Abstract

A detailed research of the major influencing factors on hydrogen-rich synthesis gas production during the thermochemical municipal solid waste(MSW) was carried out. The relationship between hydrogen generation characteritics and major factors was investigated. A detailed analysis about the components of MSW was made. MSW was pretreated into refuse derived fuel(RDF) to achieve a raw material with homogenization components for the following gasification experiments. RDF was employed to carry out a series of pyrolysis experiments, gasification experiments and steam gasification experiments at 700, 800 and 900℃, respectively. The experimental results indicate that, by manufacturing MSW into RDF, not only the moisture content can be effectively reduced, but also their low heating value (LHV) can be increased nearly double. It also demonstrates that temperature and steam are key influencing factors, furthermore, it is confirmed that steam supply during gasification will promote hydrocarbons of waste to be decomposed into valuable gas compositions, such as CO and H2. However, temperature plays a dominate role in hydrogen generation. The higher temperature is, the more hydrogen can be achieved. It shows that a kind of synthesis gas containing the highest hydrogen concentration to 34.13% can be generated from steam gasification process at 900℃,and the maximum LHV of gas to 14 509 kJ/Nm3 can be achieved during the pyrolysis process at 800℃.
