“…Due to the consumption of fossil fuels and the aggravation of environmental pollution, the global environment is deteriorating, which is making the development and utilization of renewable energy become much more significant. A promising porous carbon material derived from biomass with excellent physicochemical property is widely used in the energy storage and conversion field, − such as catalyst, , adsorbent, , electrode material, − etc., aiming for replacing traditional fossil energy. In particular, high-performance supercapacitors attract much attention because of their rapid charge/discharge rates, long cycle lifetime, high power output, etc .…”

The preparation of high-value biochar as a supercapacitor is a promising way for biomass utilization. In this work, a self-activation method was proposed to prepare nitrogen and sulfur co-doping hierarchical porous biochar by using mantis shrimp shell as carbon, nitrogen, and sulfur precursors. The porosity and surface chemical properties of biochar were adjusted upon different temperatures. It was found that the obtained biochar had a dendritic and uniform morphology, in which micro-, meso-, and macropores were interconnected regularly in the structure, and the nitrogen and sulfur heteroatoms were successfully homogeneously introduced into the carbon frameworks. On the basis of electrochemical tests, novel shell biochar with an activation temperature of 750 °C demonstrated the highest specific capacitance, which was 201 F g −1 at a current density of 1 A g −1 in a 6 M KOH electrolyte, due to the large BET surface area of 401 m 2 g −1 , and high nitrogen (8.2 wt %) and sulfur content (1.16 wt %). The in situ template approach from natural biomass provided tremendous potential for the active electrode materials of supercapacitors.

“…The significantly lower wax product of catalytic pyrolysis in all three media provides further evidence that the catalyst would accelerate the cracking reactions. The catalyst accelerated the cracking of wax species and formed larger quantities of organic 18 The different yields of the products in the presence of different carrier gases also indicated that a feature of the carrier gas (such as its molecular weight) could affect the reaction pathway. The lighter carrier gas led to the formation of higher amounts of char, indicating that a heavier carrier could enhance the rate of cracking reactions of char and wax.…”

Polyethylene terephthalate, the main material used for beverage bottle packaging, accounts for an average of 7.6% of all plastic waste in Europe. This material is not biodegradable and takes several centuries to decompose. The pyrolysis process in the presence of a catalyst and carrier gases can convert PET waste into solid, liquid, and gaseous materials that can be utilized as fuel. This study evaluated the effects of different carrier gases on the pyrolysis of PET waste in the presence and absence of a zeolite catalyst (A4). The results showed that the catalyst affected the pyrolysis yield; it increased the liquid and gaseous products, as well as the benzoic acid content. However, the effect declined when replacing the carrier gas with a larger molecular weight carrier gas. The alcohol content of the char was larger than that of the wax. The maximum alcohol content was detected under He, implying the direct impact of the carrier on the pyrolysis products. The hydrocarbons identified in the char were affected by changing the carrier gas, and a different distribution of hydrocarbon groups was found by converting the aromatic group into aliphatic compounds. Broadly speaking, in the presence of helium gas and the catalyst, the lowest amount of coke and the lightest compounds were observed. The amount of coke in the presence of nitrogen gas was the same as that of helium gas, but it had heavier compounds. Meanwhile in the presence of argon gas, which has a high molecular mass, more coke and heavier compounds were obtained. © 2022 Society of Chemical Industry (SCI).

“…Though few studies on the evaluation of the catalytic potential of BC-based catalysts have been conducted in the past, still no studies have been conducted on catalytic pyrolysis of pine needle waste using a nickel-impregnated activated BC-based catalyst. Moreover, the literature revealed that most of the previously carried out studies on BC catalysts, using some other biomass feedstock, do not give comprehensive knowledge on all the aspects of the catalyst effect on the kinetics as well as product distribution, properties, and composition, which is very important from the process commercialization point of view. − A detailed review of BC-based catalysts and their comparison with the current study have been elucidated in section S9, supporting information.…”

The present study highlighted the impact of biochar (BC)-based catalysts on catalytic pyrolysis of pine needle biomass. Thermogravimetric plots showed positive influence of catalysts by indicating reduction in the temperature requirement of the process. The same had also been stated through process kinetics by demonstrating reduction in the process’s activation energy (E a). E a had been reduced from 25.95 kJ/mol in noncatalytic pyrolysis to 20.79, 15.20, 10.52, 13.99, and 9.69 kJ/mol for BC, Ni/BC, Ni/BC-ZnCl2, Ni/BC-H3PO4, and Ni/BC-NaOH catalytic pyrolysis, respectively. Physicochemical characteristics of bio-oil indicated improvement in its high heating value and % deoxygenation achieved during the process. Catalyst incorporation in the process increased the production of phenols as well as aliphatic and aromatic hydrocarbons. The presence of surface acidic functionalities coupled with metallic sites in Ni/BC-ZnCl2, Ni/BC-H3PO4, and Ni/BC-NaOH increased the aromatics selectivity to 35.18, 36.47, and 35.64%, respectively. Similarly, aliphatics were also enhanced to 9.61, 10.12, and 11.68% using Ni/BC-ZnCl2, Ni/BC-H3PO4, and Ni/BC-NaOH, respectively. Also, chemically activated catalysts showed high stability toward deactivation. Thus, low-cost BC-based catalysts can be effectively employed in place of currently utilized high-cost catalysts in the catalytic pyrolysis process, which will help to make the process more integrated and closed-loop.
