Abstract

The method involves supplying main fuel i.e. hydrocarbon based fuel, and additional fuel i.e. additional gas (11), which is obtained by reacting carbon dioxide from combustion of main fuel with a portion of main fuel on a catalytic mass i.e. dry reforming catalyst (10), heated inside a boiler by a burner (3), to the burner. The carbon dioxide obtained from burnt gas is concentrated on a membranous separator (6) that is made of ceramic, aluminosilicate, metal, plasma deposited metal, metal alloy or polymer organic material i.e. polyaramid. The catalyst is chosen from a group comprising nickel-based catalyst, iron-based catalyst or nickel-alumina-Yttria-stabilized zirconia based catalyst. An independent claim is also included for a device for operating a burner of a boiler.

Description

On sait que le chauffage domestique est en grande partie effectué à l'aide de chaudières dont le combustible est le gaz naturel composé en majorité de Méthane, et dont le diméthyle sulfure en très petite quantité, lui donne son odeur particulière. Les gaz de combustion résultants chauds contiennent principalement du dioxyde de carbone, de la vapeur d'eau, de l'azote, une certaine quantité d'oxyde de carbone suivant le réglage de la combustion, ainsi qu'une petite quantité de dérivés soufrés plus ou moins oxydés. It is known that domestic heating is largely carried out using boilers whose fuel is natural gas composed mainly of methane, and of which dimethyl sulphide in very small quantities, gives it its particular odor. The resulting hot flue gases mainly contain carbon dioxide, water vapor, nitrogen, some carbon monoxide depending on the combustion setting, and a small amount of sulfur derivatives more or less oxidized.

L'objet de la présente invention est de proposer un procédé et un dispositif permettant de valoriser une partie du dioxyde de carbone habituellement rejeté dans les gaz chauds à l'atmosphère, en le convertissant en combustible sous forme d'un mélange d'oxyde de carbone et d'hydrogène, en le faisant passer sur un catalyseur avec une partie du CH4 contenu dans le combustible de départ. Le combustible de départ sera préalablement débarrassé des dérivés soufrés qu'il contient par passage sur un adsorbant pouvant être un carbone activé, un tamis moléculaire ou une zéolithe, afin de ne pas empoisonner le catalyseur de conversion. Afin de ne pas recirculer des quantités de gaz non réactifs et pour faire réagir un mélange plus riche en CO2 avec le méthane, les gaz de sortie de la chaudière seront passés a travers un système membranaire capable de concentrer le CO2 contenu dans lesdits gaz. The object of the present invention is to provide a method and a device for recovering a part of the carbon dioxide usually released into the hot gases in the atmosphere, by converting it into a fuel in the form of a mixture of carbon and hydrogen, passing it over a catalyst with a portion of the CH4 contained in the starting fuel. The starting fuel will be previously free of sulfur derivatives it contains by passing on an adsorbent may be an activated carbon, a molecular sieve or a zeolite, so as not to poison the conversion catalyst. In order not to recirculate quantities of nonreactive gases and to react a richer CO2 mixture with methane, the boiler outlet gases will be passed through a membrane system capable of concentrating the CO2 contained in said gases.

Le séparateur de dioxyde de carbone peut être d'un type quelconque, pourvu qu'il soit adapté à la température des gaz qui le traversent . On pourra utiliser un séparateur en céramique, en aluminosilicate, en métal ou en alliage de métaux nobles. On pourra aussi utiliser des séparateurs à membrane polymère fonctionnant à des températures ne dépassant pas 200°, à condition toutefois de refroidir la sortie des gaz. The carbon dioxide separator can be of any type, provided that it is adapted to the temperature of the gases passing through it. A ceramic, aluminosilicate, metal or noble metal alloy separator may be used. It will also be possible to use polymer membrane separators operating at temperatures not exceeding 200 °, provided however that the gas outlet is cooled.

La conversion du CO2 issu du séparateur membranaire s'effectue en présence d'une partie du méthane contenu dans le gaz de départ. La quantité de méthane injectée peut être en excès puisque l'ensemble retourne au brûleur. L'excès de réactif oriente la réaction dans le sens recherché, et le méthane n'ayant pas réagi va au bruleur. La réaction qui a lieu au niveau du catalyseur peut être représentée par l'équation générale: CO2 + CH4 = 2 CO +2H2 delta H°298 K =247.9 kj/mol - et la cinétique de la réaction évolue positivement avecle départ des réactifs produit dans la zone de réaction. L'oxydation partielle du carbone du CH4 est inclue comme étape déterminante de cette réaction de reformage et offre l'avantage de conserver un rapport H2/CO élevé, proche de 2, tout en impliquant un procédé quasi athermique, c'est-à-dire ne produisant pas ni ne consommant pas d'énergie calorifique. The conversion of CO2 from the membrane separator takes place in the presence of a portion of the methane contained in the starting gas. The amount of methane injected may be in excess since the assembly returns to the burner. Excess reagent directs the reaction in the desired direction, and the unreacted methane goes to the burner. The reaction which takes place at the level of the catalyst can be represented by the general equation: CO2 + CH4 = 2 CO + 2H2 delta H ° 298 K = 247.9 kJ / mol - and the kinetics of the reaction evolves positively with the departure of the reagents in the reaction zone. The partial oxidation of CH4 carbon is included as a decisive step in this reforming reaction and offers the advantage of maintaining a high H2 / CO ratio close to 2, while involving a quasi-athermic process, i.e. ie not producing or consuming heat energy.

