Abstract: In view of the current domestic diesel market, hydrocracking wax oil with hydrotreated diesel was commercially practiced to broaden the range of raw materials, make full use of the capacity, improve the operation efficiency and reduce the comprehensive energy consumption of the hydrocracking unit. The commercial results showed that the hydrotreated diesel is converted into high value-added products such as heavy naphtha and aviation kerosene, which can greatly improve the economic benefit of the unit.

Key words: wax oil, hydrocracking, hydrotreated diesel, jet fuel
