“…(4) FeCl 3 could catalyze the dehydration and decarboxylation of PG by coordinating to the oxygen functional groups, thereby promoting the formation of furfural and hydroxymethyl furfural derivatives (Figure S1d). ,, FeCl 3 can also react with melamine (Figure S1e). Due to the complexity of the reactions during the hydrothermal process, mixed phases of NH 4 Cl (JCPDS No.…”

“…The full width at half-maximum (fwhm) of the (002) peak for PC, NPC, PC Fe , and NPC Fe is calculated to be 7.82, 9.77, 7.01, and 7.21, respectively. The NPC Fe and PC Fe samples have much narrower (002) peaks than those of NPC and PC, indicating that addition of FeCl 3 could catalyze formation of graphitic carbon. , The catalytic graphitization of biomass with iron ions may involve two mechanisms. , One is the impregnation of biochar with melted FeCl 2 upon heating and then precipitating as graphitic carbon . The other is formation of carbides from biochar with metal particles and then decomposing at a certain temperature to generate graphitic carbon .…”

Biomass is an abundant, low-cost, renewable, and structurally diverse carbon-rich source, which makes it an intriguing precursor to fabricate diversified carbon materials, whereas it is difficult to control the structure and surface functionality of biomass-derived porous carbons. In this work, a strategy of utilizing in situ-formed FeCl2 as a catalyst, molten salt as a template, NH4Cl as a N source, and a chemical blowing agent to assist in activating, catalyzing, and doping the biomass precursor is proposed to fabricate heteroatom-doped porous carbon NPCFe. The as-prepared NPCFe has a large specific surface area of 1168.5 m2 g–1 with abundant micropores and a high level of N/O-doping content (8.6/7.5 atom %). The NPCFe as an electrode material has a high specific capacitance of 379 F g–1, good rate capability, and excellent cycle stability. The NPCFe-assembled symmetric supercapacitor has a high energy density of 18.9 Wh kg–1 at a power density of 325 W kg–1. This strategy of combining in situ molten salt templating and chemical blowing is promising in preparing high-performance porous carbons for supercapacitor applications.

“…Qi et al used FeCl 3 as a catalyst to increase cotton textile waste conversion to hydrochars, achieving highly efficient hydrophobicity by lowering the hydrothermal carbonization temperature. In addition, the simultaneous impacts of FeCl 3 and hydrothermal carbonization produced a side reaction pathway by allowing more furfural compounds as derivatives [134].…”

The fashion industry contributes to a significant environmental issue due to the increasing production and needs of the industry. The proactive efforts toward developing a more sustainable process via textile recycling has become the preferable solution. This urgent and important need to develop cheap and efficient recycling methods for textile waste has led to the research community’s development of various recycling methods. The textile waste recycling process can be categorized into chemical and mechanical recycling methods. This paper provides an overview of the state of the art regarding different types of textile recycling technologies along with their current challenges and limitations. The critical parameters determining recycling performance are summarized and discussed and focus on the current challenges in mechanical and chemical recycling (pyrolysis, enzymatic hydrolysis, hydrothermal, ammonolysis, and glycolysis). Textile waste has been demonstrated to be re-spun into yarn (re-woven or knitted) by spinning carded yarn and mixed shoddy through mechanical recycling. On the other hand, it is difficult to recycle some textiles by means of enzymatic hydrolysis; high product yield has been shown under mild temperatures. Furthermore, the emergence of existing technology such as the internet of things (IoT) being implemented to enable efficient textile waste sorting and identification is also discussed. Moreover, we provide an outlook as to upcoming technological developments that will contribute to facilitating the circular economy, allowing for a more sustainable textile recycling process.

“…Although the starting biomasses exhibited high HHV values, hydrothermal treatment further enhanced this fuel characteristic for almost 10 MJ kg -1 in the CC-260 and PL-260 samples while about 6 MJ kg -1 in the OP-260 sample. Removal of substances with low HHV such as hemicellulose (13.9 MJ kg -1 ) [28] and cellulose (16.5 MJ kg -1 ) [28] from the biomass during HTC can cause an increase in HHV of the produced hydrochars [1,28]. Furthermore, as the reaction temperature was elevated degradation of structure constituents was accelerated, causing higher HHV.…”

“…Waste biomass is a source that includes different agricultural and forest residues, municipal waste streams, sewage sludge, organic waste, and others. However, the direct application of crude biomass has several disadvantages that include low energetic potential, hygroscopic nature, and release of volatiles during combustion [1,2]. Additionally, high ash content due to the presence of different metals in raw biomass causes corrosion, clogging, and/or clinkers formation in the furnaces.…”

In recent decades, massive exploitation of fossil fuels caused a growing demand for the production of energies from renewable sources. Hydrochar obtained from waste biomass via hydrothermal carbonization (HTC) possesses good potentials as a biofuel. Therefore, we performed HTC of corn cob, paulownia leaves, and olive pomace at different temperatures (180, 220, and 260 oC). The main goal of this study was to comparatively evaluate the influence of HTC conditions on the structure and fuel characteristics of the obtained solids. The results showed that the yields of hydrochar decrease significantly with increasing temperature in all samples. The carbon content and higher heating value increased and reached the highest values in hydrochars obtained at 260 oC, while the content of volatile matter decreased. Furthermore, the Van Krevelen diagram reveals that the transformation of feedstock to lignite-like products upon HTC was achieved. In this study, the results showed that processes of dehydration and decarboxylation during HTC provoke intensive biomass transformation and that hydrochars obtained at higher temperatures have significantly enhanced fuel properties and fewer volatiles compared to the feedstock.
