Example Embodiment
[0015] Example 1
[0016] The microcrystalline wax raw material containing 3.11w% oil was used, the properties are shown in Table 1, and the catalyst is the catalyst A in Table 2.
[0017] The mixture of microcrystalline wax and hydrogen heated to a certain temperature enters the reactor. Under the action of the catalyst, by controlling the appropriate reaction conditions, the hydrodesulfurization, denitrification, deoxygenation and aromatic saturation reactions are carried out; After gas-liquid separation and vacuum deodorization, it becomes a white microcrystalline wax product. The process conditions and product properties are shown in Tables 3 and 4. The products in Table 4 meet the quality requirements of cosmetic-grade paraffin wax (SH0009-90), and the fused ring aromatic hydrocarbons meet the requirements of food paraffin wax standards.
Example Embodiment
[0018] Example 2
[0019] The raw material used in this example is 2.56% oil-containing microcrystalline wax raw material (see Table 1), the catalyst is the same as in Example 1, and the process conditions and product properties are shown in Tables 3 and 4, respectively.
Example Embodiment
[0020] Example 3
[0021] The raw material used in this implementation is a microcrystalline wax raw material with an oil content of 2.02% (see Table 1). The process conditions and product quality are shown in Tables 3 and 4, respectively.
