Embodiment Construction
[0012] Further illustrate the present invention below in conjunction with accompanying drawing and embodiment:
[0013] Mix sodium hydroxide NaOH and zinc oxide ZnO with a weight ratio of 1.2: 1 to make a catalyst, add waste tire particles and catalyst to the vacuum catalytic cracking reactor 1 in a ratio of 1000 grams: 30 grams, and the reaction temperature is controlled by an electric heating furnace 2 And temperature controller 10 is controlled at 480 ℃, and the vacuum degree of vacuum catalytic cracking reactor is controlled at 3800Pa by vacuum relay 7 and electromagnetic valve 8, shows in vacuum pressure gauge 11, and the residence time of waste tire in vacuum catalytic cracking reactor is 23 Minutes, under the conditions described above, the waste tire particles undergo a catalytic cracking reaction, and the resulting mixed gas passes through the primary condenser 3 to condense the organic vapor and water vapor into a liquid, and collects it in the liquid collector 4, lea...
