Tyre Recycling Through Pyrolysis Process

[qingxiang]

Millions of tons of plastic and tire waste are produced in the world every year. Most of these wastes are either burnt or used for filling land. Burning emits harmful gases and creates threats to the environment. technology emerged as a solution for decomposing plastic and tire waste. Pyrolysis involves carbonaceous material's thermal decomposition in an oxygen free environment. In this process, the pressure of the system is not restricted by the pressure of water vapor. In other words, Pyrolysis is the process of heating biomass without oxygen. This method waste tyre dispose machine is considered to be useful in reducing plastic and tire wastes. It also allows recycling some useful energy stored in the biomass.

Application of helps to recover energy in plastic waste and tire waste rubber floor tiles hydraulic press through chemical manipulation. Plastic recycling through process consists of several steps. All plastic waste needs to be sorted before putting it through the process. Mechanical recycling includes shredding of polymers and cryogenic grinding of plastics. Through process, the long chain molecules of polymer are cracked into smaller chains with the help of pressure and heat. Actually it is similar to nature's process where the earth breaks down carbon and produces oil. This natural process takes millions of years. The process of plastic produces mainly three products: Bio-oil, Bio-char and Syngas.

Bio-oil or Pyrolysis oil can be considered as a substitute for industrial diesel. Pyrolysis oil is also used in boilers, furnace, electric generators, diesel pumps, hot air/water generators, heaters, thermic fluids, and other equipment. Syngas is reused in plants and the bio-char or carbon black is put to use in plastic/rubber industries and also in inks, paints etc. High calorific value biomass can only be pyrolised in order to generate bio-oil.

Tyre recycling of rubber extruder exporter through the process involves heating of whole or shredded tyres without oxygen in a closed vessel reactor. Rubber polymers will break down and form smaller molecules. Vaporized smaller molecules are burnt further to produce bio-oil or oil. Solid, liquid and gaseous properties are derived from tyre process in accordance with the process conditions and feed-stock used. A major issue related to tyre is the generation of solid stream, which constitutes about 40% of the total output. Steel from solid stream is removed with the help of magnets but the remaining bio-char has no value other than being a carbon fuel of lower grade.
