Abstract:

The results of physical and chemical studies of gas condensate fractions, including gasoline, kerosene and diesel, are presented. Experiments were carried out on the separation of gasoline, kerosene and diesel fuel from gas condensate into fractions. The analysis showed that the collected gas condensate contains 38.02 % gasoline with a boiling point of 180 °C, 20.87 % kerosene with a boiling point of 140–240 °C and 43.67 % diesel fuel with a boiling point of 180–360 °C. The 140–240 °C fraction was obtained by secondary distillation of the straight-run fraction. The data obtained confirm that t

This study explored the adsorption of carboxylic acids, especially free fatty acids (FFAs), present in biofuel (distilled fractions of bio-oil such as gasoline-like hydrocarbons, kerosene-like hydrocarbons, and diesel-like hydrocarbons) using red-mud-based adsorbents. The red mud was thermally activated at 40 °C and 600 °C and chemically activated with 0.25M, 1M, and 2M HCl. Analytical techniques were used to characterize the adsorbents’ properties. At the same time, the study examined factors like feed type, adsorbents, FFA contents, adsorbent percentage, activation temperature, acid solution

You must be familiar with the terms ‘LPG’ and ‘CNG’ used as fuels. LPG is the abbreviated form of liquified petroleum gas whereas CNG stands for compressed natural gas. Another term ‘LNG’ (liquified natural gas) is also in news these days. This is also a fuel and is obtained by liquifaction of natural gas. Petrol, diesel and kerosene oil are obtained by the fractional distillation of petroleum found under the earth’s crust. Coal gas is obtained
