The objective of this work was to evaluate the influence of the oxygen percentage, heating rate, and total gas flow variables in the pyrolysis process of sugarcane straw through thermogravimetric (TG) and differential scanning calorimetry (DSC) analyses. The experimental conditions of oxygen percentage, heating rate, and total gas flow were optimized using the design of experiments and canonical analysis. The investigated conditions show that to optimize the whole pyrolysis process, the best values for carrying out the process are oxygen concentrations and heating rates around the central level of 10%, and 298 K/min, respectively, where the total gas flow, within the studied constrains, was not statistically significant for the pyrolysis process, according to the regression equations. This condition resulted in approximate values of required heat and percent residual residue of 181.74 kJ/kg and 9.89%, respectively. In addition, the percentage of remaining residue decreases as the heating rate decreases and the percentage of oxygen in the gas mixture increases. The optimum oxygen percentage obtained was also validated by carrying out an autothermal fast pyrolysis in a pilot plant scale.

这项工作的目的是通过热重法（TG）和差示扫描量热法（DSC）分析评估甘蔗秸秆热解过程中氧气百分比，加热速率和总气体流量变量的影响。使用实验设计和规范分析优化了氧气百分比，加热速率和总气体流量的实验条件。研究的条件表明，要优化整个热解过程，进行该过程的最佳值是氧气浓度和加热速率，分别在中心水平10％和298 K / min左右，其中根据回归方程，研究的约束条件对热解过程没有统计学意义。此条件导致所需热量和残余残留物百分比的近似值分别为181.74 kJ / kg和9.89％。另外，随着加热速率的降低和气体混合物中氧气的百分比的增加，残留残留物的百分比降低。还通过在中试规模内进行自热快速热解来验证获得的最佳氧气百分比。
