Abstract:

Using fluid catalytic cracking (FCC) slurry oil as feedstock, the process conditions for preparing coated asphalt were explored via high-temperature thermal condensation combined with air oxidation. The effects of reaction time, temperature, and gas flow rate on the properties of coated asphalt were investigated. Results showed that under the same oxidation reaction time, the softening point, toluene-insoluble content, quinoline-insoluble content, and coking value of the coated asphalt increased significantly with rising oxidation temperature. By combining thermal condensation and oxidation, coated asphalt with a softening point of 258.2 ℃, toluene-insoluble mass fraction of 51.1%, quinoline-insoluble mass fraction of 2.9%, and coking value of 70.2% was obtained under the conditions of 5 h oxidation time and oxidation temperature of (base temperature +10) ℃.

摘要：

以催化裂化油浆为原料，采取高温热缩合反应结合空气氧化反应的方式开展包覆沥青工艺条件的探索。考察了反应时间、反应温度和气体流量对包覆沥青性质的影响。研究结果表明：在相同氧化反应时间下，随着氧化反应温度的升高，包覆沥青的软化点、甲苯不溶物含量、喹啉不溶物含量、结焦值均明显升高。结合热缩合反应和氧化反应，在氧化反应温度为（基准温度+10）℃的条件下，氧化反应时间为5 h，可以得到软化点为258.2 ℃、甲苯不溶物质量分数为51.1%、喹啉不溶物质量分数为2.9%、结焦值为70.2%的包覆沥青。
