摘　　要：近年来,无灰分散剂的发展呈现多功能化的趋势,即通过一种多功能化的低剂量的无灰分散剂,在表现出优异的分散性的同时,还可有效解决随之引起的油品粘度增长等问题。本文主要调研了近年来美国专利中所报道的无灰分散剂,依据调研结果总结了无灰分散剂近几年的发展方向。In recent years, the development of ashless dispersant shows a trend of multi-function, that is, through amulti- functional low-dose ashless dispersant, it can not only show excellent dispersion, but also effectively solve theproblem of oil viscosity growth. This paper mainly investigates the ashless dispersants reported in American patents inrecent years, and summarizes the development direction of ashless dispersants in recent years.
