氧化物催化剂上石脑油催化裂解制乙烯的研究

Catalytic cracking of naphtha to ethylene on oxide catalyst

使用固定流化床,考察了氧化物催化剂催化裂解石脑油制乙烯的反应。研究结果表明,温度、空速和水油比对裂解产物分布有直接影响。在反应温度700℃、空速0.75 h-1和水油质量比3∶1条件下,得到最大的乙烯收率为32.93%。

The performance of oxide catalyst for naphtha cracking was studied in a fixed-fluidized bed reactor. The influences of reaction temperature, WHSV and H2O/oil ratio were investigated. The maximum ethylene yield of 32.93 % was obtained under the eonditions of T = 700 ℃, WHSV = 0.75 h^-1 and H2O/oil mass ratio=3/1.
