Embodiment 1
[0052] In this embodiment, according to the flow process shown in the accompanying drawings, the experimental raw material is coumarone resin raw material, and the first-stage hydrogenation catalyst uses a highly active nickel metal hydrogenation catalyst (Ni content 15-30%) produced by the Shanxi Coal Chemical Industry Institute of the Chinese Academy of Sciences, which is resistant to melting and oxidation. aluminum and silica carrier), the two-stage hydrogenation catalyst uses the palladium metal hydrorefining catalyst (5% Pt content, refractory alumina and silica carrier) produced by the Shanxi Coal Chemical Industry Institute of the Chinese Academy of Sciences, and the above-mentioned catalysts are all clover-shaped and inert The catalyst uses alumina active ceramic balls with large pores; the process conditions are shown in Table 1, and the experimental results are shown in Table 4.
