Abstract: A catalytic cracking catalyst contains 10-70 wt % of a cracking active component, 10-60 wt % of a binder and 10-70 wt % of a clay. The cracking active component has 5-100 wt % of a first Y-type molecular sieve and 0-95 wt % of a second molecular sieve. The first Y-type molecular sieve is a modified molecular sieve based on the crystal modification of kaolin and has the sodium oxide content of less than 2 wt %. The process for preparing the catalyst includes the steps of vigorously mixing and stirring a cracking active component comprising a modified molecular sieve based on the crystal modification of kaolin, a binder and a clay with water; spray drying; washing; filtering; and drying. The catalyst is used in the catalytic cracking reaction of heavy oils, and has a good coke selectivity, as well as a higher heavy oil conversion rate.

Abstract: An image generation method includes: acquiring an original image and visual description information corresponding to the original image; and performing style transfer on the original image through a pre-trained style transfer model to obtain a target image in a preset style. The style transfer model includes a plurality of feature extraction modules, comprising a color feature extraction module for extracting a color feature and a non-color feature extraction module for extracting visual features other than the color feature. The color feature extraction module extracts the color feature of a target object based on the original image and the visual description information. The non-color feature extraction module extracts other visual features of the target object based on the visual description information. The style transfer model performs style transfer on the original image based on the extracted color feature and other visual features to obtain the target image.

Abstract: A pulse sequence method for realizing selective detection of multiple groups and/or molecules by simultaneously preparing nuclear spin singlets and/or singlet orders of the multiple groups and/or molecules. Taking an AGG molecule as an example, it is proposed to simultaneously prepare two pairs of uncoupled group signals of the AGG molecule into nuclear spin singlets and/or singlet orders, and eliminate magnetic resonance signals other than the nuclear spin singlets and/or singlet orders by using a pulsed gradient field, thereby realizing simultaneous selective observation of multiple group signals in the AGG molecule. Also disclosed is a method for simultaneously detecting group AGG-A in an AGG molecule and group Tau-C and group Tau-D in a Tau molecule. For the first time, the simultaneous preparation and signal selection of multiple nuclear spin singlets and/or singlet orders in a spin system is achieved.
