The whole world is always devoting to the research and development of complete recovery and high added economic value technology of waste rubber. Shanghai Kimkey Environmental S&T Co., Ltd. has scored great achievement in the field of waste rubber renovation, recycling and utilization.

The company has launched "a whole set of industrialized integrated control waste rubber tyre catalysis-free pyrolysis equipments" while improving the pyrolysis technology continuously. The set of equipments can pyrolyze waste tyres and rubber to high quality fuel oil, carbon black, steel wire, gas and other resources and material in short supply under the relative low temperature of 400℃, among which gas and some fuel oils has realized the self-sufficiency of production system and entered industrialized development stage, which has significant meaning on solving the recycling problem of waste rubber, eliminating secondary pollution, relieving energy crisis and realizing resource recycling, etc.

Through comprehensive testing and analysis of the principle of waste tyre pyrolysis, low temperature catalytic reaction free medium, composition of pyrolysis products and physical and chemical properties and by controlling the pyrolysis temperature, pressure, medium and material staying period, "the whole set of industrialized integrated control waste rubber tyre catalysis-free pyrolysis equipments" makes use of the special designed structure of low temperature catalytic reaction free pyrolysis moving bed reactor to pyrolyze the waste tyres to high quality liquid fuel oil, carbon black and small amount of gas under low temperature. The non-condensable gas produced by pyrolysis will enter the heat supply device to be reused in the production line after passing through special purification device, which realizes the self-sufficiency of heat supply of the system. Finally the exhaust gas will be exchanged through preheating and discharged without harm after water film dedusting and purification, which possesses the industrialization promotion basis and conditions of green energy saving and environmental protection type waste tyre pyrolysis technology and equipments. The whole set of equipments adopt PLC intelligent communication control, which is of low energy consumption, high hear efficiency, no pollution and full-automatic sealed cleaning.

One production line of industrialized integrated control waste rubber tyre catalysis-free pyrolysis equipments is able to dispose 10,000 ton waste tyres annually with annual operation period of 300 days and daily disposal volume of 34 ton waste tyres, which has remarkable economic efficiency. After adopting high efficiency waste tyre production line disposal, the recycling and high-valued utilization of the production line is 100% and the percent conversion is no less than 99%. A statistic shows that the production rate of pyrolytic fuel oil products is about 35%; the production rate of steel wire is about 30% and the production rate of carbon black is about 30%; the others are gas, which completely realized zero pollution production with remarkable energy saving and environmental protection effect.

Nowadays, the industrial development requires more and more fuels and chemical products. However, the global fixed resources are limited. Therefore, it is necessary to promote recycled economy and realize the recycling utilization of waste resources. The pyrolysis of waste tyre is only a kind of waste disposal technology. The application of pyrolytic products is the key of realizing recycling utilization. The products produced in low temperature pyrolysis of waste tyres has high oil heat value (>40MK/Kg), which can be used as fuel as a whole. Besides, since there is much light pyrolysis arene benzene, toluene and dimethylbenzene in the oil products. Such substances can be abstracted from the oil products. Meanwhile carbon black, steel wire are also important industrial raw materials, which can relieve the national and social energy and resource crisis and infuse fresh blood into the rapid development of industrialization.

The adoption of new technology can help to promote the conversion of traditional production way, improve the resource use ratio and increase the economic benefit of environmental protection; promote the adjustment of product structure and technology structure and accelerate the promotion of self-owned brands; increase the national revenue and local financial revenue, improve the independent innovation capacity of national environmental protection industry, the international competitiveness and the comprehensive national strength.

The "industrialized integrated control waste rubber tyre pyrolysis production line project" of Shanghai Kimkey Environmental S&T Co., Ltd. meets the idea of "recycling economy" and is an important practice of executing "the 12th 5-year" environmental protection planning. In the future, more and more enterprises are required to pay attention to the environmental protection ideas, emphasize on the research, development and application of science and technology, innovate continuously, build a mature operation mechanism and industrial chain, promote the recycling utilization of waste tyre and make contributions to the environmental protection industry of our country.
