Impacts of Natural Gas on Gas Products of Municipal Solid Waste Pyrolysis

摘要

Simulated municipal solid waste sample is pyrolyzed in natural gas or nitrogen. Gas chromatogram is used to analyze the composition of gas products. The result showed that different atmosphere is impact on different gas product. In the nitrogen, the yields of methane is infinitesimal, and increase with the temperature increasing at low temperature stage (400℃～600℃), while the yields is decrease slightly at high temperature stage (600℃～1000℃). In natural gas, the yields of hydrogen are higher obviously than in nitrogen, especially at high temperature. Natural gas impacts on production of carbon monoxide also.
