Embodiment 1
[0079] This example is in figure 2In the system shown, the catalytic diesel with properties as described in Table 2 is used as the cracking raw material, the preheating temperature is 300°C; the carrier gas is nitrogen, the preheating temperature is 800°C, the molybdenum tube is used as the reactor, and the molybdenum tube is along the length direction Set vertically, the inner diameter is 10mm, the length is 38mm, and the outer circumference of the molybdenum tube is covered with an electromagnetic induction coil. From the inlet of the quenching medium on the upper part of the gas-solid separator 8, liquid nitrogen is passed into it as the quenching medium, the flow rate of liquid nitrogen is 4 liters / minute, and the cooling rate of the reaction product is controlled to be 200° C. / millisecond, so that its temperature is reduced to about 450° C. . The generated gas product containing acetylene enters the filter 9 through the gas outlet of the gas-solid separator 8 , and the ...
Embodiment 2-5
[0081] The reaction system and reaction process of embodiment 2-4 are basically the same as embodiment 1, and the only difference is that the reaction conditions are different, and the specific reaction conditions and reaction results are as shown in table 3;
Embodiment 5
[0082] The reaction system and reaction process of embodiment 5 and embodiment 1 are basically the same, the only difference is that the cracking raw material used is vacuum residue (see table 2 for properties), and the specific reaction conditions and reaction results are shown in table 4.
