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...

Abstract

A process for preparing lemon oil extract, fuel oil and carbon black from used tyre by vacuum catalytic cracking includes such steps as proportionally mixing sodium hydroxide and zinc oxide to obtain catalyst, proportionally loading the catalyst and used tyre particles into vacuum catalytic cracking reactor, reacting to obtain gas mixture and carbon black residual in reactor, condensing the gas mixture to obtain the mixture of lemon oil extract, fuel and water, separating, and purifying. Its apparatus is also disclosed.

Description

Technical field [0001] The invention relates to a new method and device for comprehensive utilization of waste tires, in particular to a method and device for preparing lemon oil and carbon black by vacuum catalytic cracking waste tires. technical background [0002] With the rapid development of my country's automobile industry, a huge number of waste tires has caused a series of problems. At present, the simple accumulation of waste tires takes up a lot of land, pollutes groundwater, easily causes fires, emits harmful gases, and is a mosquito with germs. and parasites provide breeding grounds, endangering the environment and affecting human health and safety. Therefore, finding a suitable method to process waste tires has become one of the hotspots that people pay close attention to. With the gradual reduction of oil and natural gas reserves and the pressure of environmental protection in recent years, the research on obtaining liquid fuel from waste tires and recycling ca...
