Embodiment 1
[0012] The non-hydrocatalytic refining test of reformed aromatic oil was carried out on a 10ml evaluation device to investigate the catalytic refining ability at different reaction temperatures. The catalyst was prepared by extruding, drying and roasting kaolin, bauxite and β-type molecular sieve (the same below). Using reformed heavy aromatic oil, distillation range 149~221℃, bromine index is 548.63mgBr / 100ml, aromatic content is 94.18%, colloid is 78mg / 100ml, colloid detection method is GB / T888019 (the same below), reaction conditions are :Reaction pressure 1.0Mpa, reaction space velocity is 25hr -1 , The test results are shown in Table 1. The results are shown in Table 1.

Embodiment 2
[0015] The non-hydrogen catalytic refining test of aromatic oil was carried out on a 10ml evaluation device to investigate the catalytic refining capacity under different reaction pressures. The feedstock oil was heavy aromatics in the reformer, the distillation range was 149-221°C, the bromine index was 548.63mgBr / 100ml, and the reaction conditions It is: reaction temperature is 160℃, reaction space velocity is 25hr -1 , The test results are shown in Table 2.
[0016] Reaction pressure, MPa
Embodiment 3
[0018] The non-hydrocatalytic refining test of aromatic oil was carried out on a 10ml evaluation device to investigate the catalytic refining capacity under different reaction space velocities. The feedstock oil was heavy aromatics in the reformer, the distillation range was 149-221°C, and the bromine index was 548.63mgBr / 100ml oil. The reaction conditions are: reaction temperature is 180°C, reaction pressure is 1.0Mpa, and the test results are shown in Table 3.
