摘要
Abstract
Microwave-assisted catalytic rednctive dechlorination on Raney Ni-Al alloy
catalyst is an efficient method for chlorobenzene (CB) and
1,4-dichlorobenzene (1,4-DCB) treatment. The result showed that the Raney
Ni-Al alloy catalyst retains its high activity in this in-situ reductive
dechlorination reaction. This reductive dechlorination reaction was in
accordance of the psendo-second-order reaction kinetics under microwave
irradiation. The activation energy (Ea) was 76.24 kj/mol. And the constant
of 1,4-DCB dechlorination was 0.037 6 (35 ℃ ) and 0.151 mol/(L · min) (50
℃) , and the activation energy (Ea) was 76. 66 kj/mol. Rapid and complete
dechlorination which was achieved for CB and 1,4-DCB was obtained at close
to ambient conditions. And it was showed that microwave-assisted catalytic
in-situ reductive dechlorination on Raney Ni-Al alloy catalyst was an
effective method to rapid and complete dechlorination for polychlorinated
organic compounds.关键词
