摘　　要：旨在废旧轮胎热解基础特性基础上,综合评估一项炼油中试工艺的产物特征、环境污染及效益.研究发现,热解温度区间为300~350℃时,该工艺所产生的CO_(2)、SO_(2)以及NO_(x)等气体污染物较少,具有环保潜力.在不同热解温度下产生的重型燃料油成分及含量分析中,250~350℃温度区间产出的重型燃料油最符合预期定位,其中沥青质含量较低,范围为4.45~5.68%,而烯烃含量较高,范围为18.27~25.18%.经综合评估,中试工艺最优生产温度条件为350℃,年利润为198.18万元,资金回收周期为34个月.研究结果从技术、环境和经济三方面综合评价并优化废旧轮胎低温裂解炼油中试工艺,可为废旧轮胎的回收利用提供技术支撑和应用实践.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.
