Bioproducts from agro-industrial plant residues: opportunities for sustainable reuse / Bioprodutos de resíduos agroindustriais vegetais: oportunidades ao reaproveitamento sustentável

“…Brazilian Journal of Development, Curitiba, v.7, n.9, p. 89356-89381 sep. 2021 Sugarcane, given the large number of reports, proves to be an agronomic crop with great potential for the development of bioproducts (Bernardino et al 2018;Ullah et al 2019;Solorzano-Chavez et al 2019;Grewal and al.

A Review of Intermediate Pyrolysis as a Technology of Biomass Conversion for Coproduction of Biooil and Adsorption Biochar

“…It has also been proved that intermediate pyrolysis of rice straw wastes proved to offset carbon dioxide than the rest of types [32]. Other intermediate pyrolysis studies on wastes such as organic fraction of municipal solid wastes [12], sugarcane bagasse [127], sugarcane bagasse and oat hulls [128], chicken manure for fertilizer and heat production [5], wheat husk [27], waste tires [129], and Bambara groundnut shells [24] have appreciated the advantages of intermediate pyrolysis. ese good results indicate the effectiveness of intermediate pyrolysis on the conversion of wastes when compared to current common technologies.…”

Deoxygenation of Bio‐oil from Calcium‐Rich Paper‐Mill Waste

“…However, it should also be noted that increasing the reforming temperatures promotes cracking reactions to produce higher yields of syngas at the expense of liquids [46]. Santos et al [22] reported that the bio-oil yields of sugarcane bagasse and oat hulls are improved by running the TCR system at lower reforming temperatures (500, 600, and 700°C) which reduce the enhanced cracking of organic vapors. Furthermore, TCR makes a better separation between the water phase and organic phase of the pyrolysis liquid, and this is the reason why the HHV of TCR oils are higher than fast-pyrolysis oils [23,47].…”

“…Thermocatalytic reforming (TCR) is a technology that combines intermediate pyrolysis and high-temperature reforming of volatiles in a single processing system. The organic vapors undergo cracking and reforming, and this results in bio-oil with improved physicochemical characteristics [22,23].…”
