Abstract:
(EN) A catalyst and a method for direct conversion of syngas to prepare light olefins. Using syngas as a raw material for reaction, a conversion reaction is conducted on a fixed bed or on a mobile bed. The catalyst is a composite catalyst A+B and is created by compounding together catalyst A and catalyst B by means of mechanical mixing. The active ingredient in catalyst A is active metal oxide, catalyst B is an oxide-loaded molecular sieve. The vector is one or two or more of hierarchical porous Al2O3, SiO2, TiO2, ZrO2, CeO2, MgO, and Ga2O3. The molecular sieve is one or two of a CHA structure and an AEI structure, the load capacity of the molecular sieve being 4%-45% wt. The weight ratio between the active ingredient in catalyst A and catalyst B is in the range of 0.1-20, and preferably 0.3-5. The reaction process has high light olefin selectivity, the sum of the selectivity of the light olefins comprising ethylene, propylene, and butene being as high as 50-90%. Additionally, the selectivity of the byproduct methane is lower than 15%. The invention has excellent prospects for application.
(FR) La présente invention concerne un catalyseur et un procédé de conversion directe de gaz de synthèse pour préparer des oléfines légères. À l'aide d'un gaz de synthèse utilisé en tant que matière première pour la réaction, une réaction de conversion est mise en œuvre sur un lit statique ou sur un lit mobile. Le catalyseur est un catalyseur composite A+B et est créé en mélangeant ensemble le catalyseur A et le catalyseur B par mélange mécanique. Le principe actif dans le catalyseur A est un oxyde métallique actif, le catalyseur B est un tamis moléculaire chargé d'oxyde. Le vecteur est un ou deux constituants ou plus parmi les éléments poreux hiérarchiques suivants : Al2O3, SiO2, TiO2, ZrO2, CeO2, MgO, et Ga2O3. Le tamis moléculaire est une structure CHA et/ou une structure AEI, la capacité de charge du tamis moléculaire étant située dans la plage allant de 4% à 45% en poids. Le rapport pondéral entre le principe actif dans le catalyseur A et le catalyseur B se situe dans la plage allant de 0,1 à 20, et de préférence de 0,3 à 5. Le procédé de réaction présente une sélectivité élevée en oléfines légères, la somme de la sélectivité des oléfines légères comprenant de l'éthylène, du propylène et du butène étant située dans la plage allant de 50 à 90%. De plus, la sélectivité du sous-produit méthane est inférieure à 15%. L'invention présente d'excellentes perspectives d'application.
