Embodiment 1
[0034] See figure 1 , A test method for evaluating coal-based CTL base oil oxidation characteristics, including the following steps:
[0035] S1, selected test tube or sample supplies used in coal-based CTL base oil test;
[0036] S2, called the coal-based CTL base oil sample for coal-based CTL base oil test;
[0037] S3, and the viscosity of the coal-based CTL base oil sample before testing, the numerical measure of the acid value, the test before the test is recorded as V1, and the acid value before the test is only T1;
[0038] S4, placed the sampled samples within a dry box that can be operated constant temperature.
[0039] S5, add metal catalyst, organic acid, and hydrogen peroxide, activate the drying box, and constantly warm to 80-150 ° C inside.
[0040] S6, coal-based CTL base oil samples are constantly baking in the drying box, and the reaction time of constant temperature baking is 48-72 hours;
[0041] After the constant temperature bake, the coal-based CTL base oil s...

[0058] A test method for evaluating coal-based CTL base oil oxidation characteristics, including the following steps:
[0059] S1, a test tube or a sample article for coal-based CTL base oil test, the test tube or sample article for the test, requires confirmation of the test tube or sample article inside the test, no doped other impurities ;
[0060] S2, 3 sets of coal-based CTL base oil samples for coal-based CTL base oil tests, the coal-based CTL base oil vial amount of coal-based CTL base oil samples is the same;
[0061] S3, and the ratio of motion viscosity before the coal-based CTL base oil sample and the numerical measure of the acid value, the viscosity of the test before the test, and the value of the acid value selected the state of the coal-based CTL base oil at 40 ° C, said Motion viscosity before the test is recorded as V1, and the acid value before the test is t1;
[0062] S4, placed the sampled samples within a dry box that can be operated constant temperature.
