Embodiment 1
[0010] Use this method to process myrcene, proceed as follows: put 110 grams of β-pinene mixture with a β-pinene content of 95.1% into the vaporizer, start vacuuming and heating; vacuum degree is controlled at -0.075Mpa~-0.085MPa , heat the temperature to 110°C, and control the evaporation of the material in the vaporizer for 30 minutes to form β-pinene gas. The β-pinene gas enters the mixer and mixes with nitrogen gas 5 times the volume of the β-pinene gas. The temperature is controlled at 90°C; then it enters the preheater for preheating, the mixed gas in the preheater reaches 240°C, and then the mixed gas enters the cracking tube with the catalyst layer under vacuum, so that the catalyst in the catalyst layer enters the mixed In the gas; the catalyst layer here is a zeolite molecular sieve catalyst; the temperature of the cracking tube is divided into three temperature sections along the axial direction of the tube. The vacuum degree of cracking tube: -0.085Mpa. The cleava...
Embodiment 2
[0012] Use this method to process myrcene, proceed as follows: put 530 grams of β-pinene mixture with a β-pinene content of 95.6% into the vaporizer, start vacuuming and heating; vacuum degree is controlled at -0.08Mpa~-0.09MPa , heat the temperature to 90°C, and control the evaporation of the material in the evaporator for 90 minutes to form β-pinene gas. The β-pinene gas enters the mixer and mixes with nitrogen gas that is 3 times the volume of the β-pinene gas. The mixing temperature is controlled at 100°C; the mixed gas in the preheater reaches 230°C, and then the mixed gas enters the cracking tube with a catalyst layer under vacuum, so that the catalyst in the catalyst layer enters the mixed gas; the catalyst layer here is Zeolite molecular sieve catalyst; the temperature of the cracking tube is divided into three temperature sections along the axial direction of the tube. The temperature measuring points set at the three points are 400°C, 440°C, and 500°C, and the vacuum ...
Embodiment 3
[0014] Use this method to process myrcene, proceed as follows: put 1580 grams of β-pinene mixture with a β-pinene content of 96.1% into the vaporizer, start vacuuming and heating; vacuum degree is controlled at -0.09Mpa~-0.098MPa , heating the temperature to 80°C, and controlling the evaporation of the material in the evaporator for 150 minutes to form β-pinene gas. The β-pinene gas enters the mixer and mixes with the nitrogen gas of the same volume as the β-pinene gas. Control at 120°C; the mixed gas in the preheater reaches 250°C, and then the mixed gas enters the cracking tube with a catalyst layer under vacuum, so that the catalyst in the catalyst layer enters the mixed gas; the temperature of the cracking tube is along the tube body The axial direction is divided into three temperature sections and the temperature measurement points are set. The temperatures measured at the three points are 350°C, 400°C, and 560°C, and the vacuum degree of the cracking tube: -0.075Mpa. Th...
