The removal of heteroatom impurities (S, N, O) from fossil fuel and biomass feedstocks is a critical step in the production of clean-burning transportation fuels. Nickel phosphide (Ni₂P) has emerged as a leading candidate material on which to base a new class of catalysts to compete with the long established Ni–Mo and Co–Mo sulfides for hydrotreating of crude oil feedstocks. A recent assessment by researchers at ExxonMobil suggested that a Ni₂P catalyst having a 3 nm particle size could compete with a state-of-the-art Co–Mo/Al₂O₃ catalyst for the hydrodesulfurization (HDS) of a straight-run gas oil feed. This article reviews recent advances in the low-temperature preparation of highly-active, nanoscale Ni₂P catalysts.

制备用于杂原子去除反应的纳米级磷化镍催化剂的新方法

从化石燃料和生物质原料中去除杂原子杂质（S，N，O）是清洁燃烧运输燃料生产中的关键步骤。磷化镍（Ni ₂ P）已成为一种主要的候选材料，在此基础上，新型催化剂可与历史悠久的Ni-Mo和Co-Mo硫化物竞争用于加氢处理原油原料。埃克森美孚（ExxonMobil）研究人员最近进行的一项评估表明，粒径为3 nm的Ni ₂ P催化剂可以与最先进的Co-Mo / Al ₂ O ₃催化剂竞争直馏塔的加氢脱硫（HDS）。运行瓦斯油进料。本文回顾了低温制备高活性，纳米级Ni _2的最新进展磷催化剂。
