“…The fractionation or yield of the pyrolysis products is determined by the operational factors of the equipment and the nature of the biomass. The operational variables that most influence the conversion are the reactor type, biomass diameter, temperature, heating rate, process operating time, and inert gas flow [71]. Pyrolysis can be classified as slow, fast, or flash, depending on the operating variables, particularly the working time and heating rate [72].…”

Sugarcane has primarily been used for sugar and ethanol production. It creates large quantities of residual lignocellulosic biomass such as sugarcane bagasse, leaves, tops, and vinasse. Biomass is a sustainable prospect for biorefineries aiming to optimize production processes. We detail recent research developments in recycling sugarcane, including energy generation and pyrolysis to obtain biofuels, for example. To produce biochar, the energy cost of operating at high temperatures and large-scale production remain as obstacles. The energy generation prospects can be enhanced by pellet production; however, it requires an improvement in quality control for long-term storage or long-distance transportation. In civil construction, the materials still need to prove their long-term efficiency and reliability. Related to adsorbent materials, the use of sugarcane bagasse has the advantage of being low-cost and environmentally friendly. Nevertheless, the extraction, functionalization, and modification of cellulose fibers, to improve their adsorption properties or even mode of operation, still challenges. The synthesis of nanostructures is still lacking high yields and the ability to scale up. Finally, controlling dispersion and orientation and avoiding fiber agglomeration could improve the mechanical response of composites using sugarcane bagasse. The different possibilities for using sugarcane and its residues reinforce the importance of this material for the industry and the global economy. Thus, the present work addresses current challenges and perspectives of different industrial processes involving sugarcane aiming to support future research on waste-derived subjects.

“…This gives detailed information on how the reactor works. In an earlier study, 41 the monitoring and control system was tested in a fast pyrolysis reactor with sugarcane bagasse for more than 70 h of continuous operation. The fuel feeding rate may be precisely controlled, using the technology to maintain the reactor operating temperature and produce pyro gas of consistent quality.…”

A rotary screw pyro-oil reactor was designed for powdery biomass for a feeding capacity of 40 kg h −1 with a moisture content of <10%. The pyro-oil reactor temperature was maintained at 450-550 °C. The pyro-oil vapors produced were quickly drafted out of the reactor for quenching to yield 16-24 L h −1 from 40 kg h −1 of biomass feed. The flash-pyrolysis technique, which is capable of directly turning biomass into a liquid fuel, was used to produce liquid fuel (bio-oil). It was carried out at a pressure at 0.03 bar and at a medium temperature of about 550 °C. The flash-pyrolysis technique converts the entire biomass matter, excluding the ash. In this method the powdery biomass is converted into three components: bio-oil (the yield is typically 70% on an energy basis, a powdery biomass feed at a moisture content of 10%); pyrolysis gas (typical yield 14%) and char (typical yield 16%). The temperature of the fixed bed was adjusted in the experiment, but the other variables remained constant, such as the amount of feed, the pyrolysis time of the gas product, the reactor pressure and the bed height. A biomass particle size range of 1-3 mm and a biomass residence time of 20 s in the reactor resulted in optimal bio-oil production of 70%. This work demonstrated how precise pyrolysis mechanism processes and bio-oil yields can influence the maximal reaction temperature in the 450-550 °C range. The performance analysis reveals that the fixed bed reaction temperatures of biomass rapid pyrolysis give reliable control over the bio-oil reactor type and size. This paper provides an overview of the design and thermochemical liquefaction process used to convert powdered biomass to biofuel.

“…The sample was dropped into the reactor through a screw feeder after achieving the target temperature in the reactor. The reactor was connected to a condensation system to condense and collect the bio-oil, as described in a previous study [4,5].…”

“…Similarly, the yield of bio-oil increases with the rate of heating until it reaches the maximum value, and then the effect is negligible. Biomass size is also a major parameter as smaller particles will lead to a more uniform heating [4,5].…”

Sugarcane bagasse pyrolysis in a fixed-bed reactor has been studied. The Pyrolytic oil and char obtained were characterized to determine their feasibility as fuels and chemical reagent in other processes. The runs were performed under the following conditions: temperature from 350°C–600°C, sample size of 0.5–1 mm, and an inert gas flow rate of 200 cm3/min. The study aimed to characterize the obtained oil and char to determine their feasibility as source of energy and chemical product. The product has been characterized by different techniques including gas chromatography–mass spectrometry (GC–MS), Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDX). The obtained bio-oil exhibited a molecular formula of CH1.03O0.28 N0.012 and a higher heating value (HHV) of 27.68 MJ/kg. These results indicated that it could be used after refining as a source of fuel and produced a chemical product. In addition, the obtained biochar (HHV = 31.53 MJ/kg) can be used as a solid fuel.
