“…On the other hand, the study of Wang et al explored the corn stalk performance of the wet torrefied sample's performance in biomass pyrolysis polygeneration, wherein the fixed-bed reactor was employed, and which had biochar as the output product. Aside from the above-mentioned, all the studies shown in Table 2 appear to have resembling analytical methods, which largely involved moisture, organic matter, and ash content, with very few exceptions [15,25,52,54,60,65,83,[88][89][90][91][92][93][94][95][96][97][98][99][100][101][102][103]. Palamanit and colleagues used an agitated bed pyrolysis reactor to examine the yields and characteristics of pyrolysis products obtained from oil palm fronds, trunks, and shells.…”

Pyrolysis and related thermal conversion processes have shown increased research momentum in recent decades. Understanding the underlying thermal conversion process principles alongside the associated/exhibited operational challenges that are specific to biomass types is crucial for beginners in this research area. From an extensive literature search, the authors are convinced that a tutorial review that guides beginners particularly towards pyrolysis implementation, from different biomasses to the thermal conversion process and conditions, is scarce. An effective understanding of pre-to-main pyrolysis stages, alongside corresponding standard methodologies, would help beginners discuss anticipated results. To support the existing information, therefore, this review sought to seek how to navigate pyrolysis implementation, specifically considering factors and thermochemical operating methods for biomass conversion, drawing the ideas from: (a) the evolving nature of the thermal conversion process; (b) the potential inter-relatedness between individual components affecting pyrolysis-based research; (c) pre- to post-pyrolysis’ engagement strategies; (d) potential feedstock employed in the thermal conversion processes; (e) the major pre-treatment strategies applied to feedstocks; (f) system performance considerations between pyrolysis reactors; and (g) differentiating between the reactor and operation parameters involved in the thermal conversion processes. Moreover, pre-pyrolysis activity tackles biomass selection/analytical measurements, whereas the main pyrolysis activity tackles treatment methods, reactor types, operating processes, and the eventual product output. Other areas that need beginners’ attention include high-pressure process reactor design strategies and material types that have a greater potential for biomass.

“…Leaching has been proven as a positive pretreatment for BTX production in CFP from biomass. Khan et al 67 investigated the CFP of acid leached rice straw. 96% K, 74.73% Ca, 94.78% Mg. and 98.33% Na metals in rice straw were removed, and a higher heating value was increased via acid leaching.…”

In order to reduce dependence on nonrenewable resources and environmental damage, alternative renewable feedstocks are needed to replace fossil fuels to produce benzene, toluene, and xylene (BTX). Biomass has been considered an ideal feedstock because of its abundance, renewability, and carbon neutrality. Catalytic fast pyrolysis (CFP) is a potential method for the conversion of biomass to BTX. This paper summarizes the mechanisms and pathways of biomass to BTX via CFP and attempts to provide an overview of the factors affecting BTX production from biomass in terms of feedstocks, catalysts, process configurations, and pyrolysis conditions. On the basis of understanding these factors, potential optimization methods to enhance the yield and selectivity of BTX from biomass CFP are proposed.

“…The high purity of synthetic zeolites enhances reproducibility compared to natural material. However, the production cost of synthetic zeolites may restrict their industrial use 15,16 . The main uses of natural zeolites are as cement additive, 17 nutrient‐release agent, 18 catalyst, 19 adsorbent, 20,21 ion‐exchanger, 22,23 bactericides, 24 hybrid membranes, 25,26 electrodes, 27,28 capacitors and sensors, 29,30 or even in energy storage processes 31,32 .…”

BACKGROUND Drugs and pesticides are emerging contaminants, and their presence in surface and groundwater have been increasing. Therefore, this work aims to study the modification of natural zeolite to remove these contaminants from water. RESULTS Among the modifications carried out, hydrothermal treatment in the presence of surfactant (CTAB) was highlighted. The hydrothermal treatment with surfactant provided a structural rearrangement. As a result, the zeolite became more hydrophobic, with a smaller specific area and a more significant amount of mesopores and macropores. Changes in textural and chemical characteristics resulted in a significant increase in the removal of the evaluated pesticides and drugs. In order to evaluate the potential of zeolites to remove emerging contaminants under conditions closer to reality, the modified samples were evaluated in the adsorption process of simulated contaminated water. The maximum adsorption capacities obtained were 28.24, 3.07, and 20.06 mg g−1 for 2,4‐D, diuron, and diclofenac, respectively, using HT‐H2O_CTAB under conditions closer to real water treatment (30 °C and natural pH of the solution). CONCLUSION The results demonstrate that hydrothermal modification with CTAB is a promising ‘chimie douce’ technique to use natural zeolites to remove emerging contaminants. © 2022 Society of Chemical Industry (SCI).
