Examples
Embodiment 1
[0122] Add 1-methylnaphthalene to the heavy oil that is mined or / and exported to reduce the viscosity of the heavy oil, thereby reducing the flow resistance of the heavy oil, and making the heavy oil flow smoothly;
[0123] Tests show that: adding the 1-methylnaphthalene to the heavy oil can effectively reduce the viscosity of the heavy oil (see the test data in Table 3 of the test results);
Embodiment 2
[0125] Repeat Example 1, except that: in order to prevent the 1-methylnaphthalene from generating crystals, solids or solidification in a low temperature environment, fusel oil is added to the 1-methylnaphthalene;
[0126] The fusel oil refers to any one of fusel oil from the by-product of alcohol production by fermentation and fusel oil from the by-product of butadiene production by alcohol, or a mixture of them in any ratio;
[0127] Any one of the fusel oils is a commodity or can be purchased from the market;
[0128] The added fusel oil ensures that the 1-methylnaphthalene is always liquid in a low temperature environment, and does not produce crystals, solids or solidification.
Embodiment 3
[0130] Repeat Example 1, except that: in order to prevent the 1-methylnaphthalene from generating crystals, solids or solidification in a low temperature environment, a special organic solvent is added to the 1-methylnaphthalene;
[0131] The special organic solvent refers to any of alcohols (such as octanol, isoamyl alcohol, etc.), glycol derivatives (such as ethylene glycol butyl ether, diethylene glycol butyl ether, diethylene glycol ethyl ether, etc.) One or a mixture of any two or more of them in any ratio;
[0132] Any one of the special organic solvents is a commodity or can be purchased from the market;
[0133] The added special organic solvent ensures that the 1-methylnaphthalene is always liquid in a low temperature environment, and does not produce crystals, solids or solidification.
