助剂改性镍铈负载橄榄石焦油裂解催化剂的研究

摘要

以镍为活性组分,二氧化铈为助催化剂,橄榄石为载体研究了橄榄石负载镍催化剂的催化性能,实验还考察了不同助剂(Cu,Fe,Mg)的添加对催化剂活性的影响,结果表明,Cu,Fe,Mg都能提高Ce-Ni/Olivine催化剂焦油裂解活性和燃气质量,其中Cu效果最佳.%Ce-Ni/Olivine catalyst was prepared and the activity of cracking catalyst was invesitigated.The effect on the performance of catalysts with different additives (Cu,Fe,Mg) in the corresponding reaction conditions were investigated.The results show that Cu-Ce-Ni/Olivine catalyst possesed the best results on improving tar cracking activity and gas quality.
