“…Thus, we can reach the conclusion that functional biochar has been enhanced oligomerization reactions to produce olefins and aromatic hydrocarbons. These results were in agreement with our previous studies regarding catalytic pyrolysis of biomass [8,13].…”

“…In the condenser, the condensable gases condense to bio-oil and uncondensable gases enter to the columned columns that already filled with the saturated brine sodium chloride. Then, condensed pyrolysis oil was collected and analyzed by GC/MS and syngases (uncondensable gases) in the columned columns were analyzed by gas chromatography after the volume notes [13]. Preparation method of functional and Fe composite biochars is described in the literature [6].…”

This study investigated the behavior of two types of modified biochar (functional and iron composite biochars) as a catalyst regarding their surface chemistry and morphological properties and their effects on bio-product derived from pyrolysis of Cladophora glomerata (C. glomerata) macroalagae. Two catalytic pyrolysis experiments were conducted in 25 mL slow pyrolysis reactor in the presence of biochar-based catalysts at the temperature of 500 °C. For functional biochar, no clear effect on biogas production was observed, whereas iron composite biochar increased the hydrogen content by 7.99 mml/g algae. Iron composite biochar with a 3D network structure demonstrated remarkable catalytic behaviors (especially toward hydrogen production) due to its wonderful surface area, high dispersion of iron particles and particular structures and compositions. The biochar derived marine biomass and treatment process developed here could provide a promising path for the low-cost, efficient, renewable and environmental friendly catalysts.

“…With the increase of environmental pollutants of industrial or agricultural activities, the excessive blooming of macroalgae has become a serious problem in coastal areas worldwide, not only they are harmful to the health of human beings through providing adequate conditions for bacterial growth but also can adversely affect tourism via destroying the beaches. , Therefore, substantial efforts have been focused on marine macroalgae for use as an energy crop or feedstock for the biorefinery. , For instance, Norouzi et al showed that despite the negativism related to the adverse ecological effects of marine green macroalgae, it could be a valuable source for hydrogen-rich gas and phenol production via conventional thermochemical processes. , However, in pyrolysis of macroalgae, in addition to the biofuels and valuable chemicals, a large amount of carbon-rich, porous solid called algal biochar is also obtained . The unique physical and chemical properties of algal biochar make it applicable to a variety of research and practical applications .…”

Via the activation treatment on Cladophora glomerata (CG) with FeCl 3 and KOH, magnetic biochar (MBC) with olive-shaped pores and functional biochar (FBC) with a novel interconnected 3D pore network structure have been successfully prepared by a facile slow pyrolysis process to be applied as electrodes in supercapacitors. To obtain Fe composite biochar (FCBC), FBC was functionalized with HNO 3 and H 2 SO 4 for extending formation of iron oxide through the hydrothermal method. These electrodes demonstrate remarkable electrochemical behaviors, in terms of wonderful rate capability, high specific capacitance and excellent cycle stability when first served as electrodes for supercapacitors. In addition, we have successfully fabricated an asymmetric supercapacitor with high energy and power densities using FBC as the anode electrode and iron oxide/ carbon composites (MBC and FCBC) as the cathode electrodes in a neutral aqueous 3 M KCl electrolyte. Because of the desirable porous structure, high specific capacitance, rate capability, and complementary potential window of the two electrodes, the asymmetric supercapacitor can be cycled reversibly in a wide potential window of 0−1.8 V and exhibits energy density 41.5 Wh kg −1 at a power density of 900 W kg −1 for FBC//FCBC. The asymmetric supercapacitor also presents stable cycling performance with 93.1% for FBC//FCBC capacitance retention at 8 A g −1 after 10000 cycles. These encouraging results show great potential in developing energy storage devices with high energy and power densities for practical applications.

“…Sabegh et al [58] produced a multi-metal oxide catalyst (mainly Al 2 O 3 , CeO 2 , and AuO 2 et al) from the catalytic converter of a spent car for the pyrolysis of the C. glomerata. The results showed that the main function of the catalyst is deoxidizing nitrogenous compounds, promoting ketonization reaction, converting acid to ketone, and thus reducing the corrosiveness of the bio-oil.…”

The disposal and use of natural algae have recently been the subject of great interest, due to increasing concern for environmental protection and resource utilization. In this paper, a mini review of recent research on the pyrolysis of natural algae, especially the algae from water blooms, is presented. The chemical compositions of the natural algae are summarized, and the pyrolysis properties of different compositions are reviewed. Non-catalytic, catalytic, and integrated catalytic processes are reviewed. Different ideas and methods for the production of bio-fuel or chemicals are discussed. Apparently, deoxygenation and denitrogenation are highly necessary for algae-based bio-fuel and catalysts play an important role in these processes. In addition, the integrated catalytic process, which involves catalysis and other operation conditions aside from the thermal treatment under inert atmosphere, shows potential for the valorization of algae-based bio-oil. Based on the recent concept and progress, the research gaps are discussed, followed by the challenges and proposals to achieve high-value utilization of the natural algae.
