A catalyst that includes heterogeneous metal carbide nanomaterials and a novel preparation method to synthesize the metal carbide nanomaterials under relatively mild conditions to form an encapsulated transition metal and/or transition metal carbide nanoclusters in a support and/or binder. The catalyst may include confined platinum carbide nanoclusters. The preparation may include the treatment of encapsulated platinum nanoclusters with ethane at elevated temperatures. The catalysts may be used for catalytic hydrocarbon conversions, which include but are not limited to, ethane aromatization, and for selective hydrogenation, with negligible green oil production.

Metal carbide nanomaterial catalysts and production method thereof

A method for aromatization of light alkanes, comprising: subjecting the light alkanes to dehydroaromatization reaction in the presence of aromatization catalysts including carriers and metal active components supported on the carriers, the metal active components include platinum, the carriers include zeolites and binders, and at least 80 wt. % of the metal active components are distributed on the zeolites. The method of the present disclosure may increase yield of the target product&#x2014;aromatic hydrocarbons, and the regenerated catalyst can still maintain high catalytic performance. In addition, the method of the present disclosure can meet the requirements of industrial applications.

Method for aromatization of light alkanes

A system and a method are provided for producing aromatics. Such a system includes a cracker unit configured to convert a light alkane into an olefin-containing hydrocarbon comprising at least one alkene, and an aromatization unit. The light alkane is selected from the group consisting of methane, ethane, propane, butane, and a combination thereof. The cracker unit is configured to at least partially feed the olefin-containing hydrocarbon into the aromatization unit. Such an olefin-containing hydrocarbon comprises at least 40 wt. % of the at least one alkene. The aromatization unit is used to convert the olefin-containing hydrocarbon therein into a product stream, which includes an aromatic hydrocarbon selected from the group consisting of benzene, toluene, xylenes, and a combination thereof.

System and process for converting light alkane to aromatics

The present discloses an aromatization catalyst, preparation process and application thereof and a low-carbon olefin aromatization process. The aromatization catalyst comprises a microporous material, a binder and a modifier; the microporous material is a zeolite molecular sieve, the binder is alumina, the modifier is phosphorus, and the molar ratio of the aluminum element in the binder to the phosphorus element is more than or equal to 1 and less than 5; the ratio of the acidity of the strongly acidic sites to the acidity of the weakly acidic sites of the olefin aromatization catalyst is less than 1.
