Abstract��
In this article, the present situation of the diesel product in ZJ Petrochemical Company was analyzed, and new catalyst was selected by experiments. Two catalysts DN-3551 and DC-2551 of American Standard Company were compared, and the results showed that DN-3551 had better effect. It was proposed that, DN\|3551 can be used to increase diesel cetane number, drop the sulfur content and produce high-clean diesel in ZJ Petrochemical Company.
