1. A pretreatment desulfurization system comprising:
a first chute configured to supply coal conveyed by a belt conveyor to a pretreatment apparatus;
wherein, the pretreatment apparatus configured to desulfurize the supplied coal by immersing the supplied coal in a catalyst mixture in which a desulfurization catalyst and water are mixed, to produce a catalyst-immersed coal;
a mesh conveyor configured to separate the catalyst-immersed coal having passed through the pretreatment apparatus into a liquid phase and a catalyst-treated coal; and
a storage tank configured to store the separated catalyst-treated coal.
