With the self-made pyrolysis equipment in miniature, we experimented in different pyrolysis conditions to get different pyrolyzate yields ( carbon, vinegar and gas). It proved that with the rise of temperature, the average yield of carbon descends gradually while the yields of vinegar and gas rise gradually. As the temperature rises, the yield of gas increases much more than that of vinegar. When speeding up the rising temperature, yield of carbon goes down while yields of vinegar and gas go up.
