Embodiment 1-7
[0067] Embodiment 1-7 utilizes above-mentioned separation equipment and separation method to separate the Fischer-Tropsch wax and catalyst mixture sample prepared by the laboratory, the composition of the extractant used is shown in Table 2, the recovery rate of separation sample, heating mantle temperature, separation time, catalyst See Table 3.
Embodiment 8
[0075] Example 8 The product wax with black substance actually produced by the Fischer-Tropsch device was separated using the separation equipment assembled above. The extraction agent was toluene, and the temperature of the heating mantle was 120°C. The quality of the separated product wax and the separation results are shown in Table 4.
