Abstract: Process for producing phenol, cresol and xylenes from a coal-derived feed are described. The processes combine dealkylation of alkylphenols from coal derived liquids followed by benzene and/or toluene transalkylation to reduce the production of non-ideal alkylbenzenes and reduce the usage of benzene/toluene. Alkylphenols from the coal derived liquids are converted in a dealkylation reaction zone comprising a dealkylation reactor to make phenol. The unconverted alkylphenols and an aromatic compound, such as benzene or toluene, are fed to a transalkylation reaction zone comprising a transalkylation reactor to make more phenol. Cresols and xylenes can also be produced.

Abstract: Transalkylation processes using catalysts comprising three dimensional 12 membered ring zeolites with a combination of small and large pores are described. These catalysts have increased conversion of alkylphenols to phenol, cresols, and alkylbenzenes from coal-derived liquid streams compared to catalysts consisting of HZSM-5 zeolite.

Abstract: Processes for producing cresol from an alkylphenol stream involve transalkylating the longer-chain alkylphenols (i.e., having an alkyl chain with 2 or more carbon atoms) with an aromatic solvent such as benzene and/or toluene in a first transalky lation reaction zone to obtain phenol, cresol, xylenol, trimethylphenol, and alkylbenzenes. The xylenols and trimethylphenols are reacted with phenol in a second transalkylation reactor to obtain the desired cresols. Xylenes can also be produced.

Abstract: A machine learning application method, a device, an electronic apparatus, and a storage medium, used to directly link service scenarios, aggregate data related to the service scenarios, accordingly explore modeling schemes, and ensure that data used in offline modeling scheme exploration and data used in an online model prediction service have the same source, thereby realizing consistency of source of offline and online data. Directly deploying an offline model to an online environment results in data inconsistency between online feature computation and offline feature computation, which in turn causes poor prediction performance; therefore, only a modeling scheme is deployed online, and the offline model is not deployed. After a modeling scheme is deployed online, sample data having a feature and feedback can be obtained by receiving a prediction request, thereby enabling model self-learning by means of the sample data.
