Issue 13, 2022 - A new generation of toluene disproportionation catalysts is put into use

Recently, the new generation of HAT-300S toluene disproportionation and alkyl transfer catalyst developed by Sinopec Shanghai Petrochemical Research Institute (hereinafter referred to as "Shanghai Institute") successfully carried out industrial tests in Hainan Refining and Chemical Co.
, Ltd.
, and the device was successfully fed at one time and the product quality reached the standard
.

HAT-300S catalyst breaks through the strict restrictions of traditional technology on the content of olefins and polycyclic aromatic hydrocarbons in raw materials, further optimizes the aromatic production process, lays a foundation for expanding the production of aromatic raw materials, improves the utilization rate of low-value resources, and promotes the development of
green energy-saving aromatic hydrocarbon technology.

The results of industrial tests show that the reaction temperature is reduced by 20 °C compared with the previous generation technology, the product selectivity is increased by 1%, and the hydrogen consumption is reduced by about 15%, which shows excellent applicability to raw materials, solves the problems of high bromine index of raw materials and limited heavy aromatic hydrocarbon separation tower in Hainan refining, and has significant
economic benefits.

Toluene disproportionation is the traditional dominant technology
of Shanghai Institute.
In recent years, the R&D team has developed and innovated on the basis of giving full play to the advantages of traditional technology, based on industrial development and enterprise needs, and has continued to make efforts in basic research, material development and functional integration, and has successively developed HAT-199, HAT-300 and other models of catalysts and green reaction processes, and successfully realized industrial applications
