Pyrolysis Experiment of Refuse Derived Fuel and Study on Characteristics of Semi-Coke

The experimental material is source-separated municipal solid waste. Remaining waste from primary assortment is compressed into RDF with mechanical molding equipment. We used high-temperature tube furnace for pyrolysis experiment of RDF. The effects of pyrolysis temperature, material composition, choice of additives and the content of the additive on the productivity of pyrolysis for these samples were investigated; the variation trend of content for K and Na elements in semi-coke was analyzed under various factors. The results show that adding plastics, CaO or DHC-32 is conductive to improve the effect of RDF pyrolysis. Increasing pyrolysis temperature is in favor of the process of pyrolysis reaction, meanwhile, the apparent variation trends are presented for the content of K and Na in semi-coke under the various experimental conditions.
