摘　　要：通过自建实验台模拟瓦斯全循环油页岩干馏工艺并进行积碳实验,利用气相色谱仪对积碳反应前后瓦斯气组分性质进行分析。使用丙烯为碳源气,观察不同工况下(反应时间、壁面温度、气体流量)的积碳现象。结果表明:瓦斯气中主要积碳母体为烯烃,含量最高为丙烯。积碳量随反应时间和壁面温度(800℃以下)的增加而增加,随气体流量的增加而变化,流量达到30 m L·min^(-1)后积碳量开始减少。各工况对积碳现象的影响程度依次是反应时间>气体流量>壁面温度。To evaluate coking behavior of oil shale full cycle carbonization process,we established the experi-mental table independently. Determining that propylene is the main matrix coking among various of organic ga-ses of retorting gas of oil shale based on self-building experiment table and gas chromatography. I selected pro-pylene as carbon source to analysis the phenomenon of coking in different cases （ reaction time/wall tempera-ture/gas flow rate） . Coke amount increased with the longer reaction time and higher wall temperature （ under 800 ℃） ,Coke amount continuous increased with the increasing of gas flow rate until the gas flow rate reached 30 mL·min-1 meeting a sudden decrease. According to the result of experiments,the influence degree of co-king behavior by different cases is as follows：reaction time〉 gas flow rate 〉 wall temperature.
