When used in the catalytic conversion of alkyl aromatic hydrocarbons, the catalyst exhibits high reaction activity, low aromatic hydrocarbon loss rate.

Abstract: A method for model production includes acquiring a related operation for model production from a user interface layer of a model production system, and determining a software platform of the model production system; acquiring a model service corresponding to the related operation by invoking an application programming interface (API) corresponding to the related operation, wherein the API is located between the user interface layer and other layer in the model production system; performing the model service by invoking local resources of the software platform with a tool of the software platform adapted to the model service, to generate a target model; and applying the target model in a target usage scene.

Abstract: High-yield mammalian transient expression systems can include a cell culture media (particularly serum free, non-animal derived, and/or chemically defined media) for introducing macromolecules and compounds (e.g., nucleic acid molecules) into cells (e.g., eukaryotic cells). Cells containing such introduced materials can then be cultured in the cell culture media. In particular, the invention allows introduction of nucleic acid molecules (e.g., vectors) into cells (particularly mammalian cells) and expression of proteins encoded by the nucleic acid molecules in the cells. The invention obviates the need to change the cell culture medium each time a different procedure is performed with the cells (e.g., culturing cells vs. transfecting cells). The invention also relates to compositions and kits useful for culturing and transforming/transfecting cells.

Abstract: A catalyst for producing light aromatics with heavy aromatics, a method for preparing the catalyst, and a use thereof are disclosed. The catalyst comprises a carrier, component (1), and component (2), wherein component (1) comprises one metal element or more metal elements selected from a group consisting of Pt, Pd, Ir, and Rh, and component (2) comprises one metal element or more metal elements selected from a group consisting of IA group, IIA group, IIIA group, IVA group, IB group, IIB group, IIIB group, IVB group, VB group, VIB group, VIIB group, La group, and VIII group other than Pt, Pd, Ir, and Rh. The catalyst can be used for producing light aromatics with heavy aromatics, whereby heavy aromatics hydrogenation selectivity and light aromatics yield can be improved.
