Abstract: The industrial application of the new process, where the diesel products, are hydrocracking again was conducted to increase jet fuel and naphtha in a 3.6Mt/a hydrocracking unit of CNOOC Huizhou Petrochemical Co, Ltd. Without changing the device structure and the catalyst, the conversion rate of diesel reach 75%, target products (jet fuel, naphtha) yield increases by 3.29%, the smoke point of jet fuel has no significant change, the cetane number of diesel increases by 3.9 units,. The quality of the products meets their respective standards. The energy consumption of the device is slightly increased from 856.21 MJ/t to 859.72MJ/t raw material.

Key words: hydrocracking, diesel, recycling, jet fuel, naphtha
