摘要：
Gas production and analysis from pyrolysis of municipal solid waste (MSW) with zeolite and calcined dolomite as catalyst has been investigated in a downstream fixed-bed reactor over the temperature range of 200-750 degrees C. Gas production from pyrolysis of MSW varied in the range of 49-57 mol%. The results indicated the presence of calcined dolomite influenced significantly the product yields and gas composition in pyrolysis process, and revealed essential catalytic performance on increasing gas yield and decreasing oil yield and char yield comparing to zeolite and non-catalytic process. A higher temperature 600-750 degrees C resulted in a higher conversion of MSW into gas production with a greatly increasing of CO contents. Consequently, CO is a key factor to produce renewable energy and bio-gases (syngas and methane). (C) 2014 Elsevier B.V. All rights reserved.
