Example Embodiment

[0014] attached figure 1 It is a specific embodiment of the present invention. The invention is a middle distillate desulfurization device, comprising a crude oil tank, a desulfurization reaction tank and an adsorbent regeneration tank. The crude oil tank is communicated with the desulfurization reaction tank through a crude oil pump, and the desulfurization reaction tank is regenerated with the adsorbent through a solid-liquid separator. The tank is connected, and the desulfurization reaction tank is connected with an adsorbent storage tank.

[0015] Further, an ultrasonic generator is provided at the inner bottom of the adsorbent regeneration tank.

[0016] Further, the raw material composition of the adsorbent in the adsorbent storage tank is as follows: 20-50 parts of molecular sieve particles; 60-95 parts of ethanol solution; 9-16 parts of zinc oxide; 10-20 parts of manganese dioxide solution .
