摘要
A hydrocarbon distillate fraction is hydrotreated in a single stage by passing the distillate fraction downwardly over a stacked bed of two hydrotreating catalysts. The catalyst in the upper bed contains 0.1 to 15% by weight of platinum and/or palladium and also contains 2 to 40% by weight of at least one of tungsten, chromium, a Group VIIB metal, and an actinium series metal supported on an acidic refractory oxide carrier. The catalyst in the lower bed contains 1 to 15% by weight of a non-noble Group VIII metal and 1 to 25% by weight of a Group VIB metal on an amorphous, refractory oxide carrier. The liquid hydrocarbon product recovered has a reduced content of aromatics and a reduced heteroatom content.
