摘要
将与国际标准相应的GB/T12574测定喷气燃料酸值,与采用GB/T264测定喷气燃料产品的酸值做了比较,两者结果之间存在较大差异。并通过对总酸值分布规律的研究后,指出一般来说,含有较高的总酸值的原油,一般也对应着较高的密度,及以石油酸并不一定都分布在200～400℃沸点范围,而是有多种分布形式和多峰型分布。
According to international practice GB/T12574, the results had big difference between the corresponding national standards GB/T264 and GB/T12574. Through the research of acid number distribution, most crude oil with high acid number had high density. Petroleum acid was not all at the distribution of 200 -400℃ petroleum fractions, but with many kinds of distribution and peak distribution.
