The kinetic parameters for the pyrolysis of biomass of the pitch pine (Rigida pine P. Mill) were examined by thermogravimetric analysis in the temperature range 25 °C to 700 °C, in which the main decomposition was occurred from 250 °C to 400 °C. Pyrolysis of pitch pine has been investigated in a bubbling fluidized bed reactor. In this system, silica sand and nitrogen were used as the fluidizing bed material and fluidizing medium, respectively. The experimental was systemically performed on different temperature, fluidized velocity, and particle size of biomass. The optimum temperature condition at which the bio-oil yields reached the highest value (65.5%) was 500 °C. In addition, the higher heating values of bio-oils from pitch pine biomass were reached in the range 22 MJ/kg to 24 MJ/kg. Moreover, this bio-oil had high content of useful chemicals including such as levoglucosan, furfural, and guaiacol. The large amount of C₅–C₁₁ (gasoline fraction) produced make the pyrolyzed oil originating from pitch pine trees a promising biofuel candidate.

在25 °C至700 °C的温度范围内，通过热重分析研究了沥青松（Rigida pine P. Mill）生物质热解的动力学参数，其中主要分解发生在250 °C至400 ° C之间C。已经在鼓泡的流化床反应器中研究了沥青松的热解。在该系统中，硅砂和氮气分别用作流化床材料和流化介质。实验是在不同的温度，流化速度和生物质颗粒大小下系统地进行的。生物油产量达到最高值（65.5％）的最佳温度条件是500     ℃。另外，来自沥青松生物质的生物油的更高的热值达到了22  MJ / kg到24  MJ / kg的范围。而且，这种生物油具有高含量的有用化学物质，包括左旋葡聚糖，糠醛和愈创木酚。大量产生的C ₅ -C ₁₁（汽油馏分）使源自沥青松树的热解油成为有前途的生物燃料候选者。
