摘 要: 以萘为生物质焦油模型化合物 ,在以白云石为载体制备的 Ni基催化剂上进行了催化裂解实验研究 ,对催化剂的制备技术、活性、积炭失活性能和再生方式进行了实验分析。结果表明 :在 70 0℃的裂解温度、重量空速 0 .8L· h-1的反应条件下 ,萘的单程转化率可达 95 %,以饱和湿空气为再生气流 ,在程序升温的条件下烧碳 ,催化剂再生时间短 (<0 .5 h) ,与同温度的热裂解相比催化裂解更有利于萘的深度裂解 . With naphthalene as model compound, the catalytic cracking experiments on biomass tar are made on Ni catalysts, and its catalyst preparation, activity, coke forming,and regeneration is analyzed. The results show that single conversion of naphthalene is 95% at space velocity 0.8 L·h -1 and 700 ℃; With saturated wet air as regeneration gas, the regeneration time is within 0.5 h; Compared with heat cracking at the same reaction temperature, the catalytic cracking is propitious to deep cracking of naphthalene.
