摘要

二氧化碳（CO

）和甲烷（CH

）是导致全球变暖的主要温室气体。CO

与CH

干重整（DRM）制合成气是解决温室气体问题的可行方案之一，但该反应催化剂易因积炭和金属烧结而失活。分别以活性炭（AC）、HZMS-5和炼铝灰渣（SA）为载体，采用超声浸渍法制备了镍质量分数为6%的催化剂6NiO/AC、6NiO/HZSM-5和6NiO/SA。采用固定床反应装置研究了该系列催化剂对DRM反应的催化性能，并通过XRD、N

吸/脱附、TG和SEM对催化剂进行了表征。结果表明，3种催化剂中，6NiO/SA的催化活性最低，6NiO/AC具有最大的比表面积和较小的金属晶粒，表现出比6NiO/HZSM-5和6NiO/SA更佳的催化活性，在

(CO

(CH

)为1、温度为900 ℃时反应60 min，6NiO/AC的CH

转化率和CO

转化率分别为91.4%和93.4%。在

(CO

(CH

)为1、温度为800 ℃和反应时间为240 min条件下考察了6NiO/AC的稳定性，发现其CH

转化率始终保持在70%左右。反应后6NiO/AC的积炭种类主要为丝状积炭，保证了催化剂的活性位点。另外，在反应体系中引入过量的CO

可使反应正向进行，促进了积炭气化反应并抑制了积炭形成。

Abstract

Carbon dioxide (CO

) and methane (CH

) are the main greenhouse gases that cause global warming. Dry reforming (DRM) of CO

and CH

to syngas is one of the feasible solutions to greenhouse gas problem

but the catalyst is easily deactivated due to carbon deposition and metal sintering. Catalysts 6NiO/AC

6NiO/HZSM-5 and 6NiO/SA with nickel mass fraction of 6% were prepared by ultrasonic impregnation method using activated carbon (AC)

HZMS-5 and aluminum slag as carriers. The catalytic performance of these catalysts for DRM reaction was studied in a fixed bed reactor

and the catalysts were characterized by XRD

adsorption/desorption

TG and SEM. The results show that the catalytic activity of 6NiO/SA is the lowest among the three catalysts. 6NiO/AC has the largest specific surface area and smaller metal grains

showing better catalytic activity than 6NiO/HZSM-5 and 6NiO/SA. Under the conditions of

(CO

(CH

) of 1

the temperature of 900 ℃ and the reaction time of 60 min

the CH

conversion rate and CO

conversion rate are 91.4% and 93.4%

respectively. The stability of 6NiO/AC was investigated under the conditions of

(CO

(CH

) of 1

temperature of 800 ℃ and reaction time of 240 min. It is found that the CH

conversion rate is always maintained at about 70%. After the reaction

the carbon deposition type of 6NiO/AC is mainly filamentous carbon deposition

which ensures the active site of the catalyst. In addition

the introduction of excessive CO

in the reaction system can make the reaction go forward

promote the carbon deposition gasification reaction and inhibit the carbon formation.
