With the increasing social modernization, on one hand, the rubber industry has been vigorously developing, and the rubber products have been widely used in all works of life; but on the other hand, more scrap articles are produced and accumulated to big amount as a result of erode-resistant characteristic of the rubber, thus posing a big public hazard to the environment and hygiene. What is worse, the problem has become more severe in recent years; hence, people vividly described it as black pollution. Compared with developed western countries, China are very inexperienced in handling the pollution of scrap rubber, besides, the fund and market are big problems too. China, today has leapfrogged to the third place in the world list of annual tire output, exceeding 0.13 billion. Waste tires left are over 65 million every year and the number will continue to rise by double digit yearly. 70% of waste tires are not reclaimed for use, besides, less than half of waste bias tires are reclaimed. China is currently suffering from an insufficient rubber source, which is mainly exported from outside countries. Hence, to improve the management of reclaiming waste tires has called an immediate action. A simplest method to handle rubber wastes is to produce reclaimed rubber powder and refine oil. Comparatively, producing reclaimed rubber restricts the future development of reusing rubber wastes as a result of its disadvantages like the high manufacturing cost, narrow sales channel and short service life of plastic runway and other products made. Oil refining has attracted peoples attention with its good sale, fast turnover speed on current fund and high margin. For instance, the average price for recycling waste tires in China is 1200 RMB/ton at present; the rate of oil refined from waste tires is up to 45% plus the production cost like fuel, labor, water and power expenses; therefore, to produce one ton of tire oil will only cost about 2600 RMB, compared with its current market price---3800RMB/ton
