Special Issue Information

Dear Colleagues,

The purpose of this Special Issue, “State-of-the-Art of Sustainable Biofuels from Waste and Biomass in Brazil”, is to present a collection of scientific manuscripts focusing the recent advances in the thermochemical conversion of biomass and waste into liquid and solid energy fuels and chemicals in Brazil. Topics of interest include, but are not limited to: biofuels production processes (pyrolysis, catalytic cracking, homogeneous and heterogeneous transesterification); biosolids and chemicals production processes (pyrolysis, hydrothermal carbonization and liquefaction); catalysts for the production of biofuels and chemicals by thermochemical conversion of biomass residues; simulation of bio-oil and biofuels fractionation and deoxygenation (distillation, liquid–liquid extraction, absorption, adsorption, etc.) using chemical process simulators; biomass pretreatment and activation to produce bio-oils and bio-adsorbents by thermochemical processes (pyrolysis, hydrothermal carbonization and liquefaction); thermochemical conversion of municipal household solid wastes and sewage sludge (pyrolysis, catalytic cracking, hydrothermal carbonization and liquefaction); thermochemical conversion of plastics and polymeric residues (pyrolysis, catalytic cracking); tecno-economic analysis of biofuels production processes (pyrolysis, catalytic cracking, homogeneous and heterogeneous transesterification).

Abstract

Decarbonization of the aviation sector relies on deployment of sustainable aviation fuels (SAF) at commercial scale. Hydrothermal liquefaction (HTL) has been recognized as a promising technology to help supply the increasing projected SAF demand. High availability of agro-industrial residues, combined with a well-established biorefinery system, makes the sugarcane industry in Brazil a good option for HTL technology deployment. Moreover, challenges regarding the economic feasibility of SAF from HTL could be partially addressed by the RenovaBio policy, a market-driven incentive mechanism of carbon credits implemented in Brazil. This study investigated both the techno-economic and life cycle assessment of SAF production from sugarcane lignocellulosic residues, considering HTL integrated to a first-generation ethanol distillery and a HTL stand-alone facility. The evaluated scenarios showed great climate mitigation potential, reaching a reduction of up to 73–82% when compared to fossil jet fuel. The minimum fuel selling price of SAF at 15.4 USD/GJ indicated potential of economic competitiveness with fossil jet fuel in the best integrated scenario. The economic benefits obtained from carbon credits are not enough to enable feasibility of HTL in the stand-alone scenarios, even with carbon prices projected at 125 USD/tonne CO₂-eq avoided.

Abstract

Solar pyrolysis is a promising technology as it combines use of biomass and solar energy to generate transportable and storable fuels, as well as chemicals of interest. The most desired product of rapid pyrolysis of microalgae is bio-oil, a liquid and viscous mixture composed of hundreds of chemicals. Among these compounds are many oxygenates that usually bring some undesirable properties to bio-oil, e.g., instability. This study aimed to investigate the potential of Spirulina platensis to produce bio-oil from catalytic solar pyrolysis assisted by Fresnel lens. The performance of the mixed oxides derived from hydrocalumite was evaluated, aiming to improve the yield and quality of the liquid product. The effects of reaction time and percentage of catalyst on the product distribution and bio-oil composition were quantified. An optimization study was performed using the differential evolution (DE) algorithm in order to maximize the bio-oil yield. The results showed that the highest liquid yield (43.4%) was obtained in 23.4 min using a catalyst percentage of 58.6%. The mixed oxides derived from hydrocalumite contributed to the improvement in the bio-oil quality, which presented in its composition a low quantity of oxygenated compounds and a higher percentage of hydrocarbons.

Abstract

This work aims to investigate the influence of temperature and chemical impregnation in the textural and morphological composition of the bio-adsorbent of bio-adsorption via thermal cracking of the seeds of açaí. The experiments were carried out at 400 °C and 450 °C using a pilot scale reactor. The efficiency of the organic process was calculated in terms of liquid and solid products selected with a chemical impregnation process with NaOH, mainly with the liquid that had a greater product conversion. The elementary samples of the solid products occur with the occurrence of carbonization with an increase in the temperature of the process and the presence of impregnation. The textural and morphological characterization occurred with an analysis of FT-IR, SEM/EDS, XRF, and B.E.T. The in-phase product was developed through the creation of açaí seed in nature and impregnated with NaOH solution (2 M) at temperatures of 400 °C and 450 °C. The adsorption kinetics of acetic acid were investigated at 5, 10, 15, 20, 60, 120, and 180 s. The adsorption is higher at 450 °C and with the chemical impregnation of NaOH since the experiments were able to remove an amount of 317.51 mg acid/g adsorbent acetic acid. All the models analyzed fit the experiments, both for the kinetic models (pseudo-first order and pseudo-second order) and for the equilibrium models (Langmuir and Freundlich). Full article
