[0029] The hydrogenation reaction is carried out in a stainless steel tubular reactor, and the reactor is a stainless steel tubular reactor with a size of φ25mm×1000mm. Fill the reaction tube with 100mL hydrogenation catalyst to form a fixed bed. The hydrogenation catalyst is a supported catalyst with Ni as the active component and diatomaceous earth as the carrier. The weight percentage of Ni in the catalyst is 30-50%. The bottom is filled with inert ceramic balls. The fresh catalyst needs to be activated with hydrogen before feeding.
[0030] The desulfurization treatment of the hydrogenation product is carried out in a stainless steel tubular reactor with a size of φ25mm×1000mm. Fill the reactor with 200mL desulfurizer to form a fixed bed. The desulfurizer is modified granular activated carbon loaded with active components, the particle size is 3-6mm, the active components are CuO and ZnO, the content of active components in the desulfurizer is 2-5wt%, and the content of ...
