废塑料制备燃料油热裂解与催化裂解工艺研究比较

对废塑料制备燃料油的热裂解和催化裂解两种不同工艺从技术、经济角度进行分析研究对比 ,证明热裂解具有工艺简单、设备投资少、无催化剂再生要求等特点 ,但产品质量差 ,汽油、轻柴油收率低是其主要缺陷 ,而催化裂解则反之。经过论证得出催化裂解工艺适用于大型化、集中处理废塑料的场合 ,热裂解适合于中小型生产的结论。

Study on the Process of Preparing Fuel Oil Using Waste Plastics by Method of Thermal Cracking and Catalytic Racking

In this paper,the method of thermal cracking and catalytic cracking used to prepare fuel oil using waste plastics was studied.The result shows that thermal cracking has the characteristics of being simple,low equipment investment and requires no catalyst.But the product quality is poor,especially the yield of light oil is low in the thermal cracking.On the contrary,catalytic cracking product properties from CC are better than from thermal cracking.The catalytic cracking is suitable for big-scale facilities dealing with concentrated waste plastics,the thermal cracking is suitable for medium or small-scale facilities to dealing with waste plastics.
