废轮胎热解油气喷水急冷特性
Study on water spray quenching characteristics of waste tire pyrolysis oil-gas
摘要
Abstract
The flash point of waste tire pyrolysis oil obtained by conventional indirect heat transfer condensation is low.A water spray quenching technology for the condensation of pyrolytic oil and gas was proposed in this paper to solve the problem.The flash point and composition of pyrolysis oil were analyzed by closed cup flash test and GC-MS technique,and the water spray quenching characteristics of waste tire pyrolysis oil-gas were obtained.The results showed that water spray quenching technology condensed the oil-gas rapidly and reduced its partial pressure,thereby reducing the content of low flash point components in the pyrolysis oil significantly and increasing the flash point of the pyrolysis oil.The results of GC-MS analysis showed that the water spray quenching process reduced the content of low carbon components and increased the content of high carbon components in the pyrolysis oil,resulting in a shift in the carbon number distribution of pyrolysis oil components from low carbon to high carbon.Water spray quenching reduced the content of aliphatic hydrocarbons,monocyclic aromatic hydrocarbons(MAHs)and heteroatomic compounds in the pyrolysis oil while the content of polycyclic aromatic hydrocarbons(PAHs)was increased.The content of BTEX and D-limonene as high value-added products was also decreased.In addition,water spray quenching reduced the total content of components containing nitrogen or sulfur in the pyrolysis oil,wherein the content of nitrogen compounds and nitrogen-sulfur compounds decreased,while the content of sulfur compounds increased slightly.This study provided a reference for the research on the quality improvement and modification of waste tire pyrolysis oil.关键词
