The pyrolysis technology of wastes occupies an important position in solid waste disposal due to its lower secondary pollution and higher recovery rate of energy.After the refuse derived fuel(RDF) is prepared from residual wastes through pressing

a pyrolysis test of RDF has been carried out.Results of test show that the plastics

CaO

and DHC-32 added into RDF is helpful to enhance the temperature of pyrolysis

and can significantly improve the progress of fuel pyrolysis reaction and the efficiency of prolysis

at the same time

the content of K and Na in the carbocoal has remarkable tendency to change in case the test condition being varied.
