摘要： The hydrotreating of petroleum feedstock is improved by using a layered transition metal catalyst, a mixture of such catalysts or a stacked bed of transition metal catalysts that has a selected ratio of edge to rim sites sufficient to provide a product having a predetermined sulfur and nitrogen content.
In another aspect of the present invention, there is provided a method for selecting a transition metal catalyst system for use in hydrotreating nitrogen and sulfur containing feedstocks to provide a hydrotreated product having a predetermined nitrogen and sulfur content and at a predetermined reaction residence time, which method comprises: selecting the amount of sulfur and nitrogen to be removed from a given feedstock by hydrotreating to obtain a product having a predetermined nitrogen and sulfur content; determining the variation in the reaction kinetics for sulfur and nitrogen removal of the given feedstock by hydrotreating with a transition metal catalyst of varying edge to rim ratios; selecting, for a predetermined reaction residence time, that ratio from the varying edge to rim ratios of the transition metal catalyst that provides the requisite sulfur and nitrogen removal to provide the product of predetermined sulfur and nitrogen content.摘要翻译： 石油原料的加氢处理是通过使用层状过渡金属催化剂，谋求催化剂的混合物或过渡金属催化剂的叠式床改进确实具有边缘的至足以提供具有一预定的硫和氮含量的产品轮缘位点的选择的比率 ， 在本发明的另一个方面，提供了一种方法，用于选择的过渡金属的催化剂体系用于加氢处理的氮利用和含硫原料，以提供具有预定的氮和硫含量的加氢处理产物，并在预定的反应停留时间，这 方法包括：选择的硫和氮的量，以从给定的进料加氢处理以获得具有预定的氮和硫含量的产物中除去; 确定性采矿通过具有变化的边缘到轮缘比的过渡金属催化剂加氢处理在反应动力学对于给定的原料的硫和氮的去除的变化; 选择，在预定的反应停留时间，确实比从边缘变化与过渡金属催化剂的轮缘比率确实提供必要的硫和氮的去除，以提供预定的硫和氮含量的产品。
