Introduction
This instrument is suitable for petroleum products and samples whose temperature is lower than 80ºC and can flow. It is also suitable for the measurement of petroleum asphalt and residual oil.
A membrane filter of known weight is filtered, then dried, and then the weight of the insoluble matter filtered by the membrane filter is weighed. The principle of measuring asphalt is to use n-heptane to precipitate asphaltenes from the sample. After filtering, use n-heptane to reflux to remove the soluble components contained in the precipitate, and then use toluene to reflux to dissolve the precipitate to obtain asphaltenes. The deasphalted part is adsorbed on an alumina chromatographic column, and then washed out with n-heptane (or petroleum ether), toluene, toluene-ethanol, and correspondingly saturated components, aromatic components, and gums are obtained.
