Comprehensive assessment of the technological,environmental,and economic effects of pilot-scale oil refining by pyrolysis of waste tires
With the rapid development of the automobile industry,the problem of waste tires has been attracting more and more attentions.How to achieve effective recycling and safe disposal of waste tires has become a hot issue in current industrial practice.This study aimed to comprehensively evaluate the product characteristics,environmental pollution,and economic benefits of a pilot-scale refinery process,based on the basis of the pyrolysis characteristics of waste tires.It is found that when the pyrolysis temperature ranges was 300℃～350℃,it will result in fewer gaseous pollutants(such as carbon dioxide,sulfur dioxide and nitrogen oxides).Under different pyrolysis temperatures,the heavy fuel oil products at the temperature range of 250℃～350℃ was consistent with the expected results,with lower asphaltene content(4.45％～5.68％)and higher olefin content(18.27％～25.18％).The optimum production temperature conditions were explored to be 350℃,which resulted in an annual profit of CNY 1,981,800 and a payback period of 34 months.This work focus on the evaluation and optimization of the pilot-scale process of low-temperature pyrolysis oil refining waste tiresfrom the perspecitves of technology,environment,and economy,and can provide technical support and application practice for the recycling of waste tires in future.
