What is oxidative torrefaction?
Oxidative torrefaction, along with non-oxidative torrefaction, is a mild pyrolysis process usually carried out between 200 and 300 °C aiming to increase energy content, the hydrophobicity, and grindability of biomass. Pursuing advances in the torrefaction treatment for energy cost-saving, torrefaction can be performed with flue gases containing a limited amount of oxygen. In these conditions, torrefaction has a higher reaction rate, thereby shortening the torrefaction duration. Moreover, it has been shown potassium catalysis the component's conversion mechanisms during thermal degradation. Therefore, the present study evaluated the combined effect of potassium impregnation and flue gas atmosphere on the torrefaction process. Demineralized woody biomass (Amapaí-Brosimum potabileDucke) samples were impregnated with diff erent concentrations of K 2 CO 3 (0.003M, 0.006M and 0.009M). Oxidative torrefaction was conducted at 275 °C in a laboratory fixed-bed reactor under a flue gas atmosphereup to an anhydrous weight loss (AWL) of 25%, and condensable species were recovered and analyzed by GC-MS. Isothermal TGA at 275 °C was also performed. The combined impact of oxidative atmosphere and potassium impregnation was evaluated by the material reaction kinetics (TG and DTG) and the released condensable. The synergistic behavior of the oxidizing atmosphere and biomass potassium concentration were explored by three indexes, namely the torrefaction severity index (TSI), the catalytic effect area (CEA), and the catalytic index (CI). The potassium addition anticipated the oxidation to early torrefaction times and the oxidative atmosphere enhanced the potassium catalytic effect of increasing the maximum reaction rates during torrefaction. The TSI values enable a dimensionless parameter to calculate the CI. A strong linear correlation (R 2 > 0.90) between CI and K% was evidenced. CI values were 0-0.17. The increase in furfuryl alcohol production with increasing K contents was promoted in the presence of oxygen. Under oxidative conditions, vanillin and syringaldehyde yields decreased with increasing K contents, whereas negligible effects were detected in nitrogen. Results suggest that the residence time and the production of targeted condensable compounds could be adjusted according to the biomass potassium content and torrefaction atmosphere.
What are agricultural residues?
Agricultural residues are considered abundant raw materials that can be used to produce valuable chemicals like furfural. Currently, furfural production is characterized by extensive use of energy and low conversions. However, these challenges can be overcome through process intensification in conjunction with a suitable process synthesis. This work proposes the synthesis, design and optimization of furfural production processes using different intensified distillation and pretreatment alternatives. The eco-indicator 99 and total annual cost were considered as metrics to evaluate the performance of furfural processes. To determine the influence of biomass type on energy, costs and environmental impact, four different biomasses are considered raw materials. The design and optimization of furfural processes were carried out using a two-step procedure. Firstly, all possible alternatives were simulated using Aspen Plus, then the best process option for each biomass is optimized using the differential evolution with tabu list method. The results indicate that a dilute acid pretreatment combined with a thermally coupled scheme provides the lowest cost and environmental impact for all feedstocks. Finally, the optimization results show that the best furfural process consists of wheat straw, dilute acid pre-treatment and thermally coupled distillation, owing to its lowest cost and environmental impact which are 13,092,504 dollars/year and 4,536,512 eco-points/year respectively.

How can biomass waste be used to make furfural?
High availability of biomass waste that is unutilized can become valuable furfural through pyrolysis. Rice straw and oil palm empty fruit bunch have huge potential due to their amount and composition, in which both biomasses contain more than 50% of cellulose and hemicellulose. This work aims to investigate the effects of pyrolyzing biomasses mixture to produce furfural, therefore creating a more flexible process of waste treatment using pyrolysis without waste segregation. This research's objective is to analyze the furfural produced by pyrolysis with an inert gas flow rate between 85-90 mL/minute, a variation of biomasses mass ratio up to a total of 2.5 gram, and also a variation of operating temperature from 450-550°C. The results show that co-pyrolysis of biomass mixture does not affect the conversion, furfural mass, and activation energy significantly (<15%), compared to individual biomass pyrolysis. Furthermore, the research shows that pyrolysis does not undergo significant mass reduction after 35 minutes. The optimum temperature for the production of furfural is 500°C.
