摘要： 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.

摘要： A catalyst for converting hydrocarbon, a method of making the same, and a method of using the same are provided. Such a catalyst includes a zeotype microporous material, a binder material, and a metal phosphide, which can be in a range of from 0.01% to 10% by weight of a total weight of the catalyst. For example, such a catalyst can be used to convert light alkene or alkane into aromatic hydrocarbon such as benzene, toluene, xylenes, and a combination thereof. The alkene may be ethylene, propylene, butylene, or a combination thereof. The alkene may be supplied directly or from a stream converted from light alkane such as methane, ethane, propane, butane, or a combination thereof.

摘要： 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.

摘要： 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—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.
