Abstract: front page image
(EN)Provided are the preparation of a metal lattice-doping catalyst in an amorphous molten state, and the process of catalyzing methane to prepare olefins, aromatics, and hydrogen using the catalyst under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 750-1200 °C; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 1000-30000 ml/g/h; and fixed bed), the conversion of methane is 8-50%. The selectivity of olefins is 30-90%. And the selectivity of aromatics is 10-70%.
(FR)L'invention porte sur la préparation d'un catalyseur de dopage d'un réseau métallique à l'état fondu amorphe, et le procédé de catalyse du méthane pour préparer des oléfines, des aromatiques et de l'hydrogène par utilisation du catalyseur dans des conditions d'écoulement continu sans oxygène. Un tel procédé présente un faible dépôt de coke et réalise une conversion présentant une économie atomique. Dans les conditions rencontrées dans un réacteur à lit fixe (c'est-à-dire température de réaction : 750-1200 °C ; pression de réaction : pression atmosphérique ; vitesse spatiale horaire en poids du gaz de charge : 1000-30 000 ml/g/h ; et lit fixe), le taux de conversion du méthane est de 8-50 %. La sélectivité des oléfines est de 30-90 %. Et la sélectivité des aromatiques est de 10-70 %.
(ZH)The present invention is related to the preparation of a metal lattice-doping catalyst in an amorphous molten state, and the process of catalyzing methane to make olefins, aromatics, and hydrogen using the catalyst under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 750~1200 ℃; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 1000~30000 ml/g/h; and fixed bed), conversion of methane is 8-50%. The selectivity of olefins is 30~90%. And selectivity of aromatics is 10~70%. There is no coking. The reaction process has many advantages, including a long catalyst life (>100hrs), high stability of redox and hydrothermal properties under high temperature, high selectivity towards target products, zero coke deposition, easy separation of products, good reproducibility, safe and reliable operation, etc., all of which are very desirable for industrial application.
