Title:
MFI-ZEOLITE-CONTAINING HYDROCARBON CONVERSION CATALYST AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/063290
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of the preparation of molecular sieve catalysts, and relates to an MFI-zeolite-containing hydrocarbon conversion catalyst and a preparation method therefor. The catalyst contains a zeolite including a zeolite with an MFI structure, a phosphorus-containing matrix material, and a heat-resistant inorganic oxide, wherein the phosphorus-containing matrix material contains 5-94.5% by weight of aluminum oxide, 5-94.5% by weight of manganese oxide, and 0.5-10% by weight of phosphorus oxide, and the specific heat capacity is 1.3-2.0 J/(g·K). The preparation method therefor comprises: forming a phosphorus-containing matrix material, a zeolite, a heat-resistant inorganic oxide binder, optional clay, and an optional auxiliary compound into a slurry, and spray drying the slurry. The catalyst has a good metal-contamination resistance and wear resistance, is used for the conversion of heavy oil, and has a relatively high heavy oil conversion capacity, a high light olefin yield, and unexpectedly, a relatively high light aromatic hydrocarbon yield.
