  • CHEMICAL-TYPE HYDROCRACKING CATALYST, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
    Publication number: 20230390749
    Abstract: A chemical-type hydrocracking catalyst contains the following components: a) a ? zeolite, b) a layered MWW-type zeolite with a lamellar thickness of 2-12 nm, c) a metal functional component, d) a binder, and optionally e) a metal function regulating component. The catalyst can be used in hydrocracking reactions of feedstock oils rich in polycyclic aromatics for producing light aromatics and light alkanes.

  • FULL CONVERSION METHOD AND DEVICE FOR PRODUCING LIGHT AROMATIC HYDROCARBONS FROM LIGHT CYCLE OIL
    Publication number: 20220275294
    Abstract: Provided are a full conversion process and a device thereof for producing light aromatic hydrocarbon from LCO. The process includes the steps of: subjecting LCO stream to hydrofining and impurity separation, then performing selective conversion reaction, and separating the mixed aromatic hydrocarbons generated to sequentially separate out light aromatic hydrocarbons such as benzene-toluene and xylene, C9A aromatic hydrocarbons, C10A aromatic hydrocarbons and a bottom heavy tail oil; feeding the bottom heavy tail oil into a post-saturation selective reactor, subjecting to high-selectivity hydrogenation saturation under the conditions of low temperature and low pressure to provide a product having one benzene ring, and then returning the product back to the selective conversion reactor.

  • Process for producing aromatics, p-xylene and terephthalic acid
    Patent number: 10358606
    Abstract: The present invention relates to a process for producing aromatics, p-xylene and terephthalic acid. The process for producing aromatics comprises a step of contacting an oxygen-containing raw material with an aromatization catalyst, under aromatization reaction conditions, to produce aromatics. The process for producing aromatics has an advantage of high yield of carbon as aromatics.
