The diposing and recycling of waste rubber is the important and difficult point in the world rubber industry. Pyrolysis is environmentally-friendly and potential solid waste treatment method

attracting a large number of people's attention. The pyrolysis of scrap rubber can solve the environmental pollution efficiently caused by these dumped rubber

but also can recycle three useful products: pyrolytic carbon

pyrolytic oil and gas. The typical pyrolysis reactors and techniques of waste rubber are overviewed in this paper

including vacuum-moving bed reactor

fixed bed reactor

fluidized bed reactor

rotary kiln reactor

microwave assisted pyrolysis and catalytic pyrolysis. The effects of the main process conditions are systematically outlined. The composition

physicochemical properties and application of the resulting products are also detailed analysis. The key of waste rubber pyrolysis is to obtain high-quality products

while reducing the consumption of energy to the greatest extent. As a result

to develop an economic

energy-saving and to obtain higher value of pyrolytic products is the main direction of waste rubber pyrolysis technology.
