应用计算机信号处理技术测量汽油辛烷值

SIGNALS PROCESSING WITH COMPUTER AND ITS USE IN PETROLEUM PRODUCT ANALYSIS

利用计算机技术采集信号并经平滑、滤波等处理 ,得到烃类局部氧化参数。选取烃类局部氧化物理参数 (氧化诱导期、最高反应温度 )来表达并计算汽油辛烷值 ,并根据所建立的关系式测定汽油辛烷值。与标准实验比较 。

The sectional oxidation parameters of hydrocarbon, mainly oxidation in duction period and maximum reaction temperature, are obtained by use of computer technology for signal acquisition and processing such as smoothing and filterin g. The sectional oxidation parameters of hydrocarbon can be used to express and calculate octane numbers. The experimental results show that the octane numbers calculated by sectional oxidation parameters is coincident with that by standard testing method.
