitions

  • the invention relates to a chemical process for regenerating a catalyst, in particular a catalyst for catalytic cracking processes, by burning coke from its surface, as well as obtaining thermal energy for its subsequent beneficial use, while simultaneously capturing/recovering carbon dioxide for subsequent transportation to storage sites and reducing emissions greenhouse gases into the atmosphere.
  • the closest analogue is the method of fuel combustion with subsequent capture of carbon dioxide US2009075219 (A1), published on March 19, 2009.
  • the method includes supplying an oxygen flow to the combustion chamber with subsequent condensation of water vapor, releasing part of the flue gases into the atmosphere and part of the flue gases to the capture process carbon.
  • the disadvantage of this method is the inability to regulate the concentrations of components in the flue gas flow for oxygen in the concentration range from 1% vol. up to 50% vol., for carbon dioxide from 1% vol. up to 50% vol., nitrogen concentration no more than 30% vol., as well as the need for condensation of water vapor, which is ensured by reducing the temperature of the flue gases to 15 °C, which in turn requires significant operating costs for cooling.
  • the patent also does not include the recirculation of the flue gas flow back into the combustion process zone of hydrocarbon gas, hydrocarbon liquid, oil residues and the recirculation of the carbon dioxide and nitrogen flow after the carbon capture process in order to regulate the concentration of components in the combustion zone.

Abstract

L'invention concerne un processus chimique de régénération de catalyseur, notamment de catalyseur pour les processus de craquage catalytique. L'invention concerne un procédé de régénération de catalyseur par carbonisation de coke, lequel comprend la séquence d'actions suivante: a) concentrer l'oxygène de l'air; b) régénérer le catalyseur par carbonisation du coke dans un mélange d'un flux de recyclage des gaz de fumée formés lors du processus de combustion, d'un flux de recyclage de dioxyde de carbone et d'azote, d'un flux d'oxygène et d'un flux d'air atmosphérique; c) évacuer les gaz de fumée de la zone de régénération du catalyseur à l'aide d'un extracteur de fumée et/ou d'un compresseur avec un recyclage partiel des gaz dans la zone de combustion; d) envoyer la quantité résiduelle de gaz de fumée vers un processus d'extraction de dioxyde de carbone en vue de leur envoi subséquent vers un stockage et de la séparation de l'eau condensée; e) recycler le dioxyde de carbone dans la zone de régénération du catalyseur. L'invention permet de réduire les dépenses fonctionnelles pour un processus de piégeage de dioxyde de carbone, et de réduire les rejets de gaz à effet de serre dans l'atmosphère.
