摘要：

The aim of this work was to develop a pyrolysis process for polyphenols fraction bio-oil, produced by fast pof Larix gmelinii circulated-fluidized bed (SCFB). This paper is focused on the process examination and product analysis. A range of operating parameters, including temperature (T) from 500 C to 600 C in the SCFB, and particle size (d) from 0.2-0.3 mm to 0.9-1.2 mm, and feed rate (n) from 20 r . min(-1) to 50 r . min(-1), and gas flow (Q) from 15 m(3).h(-1) to 30 m(3).h(-1) in the SCFB was conducted to the effect on the content of phenolic compounds (COP) bio-oil derived from Larix gmelinii. determined that the order of the parameters to influence on the COP in bio-oil was T > d > n > Q. The temperature and particle size of the parameters played key roles in the process. The operating parameters for increasing the COP of bio-oil were determined, i.e. temperature 550 degrees C, particle size 0.3-0.45 mm, feed rate 50 r . min(-1) and gas flow 15 m(3) . h(-1).
