摘要
本文主要对载体ZrO_(2)的焙烧方式对CO_(2)-O_(2)联合重整CH_(4)反应的影响进行研究。考察了焙烧气氛、焙烧温度等对催化剂性能和CO_(2)-O_(2)联合重整CH_(4)反应性能的影响。研究结果表明:反应温度为800℃,W/F=0.5×10^(-4)g/(mL·h),原料气配比为V(CH_(4))∶V(CO_(2))∶V(O_(2))=4∶2∶1时,以流动氮气-静态空气800℃焙烧的载体制成Ni/ZrO_(2)催化剂进行CO_(2)-O_(2)联合重整反应,CH_(4)和CO_(2)转化率可达90%以上,且在400 min时间内,转化率变化较缓,说明催化剂活性和稳定性均较好。
This paper mainly focuses on the influence of roasting method of support on the reaction of CO_(2)-O_(2) reforming CH_(4) and examines the influence of roasting atmosphere and temperature on catalyst and the reaction of CO_(2)-O_(2reforming) CH_(4).The findings indicate that when the reaction temperature is 800 ℃,W/F=0.5×10^(-4)g/(mL·h^(-1)) and the feed gas radio is V(CH_(4)):V(CO_(2)):V(O_(2))=4:2:1,the Ni/ZrO_(2) catalyst is made into the support of flowing nitrogen-static air roasting at 800℃ for reforming reaction,the conversion rate of CH_(4and) CO_(2) can reach more than 90%,and the conversion rate is slow within 400 minutes,there is a minimal change in the conversion rates,which signifying the catalyst activity and stability are excellent.
