Provided are an in situ bifunctional catalyst for deep desulfurization and increasing octane number of gasoline, and its preparation method and application. The bifunctional catalyst includes a modified catalyst carrier and a loaded active metal, where the modified catalyst carrier is a composite carrier prepared through mixing γ-AlOand an acidic molecular sieve by a binder and calcining. When the bifunctional catalyst provided by the present application is used for hydrodesulfurization of gasolines, deep desulfurization, olefin reduction and octane number preservation can be realized simultaneously, thereby obtaining a high-quality oil product.

Provided are a bifunctional catalyst for deep desulfurization and gasoline quality improvement and a preparation method therefore and a use thereof. The bifunctional catalyst includes a modified catalyst and a loaded active metal, where the modified catalyst carrier is a γ-AlOmodified with a rare earth element, or the modified catalyst carrier is a composite carrier prepared by mixing and calcinating γ-AlOand an acid molecular sieve through a binder, and then modifying with the rare earth element. The bifunctional catalyst for deep desulfurization and gasoline quality improvement can achieve deep desulfurization of high-sulfur fluid catalytic cracking gasoline, and ensure no significant loss of octane number under relatively mild conditions.

A method and a system for recommending a target garment matching an inputted garment. The method includes: extracting attributes from text description and image of the inputted garment to obtain extracted attributes; querying a knowledge graph using the extracted attributes to obtain matched attributes; retrieving candidate products from a garment pool using the matched attributes; extracting features from the inputted garment and the candidate products; determining the target garment from the candidate products based on grading scores between the features of the inputted garment and the features of the candidate products; and recommending the target garment. The knowledge graph includes nodes corresponding to type of clothes, category of clothes, attribute keys, values of attribute keys, context keys, values of context keys, combination of the values of the attribute keys and the type of clothes, and combination of the value of the attribute keys and the category of clothes.
