The Changyi Petrochemical Co recently asked Zhang Kongyua, a senior engineer at China University of Petroleum, to share his knowledge about the functions of mixed-hydrogenation catalysts on gasoline and diesel in the coking unit.
Participants spoke about their experiences with catalyst physicochemical properties and operating conditions and discussed the effect of catalysts in different gasolines.
Thanks to this technological exchange, the participants were able to see that heavy and inferior crude oil can lead to an increase in carbon deposits on the surface of catalysts in the refining system of the coking unit and could deactivate catalysts and lower the quality of gasoline and diesel.
The meeting also improved the technicians' understanding of reaction principles and selection factors of hydrogenation catalysts in the coking unit.
