摘要： A method of making a heat generating catalyst for hydrocarbon cracking. The method includes providing at least one mordenite framework-inverted (MFI) zeolite having a Si/Al molar ratio of 15 or greater and providing at least one metal oxide precursor. Further, the at least one metal oxide precursor is dispersed within a microstructure of the MFI zeolite catalyst. The method additionally includes calcining the heat generating material with the at least one metal oxide precursor dispersed within the microstructure of the MFI zeolite catalyst to form at least one metal oxide in situ. The heat generating catalyst includes at least one MFI zeolite and at least one metal oxide in a ratio between 50:50 and 95:5.

摘要： In accordance with one or more embodiments of the present disclosure, a method for producing aromatic compounds from pyrolysis gasoline includes splitting the pyrolysis gasoline into a stream comprising non-aromatic hydrocarbons and a stream comprising paraffinic hydrocarbons and aromatic hydrocarbons; aromatizing the stream comprising paraffinic hydrocarbons and aromatic hydrocarbons, thereby converting the stream comprising paraffinic hydrocarbons and aromatic hydrocarbons to a first stream comprising benzene-toluene-xylenes (BTX); hydrotreating the first stream comprising BTX in a selective hydrotreatment unit, thereby producing a de-olefinated stream comprising BTX; hydrodealkylating and transalkylating the de-olefinated stream comprising BTX in a hydrodealkylation-transalkylation unit, thereby producing a second stream comprising BTX, the second stream comprising BTX having a greater amount of benzene and xylenes than the first stream comprising BTX; and processing the second stream comprising BTX in an aromatics recovery complex, thereby producing the aromatic compounds comprising benzene, toluene, and xylenes.
