“…With these results in mind, the same group obtained higher hydrogen production (96.7%) with a maximum glycerol 3 conversion of around 99%, using a different MW power, and a NiZ-Ca50 catalyst. 111 This better hydrogen selectivity was achieved at 600 W MW power, and loads of 20% NiO and 50% CaO, respectively, in zeolite. The study reports that the NiO/ zeolite-CaO catalyst appears to be a superior competitor for hydrogen production by MW irradiation of aqueous solution of triol 3 compared to those in the aforementioned studies.…”

“…The introduction of Ca 2+ changed the internal structure of the catalyst to some extent, which promoted the interaction between the carrier and Ni. Consequently, the yield of H 2 was increased [51,52]. When Mg was introduced into Rh/β zeolite, Rh clusters from the atomic level to the sub-nanometer scale were formed in microporous channels.…”

“…have designed Cu2O@TiO2@ZIF-8, where an internal electric field was formed du p-n junction, which promoted the transfer of electrons to the conduction ba photoelectrons generated from TiO2 were transferred to the conduction band and transferred through ZIF-8. The water can be therefore reduced by these photoelec shown in Figure 8) [52]. To provide more proton sources and active sites, Na + /K + / be added into zeolite, which consequently promotes the hydrogen evolution rate In addition to ethanol, methanol can also be used as the raw material for hydrogen production, that is, methanol steam reforming (MSR).…”

Zeolites are porous materials with plentiful and adjustable pore structures, which are widely applied in various fields such as fossil fuel energy conversion, preparation of clean energy, chemical product conversion, CO2 capture, VOC treatment, and so on. Zeolites exhibited advantageous adsorption compared with traditional adsorbents such as activated carbon; in addition, they can also provide abundant reaction sites for various molecules. The chemical composition, structural acidity, and distribution of pore size can distinctly affect the efficiency of the reaction. The modification of zeolite structure, the development of novel and efficient preparation methods, as well as the improvement of reaction efficiency, have always been the focus of research for zeolites.

“…Actual statistics and severe forecasts on the future demand for fossil resources (even though their usage has led to environmental concerns) testify to the need for more sustainable energy, industrial, and agricultural policies, prompting researchers to seek cleaner energy sources [1][2][3]. The primary objective of the renewable energy program is to increase environmentally favorable energy production by applying innovative technology [4][5][6]. As the demand for renewable energy increases, biomass has emerged as a crucial renewable energy source with a good reputation due to its availability and carbon neutrality.…”

This research aims to evaluate the influence of pyrolysis time and temperature on the composition and properties of bio-oil derived from Mimusops elengi. Experiments were conducted by varying the pyrolysis temperature and time from 400 to 600 °C and 30 to 120 min, respectively. Both pyrolysis temperature and time were found to significantly influence the bio-oil composition. At enhanced pyrolysis temperatures, the bio-oil yield increased while the ash and gas yields decreased. In addition, extended pyrolysis time produced a greater bio-oil yield, indicating that higher temperatures and longer durations promote additional decomposition of biomass. Functional groupings, including alcohols, phenols, ketones, esters, and aromatic compounds in the bio-oil, were identified via FT-IR analysis, indicating that the bio-oil’s diversified chemical properties make it a potential alternative feedstock. GC-MS analysis identified 26 chemical compounds in the bio-oil, of which phenol was the most abundant. However, a high phenol content can diminish bio-oil quality by enhancing acidity, decreasing heating value, and encouraging engine corrosion. Temperature and pyrolysis time are crucial factors in producing bio-oil with the desired chemical composition and physical properties. The maximum yield, 34.13%, was attained after 90 min of operation at 500 °C. The characteristics of the Mimusops elengi bio-oil produced, namely density, viscosity, pH, and HHV were 1.15 g/cm3, 1.60 cSt, 4.41, and 19.91 MJ/kg, respectively, in accordance with ASTM D7544. Using Mimusops elengi as a pyrolysis feedstock demonstrates its potential as an environmentally friendly energy source for a variety of industrial and environmental applications. The yield of bio-oil produced is not optimal due to the formation of tar, which results in the blockage of the output flow during the pyrolysis process.
