摘要

甲烷干重整（DRM）反应能够将CO

和CH

两种主要温室气体高效转化为H

和CO，从而实现资源化利用，具有重要的研究意义。Ni基催化剂因具有成本较低和活性较高的特点备受关注，但易因积炭导致失活，这一问题亟待解决。采用硅溶胶辅助溶液燃烧法制备了具有三维介孔结构的Ni-ZrO

催化剂，并将其应用于低温DRM反应。通过N

吸/脱附、XRD、H

-TPR、TEM和TG-DTA等多种表征手段，系统研究了催化剂结构以及Ni含量（质量分数，下同）和反应温度对催化剂催化性能的影响，并与普通浸渍法及传统溶液燃烧法制备的催化剂进行了对比。结果表明，硅溶胶辅助溶液燃烧法制备的催化剂具有较大的比表面积和稳定的三维介孔结构，并展现出更强的金属-载体相互作用。在催化性能方面，Ni含量对催化剂抗积炭性能和催化活性均具有显著影响。随着Ni含量的增大，催化剂的积炭倾向显著增强。在温度为600 °C、空速为135000 mL/(g·h)下进行20 h低温DRM反应后，具有三维介孔结构的1%Ni-ZrO

-CSC催化剂的CH

和CO

转化率分别维持在31%和38%，

(CO)稳定在0.45，且未观察到积炭生成，表明其具有优异的抗积炭性能。

Abstract

The dry reforming of methane (DRM) reaction efficiently converts two major greenhouse gases

and CH

into H

and CO

thereby achieving resource utilization and holding significant research value. Ni-based catalysts have garnere

d attention due to their low cost and high activity

but their deactivation caused by coking remains a pressing issue. Three-dimensional mesoporous Ni-ZrO

catalysts were prepared by colloidal silica-assisted solution combustion method and applied to low-temperature DRM reaction. Characterizations including N

adsorption/desorption

XRD

-TPR

TEM

and TG-DTA were conducted to systematically investigate the structures and the effects of Ni contents (mass fraction

the same below) and reaction temperatures on catalytic performance of catalysts. Comparisons were made with catalysts prepared via ordinary impregnation method and traditional solution combustion method. The results indicate that the catalysts prepared by colloidal silica-assisted solution combustion method exhibit larger specific surface areas

stable three-dimensional mesoporous structures

and have strong metal-support interactions. Regarding catalytic performance

Ni contents significantly affect both anti-coking performances and catalytic activities. As the Ni contents increase

the tendency of catalysts for coking becomes more pronounced. After a 20 h low-temperature DRM reaction at the temperature of 600 ℃ and space velocity of 135000 mL/(g·h)

the three-dimensional mesoporous 1%Ni-ZrO

-CSC catalyst maintains CH

and CO

conversion rates of 31% and 38%

respectively. The

(CO) stabilizes at 0.45

and no coking is observed

demonstrating 1%Ni-ZrO

-CSC’s excellent resistance to coking.
