Abstract
Methods are disclosed for the hydrotreating and hydrocracking of highly aromatic distillate feeds such as light cycle oil (LCO) to produce ultra low sulfur gasoline and diesel fuel. Optimization of hydrotreater severity improves the octane quality of the gasoline or naphtha fraction. In particular, the operation of the hydrotreater at reduced severity to allow at least about 20 ppm by weight of organic nitrogen into the hydrocracker feed is shown to lead to these important benefits. Post-treating of the hydrocracker effluent over an additional hydrotreating catalyst bed may be desired to meet specifications for ultra low sulfur fuel components.
