微波辐射下活性炭催化甲烷裂解制氢
Microwave-assisted catalytic decomposition of methane over activated carbon for hydrogen production
摘要
Abstract
The microwave-assisted pyrolysis of methane over an activated carbon (AC) was studied in a fixed-bed quartz-tube reactor. The effects of reaction atmosphere,methane partial pressure and iron powder on methane conversion were investigated. The AC showed better microwave heating performance in N2 or H2 atmosphere than that in CH4 atmosphere. Iron powder could promote microwave heating of the AC,leading to higher methane conversion. SEM results indicated that carbon would deposit on the surface of the AC during methane decomposition. The spent AC had lower surface area,lower pore volume,and larger pore diameter than those of fresh ones,which suggested that carbon deposition in the pores caused deactivation of the AC.关键词
