Embodiment 1
[0051] This example is to illustrate that the method provided by the present invention separates the synthesized product obtained by the high-temperature Fischer-Tropsch synthesis process into different fractional segmented raw materials, and each enters the catalytic cracking effect of different reaction zones.
[0052] The experiment was carried out in a medium riser catalytic cracking unit. Such as figure 1 As shown, the riser reactor 1 of the medium-sized device has an inner diameter of 16 mm and a length of 3800 mm. The riser reactor 2 has an inner diameter of 16 mm and a length of 3200 mm. The outlet of the riser reactor 2 is connected to a dense-phase fluidized bed reaction. The fluidized bed reactor has an inner diameter of 64 mm and a height of 600 mm. The test is operated in a single pass. The 700℃ high temperature regenerant is introduced into the bottom of riser reactor 1 and 2 from the regenerator through the regeneration inclined pipe, and flows upward under the ac...
Embodiment 2
[0054] This embodiment illustrates the effect that the catalyst introduced into the riser reactor 2 is a mixed catalyst of a regenerating agent and a spent agent.
[0055] The experimental device is roughly the same as in Example 1. After the raw material 1-1 is preheated to 120°C and mixed with atomized steam, it enters the riser reactor 1 through the feed nozzle to contact the hot regenerant and undergo a catalytic conversion reaction, and the mixture of reaction oil gas and catalyst goes up, raw material 1 -3 After being preheated to 250°C and mixed with atomized steam, it enters the riser reactor 1 through the feed nozzle and contacts the upward reaction gas and catalyst mixture for catalytic conversion reaction, and the reaction gas and catalyst mixture are formed The mixture continues to move up the riser reactor 1, and separates gas and solid through the rapid separation device set at the outlet of the riser reactor 1. The separated reaction oil and gas are introduced into...
Embodiment 3
[0061] As shown in Example 2, the difference is that the refining pyrolysis light gasoline (distillation range 32~88℃) is mixed with the raw material 1-2 and then introduced into the lower part of the riser reactor 2 (introduced at the same height as the raw material 1-2 ). The mixture of reacted oil and gas and catalyst moves up the riser reactor 2 through the outlet of the riser reactor 2 and enters the fluidized bed reactor 3 to continue to participate in the cracking reaction. The reacted oil and gas are introduced into the settler and then introduced into the product separation system to separate into gas and liquid products. The refining pyrolysis light gasoline accounts for 10% of the total feed (including raw materials 1-1, raw materials 1-2 and raw materials 1-3) by weight.
