AI Technical Summary

Technical Problem

Existing PNP and PCCP framework ligand catalysts exhibit low catalytic activity and poor selectivity in ethylene oligomerization, failing to meet the demands of industrial production.

Method used

Catalysts employing PNP-TRz ligand structures can improve thermal stability and catalytic activity through the selection and optimization of specific groups. Combined with alkylaluminum co-catalysts and metallic chromium compounds, high selectivity for target products and high yield efficiency can be achieved.

Benefits of technology

It achieves high thermal stability and high catalytic activity, improving the production efficiency of ethylene oligomerization reaction. The catalytic activity can reach more than 400 kg/gCr.h, and the total selectivity of 1-hexene and 1-octene can reach 85 wt%.
