Title
(EN) METHOD FOR DIRECT METHANE PYROLYSIS
(FR) PROCEDE DE PYROLYSE DIRECTE DU METHANE
Abstract
(EN)
The invention makes it possible to increase the ethylene content in reaction products during direct conversion of methane. The invention is characterized by the fact that pyrolysed natural gas is pre-heated to 900-1000 K and the conversion process is performed in two steps. In the first step, gas is heated to 1800-2100 K during 1-2 msec, and in the second step the heated mixture of the primary reaction products is conditioned at a pressure ranging from 2 to 5 MPa in an adiabatic state during 5-10 msec. In addition, the reaction products are tempered. Said range of temperatures at the first step of the conversion process is maintained by an outside energy supply. The inventive method makes it possible to perform the direct methane conversion process and obtain an ethylene content of 67.4 % and an acetylene content of 9.1 % in pyrolyzates. The degree of the direct methane conversion is equal to 88.1 %.

L'invention permet d'augmenter la teneur de produits de réaction en éthylène lors de la conversion directe de méthane. Selon l'invention, on chauffe du gaz naturel à pyrolyser préalablement à 900-1000 K, et l'on effectue la conversion du méthane en deux stades. Au premier stade, on chauffe le gaz à 1800-2100 K pendant 1 à 2 msec; au second stade, le mélange chauffé des produits de la réaction primaire est soumis à une pression entre 2 et 5 MPa en régime adiabatique pendant 5 à 10 msec. On procède ensuite au recuit des produits de réaction. Au premier stade de conversion du méthane, on entretien l'intervalle de températures indiqué ci-dessus grâce à l'apport de l'énergie depuis l'extérieur. Les essais du procédé ont permis d'effectuer une conversion directe du méthane et d'obtenir dans les produits de pyrolyse de l'éthylène 67,4 % d'éthylène et 9,1 % d'acétylène. Le taux de conversion du méthane s'élève à 88,1 %.
