Conclusions Study of deasphalting with propane of the tar from a mixture of Uzen' and Zhetybai petroleums in two stages showed the effectiveness of extracting the oily components and solid hydrocarbons under the following conditions: 51 dilution by weight in each stage, and temperature range at the top of the column 65–75°C.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 2, pp. 16–18, February, 1968. 相似文献

A new method of determining the solid point and flow point of crude oil and petroleum products, crystallization/melting of
waxes in petroleum products, and the Phazaphot instrument for implementing the method are described. The method consists of
recording the intensity of light mirror-reflected from the surface of the sample during structural transitions when the temperature
changes. The new principle of measurements allowed significantly simplifying implementation of the method, making the determinations
faster, and expanding the range of objects investigated and problems solved.

The physicochemical properties of liquid biofuels of different types (bioalcohols, biodiesel, etc.) in comparison to the same
characteristics of petroleum fuels were examined. The advantages and disadvantages of biofuels with respect to these characteristics
were demonstrated. 相似文献
