| 摘 要： | INTRODUCTION Bark accounts for 10% of a log and there are about 2.5 billion m3 of logs consumed every year all over the world, which produce 250 million m3 of bark. It will bring a huge amount of money if we make good use of the bark as a raw material of industry. Since middle- and small- diameter classes wood of poor quality and remnant products account for an important part of forest resource, we should advance comprehensive utilization energetically and orient it to whole-tree utilizati…

| Abstract: | 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. |
