Examples
Embodiment 1
[0040] use figure 1 In the combined process shown in the figure, straight-run wax oil is selected as the raw material for hydrogenation to produce gasoline and diesel, and certain refining (nitrogen content 100ppm) and conversion depth (gasoline yield is about 10%) are controlled to a certain extent. It is 96wt%. The catalysts used in the examples are the commercial catalyst FF-36 hydrotreating catalyst, the special hydroconversion catalyst A, the commercial catalyst FC-18 hydrogenation upgrading catalyst and the C single-ring aromatic hydrocarbon retaining hydroconversion catalyst.
[0041] The properties of catalysts A and C are shown in Table 1, the properties of feed oil are shown in Table 2, and the operating conditions are shown in Table 3.
Embodiment 2
[0043]use figure 1 In the combined process shown, straight-run wax oil is selected as the raw material for hydrogenation to produce gasoline and diesel, and a certain refining (nitrogen content of 200ppm) and conversion depth (gasoline yield is about 10%) is controlled to a certain extent. It is 96wt%. The catalysts used in the examples are commercial catalyst FF-36 hydrotreating catalyst, special hydroconversion catalyst A, commercial catalyst FC-18 (hydrogenation upgrading catalyst) and single-ring aromatics retained hydroconversion catalyst C.
[0044] The properties of catalysts A and C are shown in Table 1, the properties of feed oil are shown in Table 2, and the operating conditions are shown in Table 3.
Embodiment 3
[0046] use figure 1 In the combined process flow shown, straight-run wax oil is selected as the conversion raw material for hydrogenation to produce gasoline, and certain refining (nitrogen content 200ppm) and conversion depth (gasoline yield is about 5%) are controlled to a certain extent. The diesel yield in the hydrogenation upgrading process is It is 96wt%. The catalysts used in the examples are the commercial catalyst FF-36 hydrotreating catalyst, the special hydroconversion catalyst A, the commercial catalyst FC-18 hydrogenation upgrading catalyst and the C single-ring aromatic hydrocarbon retaining hydroconversion catalyst.
[0047] The properties of catalysts A and C are shown in Table 1, the properties of feed oil are shown in Table 2, and the operating conditions are shown in Table 3.