Le catalyseur de conversion du mélange CO2 + METHANE.est un catalyseur classique de reforming à base de nickel ou de fer. La température de fonctionnement de celui-ci est comprise entre 450° à 800°, pouvant être réglée plus ou moins par une disposition judicieuse de la place de la cuve de catalyseur dans le parcours de la flamme du brûleur. The conversion catalyst of the CO 2 + METHANE mixture is a conventional reforming catalyst based on nickel or iron. The operating temperature thereof is between 450 ° and 800 °, which can be adjusted more or less by a judicious arrangement of the position of the catalyst vessel in the path of the burner flame.

Il convient de noter que les gaz brulés à la sortie de la chaudière renferment en outre du CO2, du N2, de la vapeur d'eau et un peu de CO: cela ne constitue généralement pas un inconvénient et la vapeur d'eau peut même être utile comme réactif dans le convertisseur catalytique. It should be noted that the gases burned at the outlet of the boiler also contain CO2, N2, water vapor and some CO: this is not generally a disadvantage and the water vapor can even be useful as a reagent in the catalytic converter.

L'invention concerne entre autres un dispositif de production d'énergie calorifique comprenant un brûleur alimenté en gaz principal et un autre combustible additionnel provenant de la sortie du catalyseur, pour fournir des calories et à nouveau du CO2, de l'azote, de l'eau. The invention relates, inter alia, to a heat energy production device comprising a burner fed with main gas and another additional fuel coming from the outlet of the catalyst, for supplying calories and again CO2, nitrogen, water, and 'water.

L'invention concerne un dispositif d'élimination des dérivés soufrés que contient le gaz de départ et qui sont des poisons pour les catalyseurs de conversion. Cet absorbeur est rempli d'un carbone activé à grande surface spécifique, supérieure a 1500, sous forme de grains ou de tout autre absorbant capable de retenir le mercaptant qui donne l'odeur au gaz de départ: le tout est logé dans une enveloppe métallique dont le volume est calculé pour donner un temps de contact du gaz suffisant avec l'absorbant. The invention relates to a device for removing sulfur derivatives contained in the starting gas and which are poisons for conversion catalysts. This absorber is filled with a high surface area activated carbon, greater than 1500, in the form of grains or any other absorbent capable of retaining the mercaptant which gives the odor to the starting gas: the whole is housed in a metal casing whose volume is calculated to give a sufficient gas contact time with the absorbent.

L'invention est illustrée a titre d'exemple par la figure n°1: ù Entrée du gaz 1 Purification du gaz 2 Brûleur du ou des gaz 3 Sortie des gaz brulés 5 Membrane séparatrice 6 - Sortie du CO2 concentré 7 Mélange avec gaz de départ 8 Passage sur catalyseur 10 Sortie du nouveau gaz 11 Alimentation au bruleur principal ou brûleur dédié 3 ù Sortie des gaz brûlés 5 Rejet à l'atmosphère des gaz appauvris en CO2 12 Le procédé et dispositif de l'invention sont dèstiné à traiter une partie du CO2 contenu dans les gaz brûlés en réutilisant le CO2 produit lors de la combustion du gaz, et en transformant celui-ci à nouveau en gaz combustible à l'aide du gaz de départ Cela conduit à une économie de carbone de départ et contribue à diminuer la masse de CO2 participant à l'effet de serre. The invention is illustrated by way of example in FIG. 1: ù Gas inlet 1 Gas purification 2 Burner of the gas (s) 3 Exit of the burned gases 5 Separating membrane 6 - Concentrated CO2 outlet 7 Mixing with gas starting 8 Catalyst passage 10 New gas outlet 11 Supply to the main burner or dedicated burner 3 - Exit of flue gas 5 Release of CO 2 depleted gases to the atmosphere 12 The method and apparatus of the invention are designed to process a portion of the CO2 contained in the flue gases by reusing the CO2 produced during the combustion of the gas, and transforming it back into fuel gas using the starting gas This leads to a carbon saving and helps to reduce the CO2 mass involved in the greenhouse effect.

Procédé et dispositif de l'invention applicable aux chaudières domestiques de faible puissance et industrielles fonctionnant au gaz naturel ou de synthèse apportant une économie sur le combustible principal pouvant aller de 20 à 40 % en fonction du CO2 extrait par le système membranaire à la sortie des gaz brulés. 3 Process and device of the invention applicable to domestic low-power and industrial boilers operating on natural gas or synthesis, providing savings on the main fuel of between 20 and 40% depending on the CO2 extracted by the membrane system at the outlet of burned gas. 3
