Significance and Use

The determination of the total volume % of saturates, olefins, and aromatics in petroleum fractions is important in characterizing the quality of petroleum fractions as gasoline blending components and as feeds to catalytic reforming processes. This information is also important in characterizing petroleum fractions and products from catalytic reforming and from thermal and catalytic cracking as blending components for motor and aviation fuels.

GD-11132 Hydrocarbon Test Machine is designed and made as per the National Standard of People’s Republic of China GB/T11132-2002 “Test Methods for Hydrocarbon of Liquid Petroleum Product (Fluorescence Indicator Absorption Method)”. It uses fluorescence indicator to let the hydrocarbon in the liquid petroleum products shown on the absorption column, and calculates its percentage by volume as per GB/T11132. It is taken as an important quality index of engine fuels and aviation fuels.

The instrument is specially used to determine aromatic hydrocarbon, olefin hydrocarbon, and saturation hydrocarbon in the distillate.

I. Main technical characteristics
