“…The bio-oil yield obtained by using ZSM-5 was found to be 45.60%. Similar results were reported by Maisano et al [37] during CFP of the Mediterranean Sea plant by using ZSM-5. Contrary to the bio-oil, the biochar yield increased with the use of catalysts.…”

Fast pyrolysis is an attractive way of converting abundant biomass resources into valuable products such as bio-oil. Nevertheless, high oxygenated compounds and water content of bio-oil limit its direct use as fuel or chemicals. Catalytic fast pyrolysis (CFP) is able to improve bio-oil properties so that downstream upgrading processes can be economically feasible. In this study five different catalysts such as zeolite socony mobil-5 (ZSM-5), cerium dioxide (CeO2), zirconium dioxide (ZrO2), zinc oxide (ZnO), and sodium carbonate (Na2CO3) were employed due to their potential in enhancing bio-oil properties. CFP of pearl millet (PM) and Sida cordifolia (Sida) was performed to investigate the effects of catalysts on the products distribution and chemical contents of bio-oil. The results showed that bio-oil yield decreased during CFP regardless of catalyst and biomass types. Among all catalysts, CeO2 was found to be the most suitable to produce acids and alkanes from CFP of PM; and acids, ketones, and aromatics from CFP of Sida. The high production of ketones from PM and alkanes from Sida was observed with Na2CO3 catalyst. The ZrO2 catalyst indicated the high aromatics production from PM, whereas alcohols, amines, and others were abundant in bio-oil from CFP of PM using ZSM-5. Overall, PM and Sida can be used to produce fuel or value-added chemicals through CFP.

“…Such a loss of functional groups results from the formation of a fused ring structure that aids in pore formation, by-producing volatile products like CO, H2O, and CO2 [83][84][85]. Removal of hydrogen (H) and oxygen (O) from the precursor during the chemical activation process leads to aromaticity development [86][87][88]. On the other hand, the formation of cyanide during alkaline activation is responsible for the loss of nitrogen (N) content in the ACs [77].…”

Hydrogen (H2) is largely regarded as a potential cost-efficient clean fuel primarily due to its beneficial properties, such as its high energy content and sustainability. With the rising demand for H2 in the past decades and its favorable characteristics as an energy carrier, the escalating USA consumption of pure H2 can be projected to reach 63 million tons by 2050. Despite the tremendous potential of H2 generation and its widespread application, transportation and storage of H2 have remained the major challenges of a sustainable H2 economy. Various efforts have been undertaken by storing H2 in activated carbons, metal organic frameworks (MOFs), covalent organic frameworks (COFs), etc. Recently, the literature has been stressing the need to develop biomass-based activated carbons as an effective H2 storage material, as these are inexpensive adsorbents with tunable chemical, mechanical, and morphological properties. This article reviews the current research trends and perspectives on the role of various properties of biomass-based activated carbons on its H2 uptake capacity. The critical aspects of the governing factors of H2 storage, namely, the surface morphology (specific surface area, pore volume, and pore size distribution), surface functionality (heteroatom and functional groups), physical condition of H2 storage (temperature and pressure), and thermodynamic properties (heat of adsorption and desorption), are discussed. A comprehensive survey of the literature showed that an “ideal” biomass-based activated carbon sorbent with a micropore size typically below 10 Å, micropore volume greater than 1.5 cm3/g, and high surface area of 4000 m2/g or more may help in substantial gravimetric H2 uptake of >10 wt% at cryogenic conditions (−196 °C), as smaller pores benefit by stronger physisorption due to the high heat of adsorption.

“…The existence of an amorphous area might be caused by the deposition of coke over the surface of the OH char. 78 Similar X-ray diffraction to that of SB raw and SB char was indicated in the Varma and Mondal 53 research, while Paschoal et al 88 presented an XRD graph identical to that of the OH raw material, as shown in Figure S6. Within the literature review, any XRD graph related to OH biochar was not found.…”

Catalytic pyrolysis is a complex system where the selection of an efficient, cheap, abundant, and stable catalyst is vital to upgrade pyrolysis products to biofuels. Steel slag (SS) can be considered as an inexpensive catalyst, making it a very economical option. SS has a high content of calcium, iron, and magnesium, making this solid compound catalytically active. This study investigated the utilization of SS as a sacrificial catalyst in pyrolysis experiments using a thermocatalytic reforming (TCR) process to produce an upgraded bio-oil and syngas. In the first part of this work, SS was mixed with sugarcane bagasse (SB) and oat hulls (OH) biochar (in different trials) in the postreformer at different ratios (0, 30, 70, and 100 wt % of SS). In the second part, SS (powder) was pelletized directly with raw OH at different ratios (0, 10, 20, and 30 wt % of SS in the feed composition) and introduced into a pyrolysis reactor. The introduction of SS into SB in the reformer improved the higher heating value (HHV) from 29.1 MJ/kg (0 wt % of SS) to 35.5 MJ/kg (100 wt % of SS). Introducing 30 wt % of SS into OH in the feed showed a higher calorific value and lower acidity, viscosity, and density in comparison with using SS with different ratios in the reformer. The use of SS as a catalyst was found to significantly improve the quality and the properties of bio-oil and syngas, revealing an innovative pathway for its use as an inexpensive sacrificial catalyst for biofuel production via the TCR process.
