The preparation and performance of a new catalyst for the alkylation of benzene and olefins by the Natural Science Foundation of Heilongjiang Province undertaken by Harbin Normal University has yielded satisfactory results. The research published 5 academic papers in internationally renowned publications, applied for 2 national invention patents, and won the second prize for science and technology of universities in Heilongjiang Province.

The project team prepared a new type of solid acid and acidic ionic liquid catalytic material, and characterized the prepared solid acid, and determined the composition of solid acid. The catalytic activity of the alkylation reaction was investigated using the prepared solid acid and acidic ionic liquid materials. The results show that the prepared solid acid has high activity for the alkylation reaction and selectivity of the target product. At the same time, the synthesis of diphenylmethane by alkylation under the catalysis of acidic ionic liquids has also obtained satisfactory results, and its activity and selectivity to target products are very high.

Sorting System

The general logistics automatic Sorting System workflow is mainly divided into confluence → sorting signal input → sorting and diversion → sorting.

1. Confluence: The materials picked from different positions according to the picking instruction are sent to the pre-processing equipment in a certain way, and collected by the pre-processing equipment to the main conveyor line. This process is called confluence.

2. Sorting: The signal input reaches the material on the main conveyor line, and the basic information of the material is read through an automatic identification device (such as a barcode scanner, etc.), and the computer handles the read material information accordingly. This process is called Input for sorting signal.

3. Diversion: After the material information is read into the computer system, it continues to move on the main conveying line. The storage rack sorting system detects the moving position of the material in real time. When the material reaches the corresponding sorting crossing, the control system sends a sorting mechanism to the sorting mechanism. After picking up the order, the sorting mechanism immediately produces corresponding actions to make the material enter the corresponding sorting gate, this process is called diversion.

4. Sorting: The materials entering the sorting crossing finally reach the terminal of the sorting system, and are sorted and transported to the corresponding area by manual or mechanical handling tools.

The essence of retail in the future will remain cost, efficiency and experience at the center. The sorting capacity of some sorting centers can reach 9,000 pieces per hour. Under the premise of the same site size and sorting volume, it is estimated that each site can save 180 manpower.
